Which term describes a tooth with two high points on the chewing surface?

• A. Bridge
• B. Buccal
• C. Bicupsid
• D. Calculus

Answer: (C)

Two high points on the chewing surface means the tooth has two cusps. In dental anatomy, a cusp is a raised point on the occlusal surface, and a tooth with two cusps is called a bicuspid (premolar). Premolars typically have two cusps, while molars have three or more and canines have a single cusp. The other terms don’t describe tooth shape: a bridge is a replacement tooth, buccal refers to the cheek-side surface, and calculus is tartar buildup.
