Which term is the surface of the tooth toward the cheek or lips?

• A. Cavity
• B. Buccal
• C. Calculus
• D. Composite

Answer: (B)

Understanding dental surface terminology helps you describe where a tooth is oriented. The term buccal designates the surface that faces the cheek. It’s the standard label for the cheek-side surfaces, especially on posterior teeth. While labial specifically refers to the surface facing the lips (primarily on anterior teeth), buccal is the common term used for the cheek-facing side, and in many contexts it’s used to describe facial surfaces in general. So, for a surface toward the cheek (and, in broad usage, the facial aspect), buccal is the correct term. The other words describe something else entirely—cavity refers to decay, calculus to tartar buildup, and composite is a tooth-colored filling material.
