What is the Occusal Surface?
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.
Given that the occlusal surfaces play a big role in your everyday life, you're more likely to see wear and tear on them. Understanding how wear develops on the surface and what you can do to treat it will help you keep your teeth in great shape.
