What does incisal mean?
Incisal is a technical dental adjective meaning relating to the cutting edge or biting surface of a tooth. It is especially associated with incisors, the broad front teeth used to cut food, although dental professionals may also use it for the opposing biting surfaces of other teeth. In examinations, restorations, orthodontics, and prosthodontics, the term distinguishes the functional cutting edges of teeth from surfaces that grind against one another. A sentence such as "the incisal edge was chipped" therefore identifies damage to the part of the tooth involved in biting or cutting. Incisal is not a general synonym for sharp or forceful; those meanings belong to words such as incisive. Its precision and specialist setting make it valuable in dental descriptions, diagrams, and clinical records, but unnecessary in ordinary speech when a simpler expression such as biting edge will do.
