Dental Assistant Terminology Practice Test

The cutting edge on the front teeth is called the incisal edge. This edge is the biting or incising edge of the centrals and laterals, formed by the incisal ridges of these anterior teeth and used for cutting food. The other terms describe different surfaces or areas: the occlusal surface is the chewing surface on the back teeth, the buccal surface faces the cheek, and the lingual surface faces the tongue.
