Fluoride is a natural mineral that naturally occurs throughout the world – it is also the active ingredient of many toothpastes specifically for its remineralizing effects on enamel, often repairing the tooth surface and reducing the risk of caries.

The use of fluoridated toothpaste is highly recommended by dental professionals; whereby studies suggest that the correct daily use of fluoride on the dentition of children has a high caries-preventive effect and therefore prevents has potential to prevent ECC. However, it is important to use fluoridated toothpastes correctly; children below the age of two do not usually require toothpaste unless they are already at a high risk of ECC as diagnosed by a dental professional, and therefore it is it is recommended to use a small sized ‘smear’ of toothpaste to incorporate fluoride, with caution removing the toothpaste from within the mouth and not allowing the child to swallow the substances.

Personal hygiene care consists of proper brushing and flossing daily. The purpose of oral hygiene is to minimize any etiologic agents of disease in the mouth. The primary focus of brushing and flossing is to remove and prevent the formation of plaque or dental biofilm. Plaque consists mostly of bacteria. As the amount of bacterial plaque increases, the tooth is more vulnerable to dental caries when carbohydrates in the food are left on teeth after every meal or snack. A toothbrush can be used to remove plaque on accessible surfaces, but not between teeth or inside pits and fissures on chewing surfaces. When used correctly, dental floss removes plaque from areas that could otherwise develop proximal caries but only if the depth of sulcus has not been compromised. Other adjunct oral hygiene aids include interdental brushes, water picks, and mouthwashes.

However oral hygiene is probably more effective at preventing gum disease (periodontal disease) than tooth decay. Food is forced inside pits and fissures under chewing pressure, leading to carbohydrate-fueled acid demineralisation where the brush, fluoride toothpaste, and saliva have no access to remove trapped food, neutralise acid, or remineralise demineralised tooth like on other more accessible tooth surfaces. (Occlusal caries accounts for between 80 and 90% of caries in children (Weintraub, 2001).) Higher concentrations of fluoride (>1,000 ppm) in toothpaste also helps prevents tooth decay, with the effect increasing with concentration. Chewing fibre like celery after eating forces saliva inside trapped food to dilute any carbohydrate like sugar, neutralise acid and remineralise demineralised tooth. The teeth at highest risk for carious lesions are the permanent first and second molars due to length of time in oral cavity and presence of complex surface anatomy.

Professional hygiene care consists of regular dental examinations and professional prophylaxis (cleaning). Sometimes, complete plaque removal is difficult, and a dentist or dental hygienist may be needed. Along with oral hygiene, radiographs may be taken at dental visits to detect possible dental caries development in high-risk areas of the mouth (e.g. "bitewing" X-rays which visualize the crowns of the back teeth).

Regular use of a mouthguard during sports and other high-risk activities (such as military training) is the most effective prevention for dental trauma. Custom made mouthguard is preferable as it fits well, provides comfort and adequate protection. However, studies in various high-risk populations for dental injuries have repeatedly reported low compliance of individuals for the regular using of mouthguard during activities. Moreover, even with regular use, effectiveness of prevention of dental injuries is not complete, and injuries can still occur even when mouthguards are used as users are not always aware of the best makes or size, which inevitably result in a poor fit.

One of the most important measures is to impart knowledge and awareness about dental injury to those who are involved in sports environments like boxing and in school children in which they are at high risk of suffering dental trauma through an extensive educational campaign including lectures,leaflets,Posters which should be presented in an easy understandable way.

On eruption of the first primary tooth in a child, tooth brushing and cleaning should be performed by an adult. This is important as the plaque that attaches to the surface of the tooth has bacteria that have the ability to cause caries (decay) on the tooth surface.

It is recommended to brush children’s teeth using a soft bristled, age and size appropriate toothbrush and age appropriate toothpaste twice daily, however children below the age of two usually don’t require toothpaste. These researches also suggest that it is suitable to brush children’s teeth until they reach the approximate age of 6; where they will begin to learn adequate dexterity and cognition needed for adequate brushing by themselves. It is encouraged to watch children brushing their teeth until they are competently able to brush appropriately alone.

The use of dental sealants is a means of prevention. A sealant is a thin plastic-like coating applied to the chewing surfaces of the molars to prevent food from being trapped inside pits and fissures. This deprives resident plaque bacteria of carbohydrate, preventing the formation of pit and fissure caries. Sealants are usually applied on the teeth of children, as soon as the teeth erupt but adults are receiving them if not previously performed. Sealants can wear out and fail to prevent access of food and plaque bacteria inside pits and fissures and need to be replaced so they must be checked regularly by dental professionals.

Calcium, as found in food such as milk and green vegetables, is often recommended to protect against dental caries. Fluoride helps prevent decay of a tooth by binding to the hydroxyapatite crystals in enamel. Streptococcus mutans is the leading cause of tooth decay. Low concentration fluoride ions act as bacteriostatic therapeutic agent and high concentration fluoride ions are bactericidal. The incorporated fluorine makes enamel more resistant to demineralization and, thus, resistant to decay. Topical fluoride is more highly recommended than systemic intake such as by tablets or drops to protect the surface of the teeth. This may include a fluoride toothpaste or mouthwash or varnish. Standard fluoride toothpaste (1,000–1,500 ppm) is more effective than low fluoride toothpaste (< 600ppm) to prevent dental caries. After brushing with fluoride toothpaste, rinsing should be avoided and the excess spat out. Many dental professionals include application of topical fluoride solutions as part of routine visits and recommend the use of xylitol and amorphous calcium phosphate products. Silver diamine fluoride may work better than fluoride varnish to prevent cavities. Water fluoridation also lowers the risk of tooth decay.

An oral health assessment carried out before a child reaches the age of one may help with management of caries. The oral health assessment should include checking the child’s history, a clinical examination, checking the risk of caries in the child including the state of their occlusion and assessing how well equipped the child’s parent or carer is to help the child prevent caries. In order to further increase a child’s cooperation in caries management, good communication by the dentist and the rest of the staff of a dental practice should be used. This communication can be improved by calling the child by their name, using eye contact and including them in any conversation about their treatment.

Vaccines are also under development.

When a diagnosis of bruxism has been confirmed, it is recommended that the patient buy a full-coverage acrylic occlusal splint, such as a Michigan Splint or Tanner appliance, to prevent further bruxism. Patients must be monitored closely, with clinical photographs 6–12 monthly to evaluate if the tooth surface loss is being prevented.

In order for successful treatment of abrasion to occur, the aetiology first needs to be identified. The most accurate way of doing so is completing a thorough medical, dental, social and diet history. All aspects needs to be investigated as in many cases the cause of abrasion can be multi-factorial. Once a definitive diagnosis is completed the appropriate treatment can commence.

Treatment for abrasion can present in varying difficulties depending on the current degree or progress caused by the abrasion. Abrasion often presents in conjunction with other dental conditions such as attrition, decay and erosion however the below treatment is for abrasion alone. Successful treatment focuses on the prevention and progression on the condition and modifies the current habit/s instigating the condition.

The best method for the prevention of knocked-out teeth is the use of helmets and mouth protectors. Mouth protectors can be very inexpensive, however, the compliance rate for their use is poor. Studies have shown that, even when mandated, athletes and other high risk individuals often will not use them. Also, even with their use, mouth guards can be knocked-out, leaving the user unprotected.

At-home treatments include desensitizing toothpastes or dentifrices, potassium salts, mouthwashes and chewing gums.

A variety of toothpastes are marketed for dentin hypersensitivity, including compounds such as strontium chloride, strontium acetate, arginine, calcium carbonate, hydroxyapatite and calcium sodium phosphosilicate. Desensitizing chewing gums and mouthwashes are also marketed.

Potassium-containing toothpastes are common; however, the mechanism by which they may reduce hypersensitivity is unclear. Animal research has demonstrated that potassium ions placed in deep dentin cavities cause nerve depolarization and prevent re-polarization. It is not known if this effect would occur with the twice-daily, transient and small increase in potassium ions in saliva that brushing with potassium-containing toothpaste creates. In individuals with dentin hypersensitivity associated with exposed root surfaces, brushing twice daily with toothpaste containing 5% potassium nitrate for six to eight weeks reduces reported sensitivity to tactile, thermal and air blast stimuli. However, meta analysis reported that these individuals' subjective report of sensitivity did not significantly change after six to eight weeks of using the potassium nitrate toothpaste.

Desensitizing toothpastes containing potassium nitrate have been used since the 1980s while toothpastes with potassium chloride or potassium citrate have been available since at least 2000. It is believed that potassium ions diffuse along the dentinal tubules to inactivate intradental nerves. However, , this has not been confirmed in intact human teeth and the desensitizing mechanism of potassium-containing toothpastes remains uncertain. Since 2000, several trials have shown that potassium-containing toothpastes can be effective in reducing dentin hypersensitivity, although rinsing the mouth after brushing may reduce their efficacy.

Studies have found that mouthwashes containing potassium salts and fluorides can reduce dentine hypersensitivity, although rarely to any significant degree. , no controlled study of the effects of chewing gum containing potassium chloride has been made, although it has been reported as significantly reducing dentine hypersensitivity.

Nano-hydroxyapatite (nano-HAp) is considered one of the most biocompatible and bioactive materials, and has gained wide acceptance in dentistry in recent years. An increasing number of reports have shown that nano-hydroxyapatite shares characteristics with the natural building blocks of enamel having the potential, due to its particle size, to occlude exposed dentinal tubules helping to reduce hypersensitivity and enhancing teeth remineralization.

For this reason, the number of toothpastes and mouthwashes that already incorporate nano-hydroxyapatite as a desensitizing agent is increasing.

Cosmetic or functional intervention may be required if tooth surface loss is pathological or if there has been advanced loss of tooth structure. The first stage of treatment involves managing any associated conditions, such as fractured teeth or sharp cusps or incisal edges. These can be resolved by restoring and polishing sharp cusps. Then, desensitizing agents such as topical fluoride varnishes can be applied, and at home desensitising toothpastes recommended. Many restorative options have been proposed, such as direct composite restorations, bonded cast metal restorations, removable partial dentures, orthodontic treatment, crown lengthening procedures and protective splints. The decision to restore the dentition depends on the wants and needs of the patient, the severity of tooth surface loss and whether tooth surface loss is active. The use of adhesive materials to replace lost tooth structure can be performed as a conservative and cost-effective approach before a more permanent solution of crowns or veneers is considered.

The aetiology of dental abrasion can be due to a single stimuli or, as in most cases, multi-factorial. The most common cause of dental abrasion, is the combination of mechanical and chemical wear.

Tooth brushing is the most common cause of dental abrasion, which is found to develop along the gingival margin, due to vigorous brushing in this area. The type of toothbrush, the technique used and the force applied when brushing can influence the occurrence and severity of resulting abrasion. Further, brushing for extended periods of time (exceeding 2-3 min) in some cases, when combined with medium/hard bristled toothbrushes can cause abrasive lesions.

Different toothbrush types are more inclined to cause abrasion, such as those with medium or hard bristles. The bristles combined with forceful brushing techniques applied can roughen the tooth surface and cause abrasion as well as aggravating the gums. Repetitive irritation to the gingival margin can eventually cause recession of the gums. When the gums recede, the root surface is exposed which is more susceptible to abrasion.

Comparatively, electric toothbrushes have less abrasive tendencies.

Types of toothpastes can also damage enamel and dentine due to the abrasive properties. Specific ingredients are used in toothpaste to target removal of the bio-film and extrinsic staining however in some cases can contribute to the pastes being abrasive.

Whitening toothpastes are found to be one of the most abrasive types of toothpastes, according to the RDA Scale, detailed below. In-home and clinical whitening have been proven to increase the likelihood of an individual experiencing dental abrasion. It is believed that dental abrasion due to the whitening process is caused by a combination of both mechanical and chemical irritants, for example, using whitening toothpaste and at home bleaching kits together. However, if an individual is regimented in their after-whitening care then they can avoid loss of dentine minerals and in turn abrasion can be avoided. (that contribute to developing abrasion).

Another factor that can contribute to abrasion is alteration of pH levels in the saliva. This can be sugary/ acidic foods and liquids. The reasoning behind this is that an increase in acidity of saliva can induce demineralization and therefore compromising the tooth structure to abrasive factors such as tooth brushing or normal wear from mastication. When the tooth structure is compromised, this is where the mineral content of the saliva can create shallow depressions in the enamel and thus, when brushed can cause irreparable damage on tooth surface. The dental abrasion process can be further stimulated and accelerated through the effects of dental Acid erosion.

Gingival recession and cervical tooth wear can be avoided by healthy dietary and oral hygiene practices. By using a non-traumatic toothbrushing technique (i.e. a recommended technique such as the modified Bass technique rather than indiscriminately brushing the teeth and gums in a rough scrubbing motion) will help prevent receding gums and tooth wear around the cervical margin of teeth. Non-abrasive toothpaste should be used, and brushing should be carried out no more than twice per day for two minutes on each occasion. Excessive use of acidic conditions around the teeth should be avoided by limiting consumption of acidic foods and drinks, and seeking medical treatment for any cause of regurgitation/reflux of stomach acid. Importantly, the teeth should not be brushed immediately after acidic foods or drinks. A non-abrasive diet will also help to prevent tooth wear. Flossing each day also helps to prevent gum recession caused by gum disease.

Teeth whitening products can make your teeth sensitive. However, the increased sensitivity is temporary and will go away within a few days. If teeth sensitivity is experienced after using a teeth whitening product, taking a break may help.

Dental fluorosis may or may not be of cosmetic concern. In some cases, there may be varying degrees of negative psychosocial effects. The treatment options are:

- Tooth bleaching

- Micro-abrasion

- Composite fillings

- Veneers

- Crowns

Generally, more conservative options such as bleaching are sufficient for mild cases.

Gingivitis can be prevented through regular oral hygiene that includes daily brushing and flossing. Hydrogen peroxide, saline, alcohol or chlorhexidine mouth washes may also be employed. In a 2004 clinical study, the beneficial effect of hydrogen peroxide on gingivitis has been highlighted.

Rigorous plaque control programs along with periodontal scaling and curettage also have proved to be helpful, although according to the American Dental Association, periodontal scaling and root planing are considered as a treatment for periodontal disease, not as a preventive treatment for periodontal disease. In a 1997 review of effectiveness data, the U.S. Food and Drug Administration (FDA) found clear evidence showing that toothpaste containing triclosan was effective in preventing gingivitis.

Preventive and management strategies include the following:

- Avoid sweet and acid foods. Even low sugar contained in fruit is bad for the teeth since it is the sugar/acid exposure time which erodes the teeth, not the amount of sugar.

- Modifying the pH of the food or beverage contributing to the problem, or changing lifestyle to avoid the food or beverage.

- Rinsing immediately after drinking or eating.

- Drinking through a straw

- Avoid abrasive forces. Use a soft bristled toothbrush and brush gently. Avoid brushing immediately after consuming acidic food and drink as teeth will be softened. Leave at least half an hour of time in between. Rinsing with water is better than brushing after consuming acidic foods and drinks.

- Using a remineralizing agent, such as sodium fluoride solution in the form of a fluoride mouthrinse, tablet, or lozenge, immediately before brushing teeth.

- Applying fluoride gels or varnishes to the teeth.

- Drinking milk or using other dairy products.

- Dentine bonding agents applied to areas of exposed dentin

- Use a neutralizing agent such as antacid tablets only as a last-resort. They have negative long-run effects.

- Treating the underlying medical disorder or disease.

Since most toothache is the result of plaque-related diseases, such as tooth decay and periodontal disease, the majority of cases could be prevented by avoidance of a cariogenic diet and maintenance of good oral hygiene. That is, reduction in the number times that refined sugars are consumed per day and brushing the teeth twice a day with fluoride toothpaste and flossing. Regular visits to a dentist also increases the likelihood that problems are detected early and averted before toothache occurs. Dental trauma could also be significantly reduced by routine use of mouthguards in contact sports.

The management depends on the type of injury involved and whether it is a baby or an adult tooth. The Dental Trauma Guide is an evidence-based and up-to-date resource to aid management of dental trauma. If teeth are completely knocked out baby front teeth should not be replaced. The area should be cleaned gently and the child brought to see a dentist. Adult front teeth (which usually erupt at around 6 years of age) can be replaced immediately if clean. See below and the Dental Trauma Guide website for more details. If a tooth is avulsed, make sure it is a permanent tooth (primary teeth should not be replanted, and instead the injury site should be cleaned to allow the adult tooth to begin to erupt).

- Reassure the patient and keep them calm.

- If the tooth can be found, pick it up by the crown (the white part). Avoid touching the root part.

- If the tooth is dirty, wash it briefly (10 seconds) under cold running water but do not scrub the tooth.

- Place the tooth back in the socket where it was lost from, taking care to place it the correct way (matching the other tooth)

- Encourage the patient to bite on a handkerchief to hold the tooth in position.

- If it is not possible to replace the tooth immediately, place it in a glass of milk or a container with the patient's saliva or in the patient's cheek (keeping it between the teeth and the inside of the cheek - note this is not suitable for young children who may swallow the tooth). Transporting the tooth in water is not recommended, as this will damage the delicate cells that make up the tooth's interior.

- Seek emergency dental treatment immediately.

The poster "Save a Tooth" is written for the public and is available in several languages—Spanish, English, Portuguese, French, Icelandic, Italian—and can be obtained at the IADT website.

For other injuries, it is important to keep the area clean - by using a soft toothbrush and antiseptic mouthwash such as chlorhexidine gluconate. Soft foods and avoidance of contact sports it also recommended in the short term. Dental care should be sought as quickly as possible.

Fluorosis is extremely common, with 41% of adolescents having definite fluorosis, and another 20% "questionably" having fluorosis according to the Centers for Disease Control.

The U.S. Centers for Disease Control found a 9 percentage point increase in the prevalence of confirmed dental fluorosis in a 1999-2002 study of American children and adolescents than was found in a similar survey from 1986-1987 (from 22.8% in 1986-1987 to 32% in 1999-2002). In addition, the survey provides further evidence that African Americans suffer from higher rates of fluorosis than Caucasian Americans.

The condition is more prevalent in rural areas where drinking water is derived from shallow wells or hand pumps. It is also more likely to occur in areas where the drinking water has a fluoride content greater than 1 ppm (part per million).

If the water supply is fluoridated at the level of 1 ppm, one must consume one litre of water in order to take in 1 mg of fluoride. It is thus improbable a person will receive more than the tolerable upper limit from consuming optimally fluoridated water alone.

Fluoride consumption can exceed the tolerable upper limit when someone drinks a lot of fluoride-containing water in combination with other fluoride sources, such as swallowing fluoridated toothpaste, consuming food with a high fluoride content, or consuming fluoride supplements. The use of fluoride supplements as a prevention for tooth decay is rare in areas with water fluoridation, but was recommended by many dentists in the UK until the early 1990s.

Dental fluorosis can be prevented by lowering the amount of fluoride intake to below the tolerable upper limit.

In November 2006 the American Dental Association published information stating that water fluoridation is safe, effective and healthy; that enamel fluorosis, usually mild and difficult for anyone except a dental health care professional to see, can result from ingesting more than optimal amounts of fluoride in early childhood; that it is safe to use fluoridated water to mix infant formula; and that the probability of babies developing fluorosis can be reduced by using ready-to-feed infant formula or using water that is either free of fluoride or low in fluoride to prepare powdered or liquid concentrate formula. They go on to say that the way to get the benefits of fluoride but minimize the risk of fluorosis for a child is to get the right amount of fluoride, not too much and not too little. "Your dentist, pediatrician or family physician can help you determine how to optimize your child’s fluoride intake."

There are many storage media available for knocked-out tooth storage. The most often recommended are: saliva, physiologic saline, milk and pH balanced cell preserving fluids. Water and ice have been shown to damage the tooth root cells, and as such, avulsed teeth should never be stored in them. The osmolality and pH of water and ice is very low (7-17mOs) compared to normal cell pressure (280 mOs). When a knocked-out tooth is placed in water, the cells attempt to equalize with the surrounding environment, the cell fluid tries to move to the outside pressure environment and burst. Water with table salt in it is damaging to the knocked out teeth.

Saliva, that is placing the tooth under the accident victim’s tongue or in the cheek, has been recommended. Saliva, as a storage media, causes twice damage as water. Its osmolality is very low, causing bursting of the tooth root cells, but additionally, because saliva is filled with its normal flora of microorganisms, it will severely infect the tooth root cells. When the tooth is replanted, not only will the cells be necrotic but they will also infect the bone socket.

Physiologic saline has a fairly compatible osmolality and will not cause cell swelling but it lacks the metabolites and glucose necessary for maintenance of normal cell metabolism.

Milk has been also recommended as a storage medium for avulsed teeth. Its advantage is the high availability of fresh whole milk. Only whole milk can be used for tooth preservation. Skim milk and heavy cream do not have the correct fluid pressure and will cause damage to the root cells. Milk has no observed regenerative properties for cells on knocked out teeth.

It was discovered 30 years ago that milk was less damaging to knocked out teeth than water or saliva. It was recommended because it has a compatible osmolality (fluid pressure) to tooth root cells and it is thought to be readily available. However, like physiologic saline, milk lacks the necessary metabolites and glucose necessary to maintain normal cell metabolism of the tooth root cells. The cells on knocked-out tooth roots in milk do not die immediately but are unable to replicate (mitosis) and so are less able to reform new cells when replanted.

The most optimum storage media that are available have been shown to be pH balanced cell preserving solutions. The best known and most extensively tested is called Hank’s Balanced Salt Solution (HBSS). It has all of the metabolites such as Ca, phosphate ions, K+ and glucose that are necessary to maintain normal cell metabolism for long periods of time. HBSS has been extensively tested in dental and medical research for the past twenty years. This research has shown that 90% of cells stored in HBSS for 24 hours maintain their normal viability and after four days, still have 70%viable. In research studies, extracted dog’s teeth that have been placed in HBSS for four days can still be replanted with little signs of resorption. Hank's Balanced Salt Solution is found in a Save-A-Tooth, a storage device for the storage, preservation, and regeneration of tooth root cells.

HBSS also has been shown to be capable of replacing lost cell metabolites. Since a cell that has been cut off from its blood supply depletes its stored metabolites after fifteen minutes, a tooth that has been extra-oral for one hour has less vital cells to reconnect with the bone ligament cells.

Some studies in dental research have shown that knocked out teeth that have been dry for up to one hour will have less resorption if they are soaked in a HBSS for 30 minutes prior to replantation. In these studies, dog’s teeth were extracted and left dry for 30, 45 and 60 minutes and then soaked in HBSS for 30 minutes and then reimplanted. These teeth showed 50% less replacement resorption following reimplantation. It has also been shown that keeping the teeth cold while in the HBSS does not affect success.

Many other types of storage liquids have been tested such as powdered milk, Enfamil, Gatorade, and contact lens solution. All of them have been shown to either be ineffective or damaging to avulsed tooth.

A systematic review reported that there is some evidence that rinsing with chlorhexidine (0.12% or 0.2%) or placing chlorhexidine gel (0.2%) in the sockets of extracted teeth reduces the frequency of dry socket. Another systematic review concluded that there is evidence that prophylactic antibiotics reduce the risk of dry socket (and infection and pain) following third molar extractions of wisdom teeth, however their use is associated with an increase in mild and transient adverse effects. The authors questioned whether treating 12 patients with antibiotics to prevent one infection would do more harm overall than good, in view of the potential side effects and also of antibiotic resistance. Nevertheless, there is evidence that in individuals who are at clear risk may benefit from antibiotics. There is also evidence that antifibrinolytic agents applied to the socket after the extraction may reduce the risk of dry socket.

Some dentists and oral surgeons routinely debride the bony walls of the socket to encourage hemorrhage (bleeding) in the belief that this reduces the incidence of dry socket, but there is no evidence to support this practice. It has been suggested that dental extractions in females taking oral contraceptives be scheduled on days without estrogen supplementation (typically days 23–28 of the menstrual cycle). It has also been suggested that teeth to be extracted be scaled prior to the procedure.

Prevention of alveolar osteitis can be exacted by following post-operative instructions, including:

1. Taking any recommended medications

2. Avoiding intake of hot fluids for one to two days. Hot fluids raise the local blood flow and thus interfere with organization of the clot. Therefore, cold fluids and foods are encouraged, which facilitate clot formation and prevent its disintegration.

3. Avoiding smoking. It reduces the blood supply, leading to tissue ischemia, reduced tissue perfusion and eventually higher incidence of painful socket.

4. Avoiding drinking through a straw or spitting forcefully as this creates a negative pressure within the oral cavity leading to an increased chance of blood clot instability.

Disclosing tablets are similar to that of disclosing gels, except that they are placed in the mouth and chewed on for approximately one minute. The remaining tablet or saliva is then spit out. Disclosing gels will show the presence of the plaque, but will often not show the level of maturity of the plaque. Disclosing tablets are often prescribed or given to patients with orthodontic appliances for use before and after tooth brushing to ensure optimal cleaning. These are also helpful educational tools for young children or patients that are struggling to remove dental plaque in certain areas. Disclosing gels and tablets are useful for individuals of all ages in ensuring efficient dental plaque removal.

Treatment may include smoothing, fluoride treatment, and crown restoration.

The focus of treatment is to remove plaque. Therapy is aimed at the reduction of oral bacteria and may take the form of regular periodic visits to a dental professional together with adequate oral hygiene home care. Thus, several of the methods used in the prevention of gingivitis can also be used for the treatment of manifest gingivitis, such as scaling, root planing, curettage, mouth washes containing chlorhexidine or hydrogen peroxide, and flossing. Interdental brushes also help remove any causative agents.

Powered toothbrushes work better than manual toothbrushes in reducing the disease.

The active ingredients that "reduce plaque and demonstrate effective reduction of gingival inflammation over a period of time" are triclosan, chlorhexidine digluconate, and a combination of thymol, menthol, eucalyptol, and methyl salicylate. These ingredients are found in toothpaste and mouthwash. Hydrogen peroxide was long considered a suitable over-the-counter agent to treat gingivitis. There has been evidence to show the positive effect on controlling gingivitis in short-term use. A study indicates the fluoridated hydrogen peroxide-based mouth rinse can remove teeth stain and reduce gingivitis.

Based on a limited evidence, mouthwashes with essential oils may also be useful, as they contain ingredients with anti-inflammtory properties, such as thymol, menthol and eucalyptol.

The bacteria that causes gingivitis can be controlled by using an oral irrigator daily with a mouthwash containing an antibiotic. Either amoxicillin, cephalexin, or minocycline in 16 ounces of a non-alcoholic fluoride mouthwash is an effective mixture.

Overall, intensive oral hygiene care has been shown to improve gingival health in individuals with well-controlled type 2 diabetes. Periodontal destruction is also slowed down due to the extensive oral care. Intensive oral hygiene care (oral health education plus supra-gingival scaling) without any periodontal therapy improves gingival health, and may prevent progression of gingivitis in well-controlled diabetes.

Acidic drinks and foods lower the pH level of the mouth so consuming them causes the teeth to demineralise. Drinks low in pH levels that cause dental erosion include fruit juices, sports drinks, wine, beer and carbonated drinks. Orange and apple juices are common culprits among fruit juices. Carbonated drinks such as colas, lemonades are also very acidic, as are fruit-flavoured drinks and dilutables. Frequency rather than total intake of acidic juices is seen as the greater factor in dental erosion; infants using feeding bottles containing fruit juices (especially when used as a comforter) are therefore at greater risk of acid erosion.

Saliva acts as a buffer, regulating the pH when acidic drinks are ingested. Drinks vary in their resistance to the buffering effect of saliva. Studies show that fruit juices are the most resistant to saliva's buffering effect, followed by, in order: fruit-based carbonated drinks and flavoured mineral waters, non-fruit-based carbonated drinks, sparkling mineral waters; Mineral water being the least resistant. Because of this, fruit juices in particular, may prolong the drop in pH levels.

A number of medications such as vitamin C, aspirin and some iron preparations are acidic and may contribute towards acid erosion.

Dental caries is an infectious disease caused primarily by "Streptococcus mutans", characterized by acid demineralization of the enamel, which can progress to further breakdown of the more organic, inner dental tissue (dentin). Everybody is susceptible to caries but the probability of development depends on the patient’s individual disease indicators, risk factors and preventive factors. Factors that are considered high-risk for developing carious lesions on the teeth include:

- Low fluoride exposure

- Time, length, and frequency of sugar consumption

- Quality of tooth cleaning

- Fluctuations in salivary flow rates and composition

- Behavior of the individual

- Socioeconomic status of the individual

- Quality and composition of biofilms

Organic acids released from dental plaque lead to demineralization of the adjacent tooth surface, and consequently to dental caries. Saliva is also unable to penetrate the build-up of plaque and thus cannot act to neutralize the acid produced by the bacteria and remineralize the tooth surface.
