Gingival enlargement is designated as localized when it is limited to the gingiva adjacent to a single tooth or group of teeth, and generalized when it involves the gingiva throughout the mouth. It is also designated as marginal when confined to the marginal gingiva, and papillary when confined to the interdental papilla.

The degree of gingival enlargement can be scored as follows: Grade 0 indicates no signs of gingival enlargement, Grade I indicates enlargement confined to interdental papilla, Grade II indicates enlargement involves papilla and marginal gingiva, and Grade III indicates enlargement covers three quarters or more of the crown.

Chronic inflammatory gingival enlargement is caused by prolonged exposure to dental plaque, poor oral hygiene, irritation by anatomic abnormalities, and improper restorative and orthodontic appliances.

Acute inflammatory gingival enlargement results from bacteria carried deep into the tissues when a foreign substance (e.g., toothbrush bristle, piece of apple core, lobster shell fragment) is forcefully embedded into the gingiva. The lesion is confined to the gingiva and should not be confused with periodontal or lateral abscesses.

Gingival enlargement is a well-known consequence of the administration of some anticonvulsants, immunosuppressants, and calcium channel blockers. The first drug-induced gingival enlargements reported were those produced by phenytoin (Dilantin). Other anticonvulsants that have the same side effect are the succinimides (ethosuximide [Zarontin], methsuximide [Celontin]) and valproic acid (Depakene).

Drug-induced enlargement may occur in mouths with little or no plaque, and it may be absent in mouths with abundant deposits. However, some investigators believe that inflammation is a prerequisite for development of the enlargement, which therefore could be prevented by plaque removal and fastidious oral hygiene.

Dilantin is a hydantoin that was introduced for the treatment of all forms of epilepsy, except petit mal seizures. Its relationship with gingival enlargement was reported shortly thereafter. Gingival enlargement occurs in about 50% of patients receiving the drug, although different authors have reported incidences from 3% to 5%. It occurs more often in younger patients.

Gingival enlargement caused by anticonvulsants starts as a painless, beadlike enlargement of the interdental papilla that then extends to the facial and lingual gingival margins. As the condition progresses, the marginal and papillary enlargements unite, and they may develop into a massive tissue fold that covers a considerable portion of the crowns; this may interfere with occlusion.
