Occular Surface

Occular Surface is the chewing surface of a primary or secondary posterior tooth in one arch that makes contact or near contact with the corresponding surface of a tooth in the opposite arch. Also called masticatory surface. “Occlusal” refers to the surface of the tooth that is used for chewing or grinding. Overall, there are five surfaces to each tooth: Occlusal. Mesial: forward or front, Distal: behind towards the back of the mouth, Buccal: the tooth surface which is next to your cheeks, Lingual: the tooth surface next to your tongue. The surfaces and edges of your teeth go by different names. As the National Examining Board for Dental Nurses points out, there are nine different tooth surfaces, two of which are essential to chewing: the incisal surface and the occlusal surface. The incisal surface is the biting edge on the canines and incisors, near the front of your mouth, while the occlusal is the biting edge, or the top of, your molars and premolars.
