An
increase in size and thickness of the soft tissue which surrounds a tooth
results in overgrowth of the gums (gingiva).
Frequently,
the gums grow large enough to completely cover the teeth.
What causes gingival hyperplasia?
An exaggerated
reaction by the gingiva to bacteria and tartar on the teeth. Usually periodontal diseases cause
gingiva to recede. Boxers have the opposite reaction.
Certain
medications used to treat seizures, allergies, infection or high blood
pressure can cause gingival hyperplasia. This is usually reversible if
the medications can be stopped.
