Introduction

Gingiva wrap around the neck of each tooth forming the gums. The gums are useful clinically in assessing health status of an animal.

Structure and Function of the Gingiva

Gingiva is mucosal tissue over alveolar bone. It has a stratified squamous epithelium, with some keratinisation. It resists friction of food during mastication by being tightly bound to the underlying bone. It recedes with age, exposing the cervical part of the tooth. It is usually salmon pink in healthy animals. A colour change indicates pathology.

Labiogingival groove

Labiogingival Groove Histology - Copyright RVC 2008

The labiogingival groove is the junction between the labial border and gingival line on the distal/medial surface of the incisor teeth.

Vasculature and Innervation of the Gingiva

The gingiva is supplied by the superior and inferior alveolar arteries.

There are blood vessels in the dental pulp cavity and a single branch in each major elevation of the crown.

Innervation is from the trigeminal nerve (CN V).

Canine

Some breeds of dog have dark gums, e.g. chow chow.
