�Fibrous gingival hyperplasia, also known as gingival overgrowth, is
characterized by an increase in the size of the gingival tissue due to an
excessive accumulation of collagen and other extracellular matrix components.
This condition can be caused by various factors, including certain medications
(like anticonvulsants, calcium channel blockers, and immunosuppressants),
hormonal changes, or chronic inflammation.
