Endodontic intervention can help conserve the existing health of affected permanent teeth. It is difficult to perform an endodontic therapy on teeth that develop abscesses as a resultant of obliteration of the pulp chambers and root canals. An alternative to conventional therapy would be retrograde filling and periapical curettage. However, these therapies are not recommended for teeth with roots that are too short.

Preventive and restorative care are important as well as esthetics as a consideration. This ensures preservation of the patient's vertical face height between their upper and lower teeth when they bite together. The basis of treatment is standard throughout the different types of DI where prevention, preservation of occlusal face height, maintenance of function, and aesthetic needs are priority. Preventive efforts can limit pathology occurring within the pulp, which may render future endodontic procedures less challenging, with better outcomes.

- Challenges are associated with root canal treatment of teeth affected by DI due to pulp chamber and root canal obliteration, or narrowing of such spaces.

- If root canal treatment is indicated, it should be done in a similar way like with any other tooth. Further consideration is given for restoring the root-treated tooth as it has weaker dentine which may not withstand the restoration.

Preservation of occlusal face height may be tackled by use of stainless steel crowns which are advocated for primary teeth where occlusal face height may be hugely compromised due to loss of tooth tissue as a result of attrition, erosion of enamel.

In most cases, full-coverage crowns or veneers (composite/porcelain) are needed for aesthetic appearance, as well as to prevent further attrition. Another treatment option is bonding, putting lighter enamel on the weakened enamel of the teeth and with lots of treatments of this bonding, the teeth appear whiter to the eye, but the teeth on the inside and under that cover are still the same. Due to the weakened condition of the teeth, many common cosmetic procedures such as braces and bridges are inappropriate for patients with Dentinogenesis imperfecta and are likely to cause even more damage than the situation they were intended to correct.

Dental whitening (bleaching) is contraindicated although it has been reported to lighten the color of DI teeth with some success; however, because the discoloration is caused primarily by the underlying yellow-brown dentin, this alone is unlikely to produce normal appearance in cases of significant discoloration.

If there is considerable attrition, overdentures may be prescribed to prevent further attrition of remaining teeth and for preserving the occlusal face height.

The best method of maintaining the health of teeth is to practice exemplary oral hygiene. More tooth loss is likely to occur if intervention takes place. However, factors such as present complaint, patient age, severity of the problem, can affect the treatment plan or options.

Bisphosphonates have recently been introduced to treat several bone disorders, which include osteogenesis imperfecta.

A recognized risk of this drug relevant to dental treatments is bisphosphonate-associated osteonecrosis of the jaw (BRONJ). Occurrences of this risk is associated with dental surgical procedures such as extractions.

Dental professionals should therefore proceed with caution when carrying out any dental procedures in patients who have Type 2 DI who may be on bisphosphonate drug therapy.

Preventive maintenance therapy for the oral effects of TDO involve frequent dental cleanings, professional application of desensitizing medication, diet counseling, and oral hygiene instructions in proper home care and maintenance; medicated dental rinses and toothpastes are also prescribed as people suffering from TDO are more prone to oral hard tissue disease and early tooth loss. If restorative dentistry is performed without orthodontics to correct the protrusion of the lower jaw, a dental night guard worn at bedtimes on the upper or lower teeth to protect them from the effects of grinding may be recommended.

In extreme cases, tooth loss is inevitable, and the patient will consult with a prosthodontist to determine tooth replacement options such as dental implants, or partial dentures. There is no cure for TDO, but managing its oral and systemic affects is key to having the most favorable outcome from the disease. As the person affected by TDO ages, increased bone fractures may occur. The person suffering from TDO should watch for any pimple like masses on the gum tissue, pain or soreness in the teeth and gums, broken or chipped teeth, feeling of water in the ear or severe pain in the extremities which could indicate fracture.

The frequency of first permanent molar treatment for children with MIH is nearly 10 times greater compared to children without MIH. The available treatment modalities for MIH is extensive but the decision on which treatment should be used is complex and multi-factorial. Factors may include: condition severity, the patient’s dental age, the child/parent’s social background and expectations. There are treatment modalities available to manage children affected by MIH; however, the evidence supporting these modalities are still weak.

Involves repeated cycles of etching with 37% phosphoric acid followed by applying 5% sodium hypochlorite until improvement of discolouration is achieved. Clear resin composite or resin infiltrate can be used to seal the lesion after the technique.

Unerupted microdonts may require surgical removal to prevent the formation of cysts. Erupted microdonts, peg laterals especially, may cause cosmetic concern. Such teeth may be restored to resemble normal sized teeth, typically with composite build ups or crowns. Orthodontics may be required in severe cases to close gaps between the teeth.

The hair, teeth, and skeletal side effects of TDO are lifelong, and treatment is used to manage those effects. A person with TDO has the same life expectancy as a person without TDO. There are no cures or medications used to treat systemic effects of TDO, but medications for the frequent ear and dental infections can be used to manage its symptoms. A team based approach between dental specialists, oral and maxillofacial surgeons, and physicians is necessary for treating the systemic effects and improves the prognosis. It is also recommended for affected individuals to seek counseling to be better able to cope with any psychosocial problems due to oral and facial abnormalities that occur with TDO.

At home, a person suffering from TDO may be instructed to use frequent deep conditioning treatments and low manipulation hair styling to control shedding and hair loss. Clinical treatment involves the use of radiology to determine the effects that TDO has had on the surrounding teeth and bone structures. A series of appointments with the healthcare team are usually necessary to correct TDO abnormalities with treatment duration lasting from several months to through full oral-facial maturation stages.

Endodontic procedures are routinely recommended due to treatdental pulp exposure or periodontal abscess. Maxillofacial surgery may be required to establish a more appropriate mastication, skeletal, and esthetic relationship vertically between the teeth to improve functioning. Esthetic procedures such as dental crown (dentistry) or veneer (dentistry) are often performed to improve the physical look of the teeth and to strengthen the weak enamel caused by TDO.

All impacted teeth, unless otherwise contraindicated, are considered for surgical removal. Thus, dental extractions will often take place. The type of extraction (simple or surgical) often depends on the location of the teeth.

In some cases, for aesthetic purposes, a surgeon may wish to expose the canine. This may be achieved through open or closed exposure. Studies show no advantage of one method over another.

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.

Where there is an operculum of gingiva overlying the tooth that has become infected it can be treated with local cleaning, an antiseptic rinse of the area and antibiotics if severe. Definitive treatment can be excision of the tissue, however, recurrence of these infections is high. Pericoronitis, while a small area of tissue, should be viewed with caution, because it lies near the anatomic planes of the neck and can progress to life-threatening neck infections.

Although these teeth are usually asymptomatic and pose no threat to the individual, they are often extracted for aesthetic reasons. This is done particularly if the mesiodens is positioned in the maxillary central incisor region. The traditional method of removal is done by using bone chisels, although a more advanced technique has been found to be more beneficial, especially if surgery is required . Through the use of Piezoelectricity, Piezoelectric ultrasonic bone surgery may be more time consuming than the traditional method but it seems to reduce the post-operative bleeding and associated complications quite significantly.

If the condition is not affecting patient, no treatment is needed. Concrescence teeth could be reshaped and replaced with full crowns. However, if the teeth are having recurrent problems, non-restorable or pain, extraction should be considered.

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.

No intervention is usually recommended unless they are causing difficulty to the infant or mother.

However some recommend that they be removed as the tooth can cut or amputate the tip of the tongue.

They should be left in the mouth as long as possible to decrease the likelihood of removing permanent tooth buds with the natal tooth. They should also not be removed if the infant has hypoprothrombinemia. In case of complications when the natal teeth need to be removed, dental radiographs should be obtained whenever possible, and evaluated and followed up with pediatric dentists.

The oral rehabilitation of hypodontia, especially where a significant number of teeth have not developed, is often a multidisciplinary process, involving a specialist orthodontist, a consultant in restorative dentistry, and a paediatric dentist in the earlier years. The process of treating and managing hypodontia begins in the early years of the patient's dentition where absent teeth are identified and the process of maintaining the remaining teeth begins. This is largely conducted by the paediatric dentist with orthodontic input. Once all the adult teeth have erupted the orthodontist is likely to liaise with the restorative dentist regarding optimal positioning of teeth for subsequent replacement with prosthodontic methods. This may include the utilisation of a resin-retained bridge and implants for spaces or composite resin, veneers or crowns where teeth are diminutive or misshaped.

In 2006, retinoids and antibiotics have been used with a successful dental maintenance for one year. In the past, only Extraction of all teeth and construction of a complete denture were made.

An alternative to rehabilitation with conventional dental prothesis after total loss of the natural teeth was proposed by Drs Ahmad Alzahaili and his teacher Jean-François Tulasne (developer of the partial bone graft technique used). This approach entails transplanting bone extracted from the cortical external surface of the parietal bone to the patient’s mouth, affording the patient the opportunity to lead a normal life.

Notwithstanding this treatment do not scope the disease itself. Actually it is the repositioning of bone from calvaria to the maxillary bones, and placement of dental implants in a completely edentulous maxilae, when the patient has already lost all teeth. An already developed method to reconstruct maxillae in edentulous elderly people by other dental professionals.

There's still no real treatment to help those who suffer from this disease to keep all their natural teeth, though their exfoliation and loss can be delayed.

The maintenance of teeth is done by dental professionals with a procedure called scaling and root planing with the use of systemic antibiotics. The syndrome should be diagnosed as earlier as possible, so the teeth can be kept longer in the mouth, helping the development of the maxillary bones.

Wisdom teeth that are fully erupted and in normal function need no special attention and should be treated just like any other tooth. It is more challenging, however to make treatment decisions with asymptomatic, disease-free wisdom teeth, i.e. wisdom teeth that have no communication to the mouth and no evidence of clinical or radiographic disease (see Treatment controversy below).

Treatment is only required if the occlusion or bite of the person is compromised and causing other dental problems. Multiple long-term clinical problems can arise such as occlusal interferences, aesthetic disturbances, loss of pulp vitality, irritation of tongue during mastication and speech, caries and displacement of the affected tooth. Most people with talon cusp will live their normal lives unless the case is severe and causes a cascade of other dental issues that lead to additional health problems. This dental anomaly would not be considered fatal. Generally talon cusps on lower teeth require no treatment, but talon cusps on upper teeth may interfere with the bite mechanics and may need to be removed or reduced.

Small talon cusps that produce no symptoms or complication for a person can remain untreated. However large talon cusps should not.

Some common treatments include:

- Fissure sealing

- Composite resin restoration

- Reduction of cusp

- Pulpotomy

- Root canal (endodontic treatment)

- Extraction

The condition is usually benign, but it can cause mild irritation to soft tissues around the teeth and the tongue, and if large enough, may pose an aesthetic problem. Talon cusps that are too large are filed down with a motorized file, and then endodontic therapy is administered.

In order to prevent any future dental complications, when talon cusp is present due to an early diagnosis it would be best to see a dentist regularly every six months for routine dental checkups, remain under observation, brush and floss properly and undergo regular topical applications of fluoride gel to prevent caries and to promote enamel strength.

Treatment and prognosis are usually based upon keeping these teeth and preserving the alveolus. For erupted teeth, endodontics is an option if the tooth is devitalized and restorable. For unerupted teeth, function can be restored with a removable partial denture until all major growth has been completed and a final restoration can be placed.

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.

Management of teeth with PFE can include extractions of affected teeth, followed by orthodontic space closure or placement of a prosthetic implant with a bone graft. This option can only be applied to a single tooth that is affected. If multiple teeth are affected then, a segmental osteotomy may be performed to bring the entire segment into occlusion. However, minimal success has been shown following this procedure. These teeth usually are "non-responsive" to the orthodontic force and studies have shown that ankylosis of these teeth can occur if force applied.

Most alternative "at-home" gum disease treatments involve injecting antimicrobial solutions, such as hydrogen peroxide, into periodontal pockets via slender applicators or oral irrigators. This process disrupts anaerobic micro-organism colonies and is effective at reducing infections and inflammation when used daily. A number of other products, functionally equivalent to hydrogen peroxide, are commercially available, but at substantially higher cost. However, such treatments do not address calculus formations, and so are short-lived, as anaerobic microbial colonies quickly regenerate in and around calculus.

Doxycycline may be given alongside the primary therapy of scaling (see § initial therapy). Doxycycline has been shown to improve indicators of disease progression (namely probing depth and attachment level). Its mechanism of action involves inhibition of matrix metalloproteinases (such as collagenase), which degrade the teeth's supporting tissues (periodontium) under inflammatory conditions. To avoid killing beneficial oral microbes, only small doses of doxycycline (20 mg) are used.

Local application of statin may be useful.

Tongue crib is a removable applianced placed in the maxillary arch for the purpose of stopping the tongue thrusting habit. This appliance maybe used in patients with mixed dentition or permanent dentition. Tongue crib is attached through a bar to two bands placed on the upper 1st molars. The crib is shaped like a horseshoe with metal bars that prevent the thrusting habit. Tongue crib is known to eliminate habits in about 90% of the patients. (citation needed). Huang et al. published a study in 1990 which stated that patients who achieved a positive overbite during their tongue crib therapy had a good chance of maintaining that overbite after their orthodontic treatment. They credited this change to a change in the posterior positioning of the tongue due to the crib therapy.

Some of the side-effects of using a tongue-crib therapy is that this appliance may trap a lot of food which may cause inflammation around the appliance. In addition, repeated contact of tongue with the appliance may also lead to an imprint on the tongue which will self-resolve once the appliance is removed. It is important to note that this type of therapy will only work in patients who do not have a skeletal open bite tendency. Skeletal open bite tendency may be addressed via surgery or other treatments depending on the severity.
