The first line management of gingival overgrowth is improved oral hygiene, ensuring that the irritative plaque is removed from around the necks of the teeth and gums. Situations in which the chronic inflammatory gingival enlargement include significant fibrotic components that do not respond to and undergo shrinkage when exposed to scaling and root planing are treated with surgical removal of the excess tissue, most often with a procedure known as gingivectomy.

In DIGO, improved oral hygiene and plaque control is still important to help reduce any inflammatory component that may be contributing to the overgrowth. Reversing and preventing gingival enlargement caused by drugs is as easy as ceasing drug therapy or substituting to another drug. However, this is not always an option; in such a situation, alternative drug therapy may be employed, if possible, to avoid this deleterious side effect. In the case of immunosuppression, tacrolimus is an available alternative which results in much less severe gingival overgrowth than cyclosporin, but is similarly as nephrotoxic. The dihydropyridine derivative isradipidine can replace nifedipine for some uses of calcium channel blocking and does not induce gingival overgrowth.

This type of gingival enlargement is sometimes termed "drug induced gingival enlargement" or "drug influenced gingival enlargement", abbreviated to "DIGO". Gingival enlargement may also be associated with the administration of three different classes of drugs, all producing a similar response: Gingival overgrowth is a common side effect of phenytoin, termed "Phenytoin-induced gingival overgrowth" (PIGO).

- anticonvulsants (such as phenytoin, phenobarbital, lamotrigine, vigabatrin, ethosuximide, topiramate and primidone NOT common for valproate)

- calcium channel blockers (antihypertensives such as nifedipine, amlodipine, and verapamil). The dihydropyridine derivative isradipidine can replace nifedipine and does not induce gingival overgrowth.

- cyclosporine, an immunosuppresant.

Of all cases of DIGO, about 50% are attributed to phenytoin, 30% to cyclosporins and the remaining 10-20% to calcium channel blockers.

Drug-induced enlargement has been associated with a patient's genetic predisposition, and its association with inflammation is debated. Some investigators assert that underlying inflammation is necessary for the development of drug-induced enlargement, while others purport that the existing enlargement induced by the drug effect compounds plaque retention, thus furthering the tissue response. Careful attention to oral hygiene may reduce the severity of gingival hyperplasia. In most cases, discontinuing the culprit drug resolves the hyperplasia.

Treatment is by surgical excision (complete removal) of the fibrous tissue overgrowth and addressing the causative factor to prevent recurrence of the lesion. Other sources suggest that surgical excision may not be required in all cases. Common techniques for removal of the excess tissue include traditional removal with a surgical scalpel, electrical scalpel, or laser excision with a laser scalpel, e.g. a carbon dioxide laser, , Neodymium-YAG laser, or diode laser. The poorly fitting denture can be adapted to fit better (a "reline") or a new denture constructed. Alternatively, the section of flange that is sharp/over-extended can be smoothed and reduced with a drill.

There is no treatment, but because this is a benign condition with no serious clinical complications, prognosis is excellent.

Anti-tumour necrosis factor α antagonists (e.g. infliximab)

Dietary restriction of a particular suspected or proven antigen may be involved in the management of OFG, such as cinnamon or benzoate-free diets.

If the causative factor persists, tissue will become more fibrous over time.

Some researchers suggest that HGF is transmitted as a Mendelian trait since both autosomal dominant and autosomal recessive transmission has been reported since the early 1970s. (SOURCE 1) In more recent scientific literature, there is evidence in which pedigree analyses confirm autosomal dominant, autosomal recessive or even as X-linked inherited cases of the HGF trait.

In 2002, researchers described the SOS1 gene and proved for the first time that a single-nucleotide–insertion mutation of the SOS1 gene on codon 1083 is the preliminary cause of HGF1 in humans. (Source 1) Later on in 2010, there was a case study done on a 16-year-old male with severe gingival overgrowth, almost covering all teeth. Researchers approached this issue with periodontics - a partial gingivectomy and flap surgery. This case study concluded that surgery followed by regular follow-ups is a good way to treat HGF despite the fact that the risks of re-occurrence of the condition remain high.

Even more recently, a study was done in 2013 on a family that showed history of autosomal recessive inheritance of HGF. The study did not dismiss the return of HGF after treatment but did claim that general surgical intervention after scaling and root planning of teeth supplemented with good oral hygiene is good enough to prevent the re-occurrence of HGF. This case study also acknowledged how HGF can be part of a multi-system syndrome associated with disorders such as Zimmermann Laband syndrome (ear, nose, bone, and nail defects with hepatosplenomegaly), Rutherford syndrome (microphthalmia, mental retardation, athetosis, and hypopigmentation), Murray-Puretic Drescher syndrome and Ramon syndrome.

The following can occur if left untreated:

- Too much gingiva exposure

- Oral morbidity

- Chronic infection of areas between the gums and teeth, or at the gum line

- various degrees of Periodontitis - most likely due to the inability and difficulty of keeping the gingival margin and surrounding tissue clean due to the overgrowth

- Improper tooth eruption and/or complete prevention of tooth eruption as a result of too much gingiva exposure

- Systemic every-day troubles including functional and aesthetic problems of the mouth

- Malocclusion

OFG is uncommon, but the incidence is increasing. The disease usually presents in adolescence or young adulthood. It may occur in either sex, but males are slightly more commonly affected.

If there is persistent continuation of inflammation and bleeding, a prescription of antiplaque rinse would be useful.

Treatment options include antibiotic therapy (not a permanent solution), endodontic (root canal) therapy, or extraction.

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.

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.

Periapical periodontitis of some form is a very common condition. The prevalence of periapical periodontitis is generally reported to vary according to age group, e.g. 33% in those aged 20–30, 40% in 30- to 40-year-olds, 48% in 40- to 50-year-olds, 57% in 50- to 60-year-olds and 62% in those over the age of 60. Most epidemiologic data has been generated in European countries, especially Scandinavia. Millions of root canal treatments are carried out in the United States each year, although the total number of root canal treatments is an imperfect indicator of the prevalence of periapical periodontitis, since not always is it performed due to the presence of periapacial periodontitis, and not all cases of asymptomatic periodontitis will be treated in this manner, either due to lack of patient attendance or watchful waiting.

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.

There are many possible causes of gingival bleeding. The main cause of gingival bleeding is the formation and accumulation of plaque at the gum line due to improper brushing and flossing of teeth. The hardened form of plaque is calculus. An advanced form of gingivitis as a result of formation of plaque is periodontitis. Other causes that can exacerbate gingival bleeding include:

- placement of new dentures

- tooth or gum infection

- diabetes mellitus

- idiopathic thrombocytopenic purpura

- leukemia

- malnutrition

- use of aspirin and anticoagulants(blood thinners) such as warfarin and heparin

- hormonal imbalances during puberty and pregnancy

- iron overload

Other less common causes are:

- vitamin C deficiency (scurvy) and vitamin K deficiency

- dengue fever

White sponge nevus (WSN, or white sponge naevus, Cannon's disease, hereditary leukokeratosis of mucosa, white sponge nevus of Cannon, familial white folded dysplasia, or oral epithelial nevus), is an autosomal dominant condition of the oral mucosa (the mucous membrane lining of the mouth). It is caused by a mutations in certain genes coding for keratin, which causes a defect in the normal process of keratinization of the mucosa. This results in lesions which are thick, white and velvety on the inside of the cheeks within the mouth. Usually, these lesions are present from birth or develop during childhood. The condition is entirely harmless, and no treatment is required.

Treatment includes irrigation and debridement of necrotic areas (areas of dead and/or dying gum tissue), oral hygiene instruction and the uses of mouth rinses and pain medication. If there is systemic involvement, then oral antibiotics may be given, such as metronidazole. As these diseases are often associated with systemic medical issues, proper management of the systemic disorders is appropriate.

Sub-antimicrobial doses of doxycycline (SDD) have been used to alter host response to the periodontal pathogens. This is believed to disrupt the action of matrix metalloproteinases and thus minimise host mediated tissue destruction.

"The adjunctive use of SDD with SRP is statistically more effective than SRP alone in reducing PD and in achieving CAL gain."

If cause-specific measures are insufficient, soft-tissue graft surgery may be used to create more gingiva. The tissue used may be autologous tissue from another site in the patient's mouth, or it can be freeze-dried tissue products or synthetic membranes. New research is focused on using stem cells to culture the patients' own gums to replace receded gums.

In 2016, interferon gamma/CXCL10 axis was hypothesized to be a target for treatments that reverse inflammation. Apremilast is undergoing investigation as a potential treatment .

There is no definitive cure for LS. Behavior change is part of treatment. The patient should minimize or preferably stop scratching LS-affected skin. Any scratching, stress or damage to the skin can worsen the disease. Scratching has been theorized to increase cancer risks. Furthermore the patient should wear comfortable clothes and avoid tight clothing, as it is a major factor in the severity of symptoms in some cases.

Topically applied corticosteroids to the LS-affected skin are the first-line treatment for lichen sclerosus in women and men, with strong evidence showing that they are "safe and effective" when appropriately applied, even over long courses of treatment, rarely causing serious adverse effects. They improve or suppress all symptoms for some time, which highly varies across patients, until it is required to use them again. Methylprednisolone aceponate has been used as a safe and effective corticosteroid for mild and moderate cases. For severe cases, it has been theorized that mometasone furoate might be safer and more effective than clobetasol.

Continuous usage of appropriate doses of topical corticosteroids is required to ensure symptoms stay relieved over the patient's life time. If continuously used, corticosteroids have been suggested to minimize the risk of cancer in various studies. In a prospective longitudinal cohort study of 507 women throughout 6 years, cancer occurred for 4.7% of patients who were only "partially compliant" with corticosteroid treatment, while it occurred in 0% of cases where they were "fully compliant". In a second study, of 129 patients, cancer occurred in 11% of patients, none of which were fully compliant with corticosteroid treatment. Both these studies however also said that a corticosteroid as powerful as clobetasol isn't necessary in most cases. In a prospective study of 83 patients, throughout 20 years, 8 patients developed cancer. 6 already had cancer at presentation and had not had treatment, while the other 2 weren't taking corticosteroids often enough. In all three studies, every single cancer case observed occurred in patients who weren't taking corticosteroids as often as the study recommended.

Continuous, abundant usage of emollients topically applied to the LS-affected skin is recommended to improve symptoms. They can supplement but not replace corticosteroid therapy. They can be used much more frequently than corticosteroids due to the extreme rarity of serious adverse effects. Appropriate lubrication should be used every time before and during sex in genital LS in order to avoid pain and worsening the disease. Some oils such as olive oil and coconut oil can be used to accomplish both the emollient and sexual lubrication function.

Recent studies have shown that topical calcineurin inhibitors such as tacrolimus can have an effect similar to corticosteroids, but its effects on cancer risks in LS are not conclusively known.

In males, it has been reported that circumcision can have positive effects, but does not necessarily prevent against further flares of the disease and does not protect against the possibility of cancer. Circumcision does not prevent or cure LS; in fact, "balanitis xerotica obliterans" in men was first reported as a condition affecting a set of circumcised men, by Stühmer in 1928.

Chemical antimicrobials may be used by the clinician to help reduce the bacterial load in the diseased pocket.

"Among the locally administered adjunctive antimicrobials, the most positive results occurred for tetracycline, minocycline, metronidazole, and chlorhexidine. Adjunctive local therapy generally reduced PD levels...Whether such improvements, even if statistically significant, are clinically meaningful remains a question."

Minocycline is typically delivered via slim syringe applicators.

Chlorhexidine impregnated chips are also available.

Hydrogen peroxide is a naturally occurring antimicrobial that can be delivered directly to the gingival sulcus or periodontal pocket using a custom formed medical device called a Perio Tray. [Title = Custom Tray Application of Peroxide Gel as an Adjunct to Scaling and Root Planing in the Treatment of Periodontitis:

A Randomized, Controlled Three-Month Clinical Trial J Clin Dent 2012;23:48–56.]

Hydrogen peroxide gel was demonstrated to be effective in controlling the bacteria biofilm [Subgingival Delivery of Oral Debriding Agents: A Proof of Concept J Clin Dent 2011;22:149–158] The research shows that a direct application of hydrogen peroxide gel killed virtually all of the bacterial biofilm, was directly and mathematically delivered up to 9mm into periodontal pockets.

Dental plaque accumulates at the surfaces when proper cleaning and maintaining is not done. There is inflammation due to the bacteria released from the toxins. calculus forms and if not removed, causes this disease.

Drug-related gingival hyperplasia is a cutaneous condition characterized by enlargement of the gums noted during the first year of drug treatment. There are three drug classes that are associated with this condition namely, anticonvulsants (such as phenyotoin and phenobartibal), calcium channel blocker (such as amlopidine, nifedipine and verapamil) and ciclosporin, an immunosuppressant Although the mechanism of drug related gingival hyperplasia is not well understood, some risk factors for the condition include the duration of drug use and poor oral hygiene. In most cases, alternative drugs are given, in order to avoid this side effect.
