Gingiva or gums surround the teeth and provide a seal around them.
Healthy gingiva appears in coral pink color, but may contain melanin pigment.
Gingiva is divided into free gingiva, attached gingiva and interdental papilla.
Free gingiva is terminal edge of gingiva surrounding the teeth in collar like fashion.
Attached gingiva is continuous with free gingiva and it is firm, resilient tightly bound to the underlying alveolar bone.
Interdental papilla is in pyramidal shape and it occupies the interproximal space beneath the area of tooth contact.

Gingival overgrowth also called as gingival hyperplasia or gingival hypertrophy or hypertrophic gingivitis. Gingival overgrowth is the enlargement of attached gingiva due to increased number of cells.
Gingival overgrowth can be initiated by factors such as mouth breathing, irritations along the neck of the tooth or hormonal changes such as those at puberty.
