Incisor tooth. Light micrograph of a section through an incisor. Incisors are located near the front of the mouth and are used for cutting through tough foods,particularly meat. At the centre of the tooth (white oval) is the pulp cavity,containing specialised connective tissue and sensory nerve fibres (dental pulp). The bulk of the tooth is dentine (peach at tip,pink at root),a mineralised tissue similar to bone. Surrounding the dentine is enamel (thin brown layer at top),the hardest substance in the body. The tooth is embedded in the periodontal membrane (pale purple) and alveolar bone (purple). At the surface of the gum is the gingiva (dark pink),the soft tissue that covers the alveolar bone | |
