Cervix The rounded portion of the neck just below the crown
Enamel The hard, outer layer of the tooth that covers the crown and protects the tooth from damage

Pulp The innermost layer of the tooth that contains nerves and blood vessels

Cingulum The rounded bump on the lingual (tongue) side of the crown near the incisal edge
Fossa A shallow depression on the occlusal (chewing) surface of a molar
Tubercle A small bump on the occlusal surface of a molar
Ridge A raised portion on the occlusal surface of a molar
Contact Point The point at which two teeth touch when the jaw is closed
Margin The edge of a filling or restoration that is closest to the tooth’s pulp
Line Angle The junction between the gingival (gum) margin and the incisal or occlusal edge of a tooth
Facial Surface The front or cheek-facing surface of a tooth
Lingual Surface The tongue-facing surface of a tooth
Buccal Surface The cheek-facing surface of a tooth
Apical Foramen The opening at the end of the root through which nerves and blood vessels enter and exit the pulp
Root Canal The space within the root of a tooth that contains the pulp and root canals
Crown Margin The edge of a dental crown that is closest to the gum tissue
