Question: 1 / 400

Which surface of the tooth is closest to the cheeks?

Facial

Buccal

The buccal surface of a tooth refers to the side that is nearest to the cheeks. In dental terminology, "buccal" specifically indicates the surface that faces the inside of the cheeks, making it a critical term in describing the orientation of teeth in relation to oral structures.

The facial surface, while it can be close in meaning, encompasses not only the buccal surface but also the labial surface, which is the side facing the lips. Thus, while the facial surface is a broader term, the buccal surface specifically identifies the area nearest to the cheeks.

The lingual surface refers to the side of the tooth that faces the tongue, and the palatal surface is used to describe the area of the upper teeth that faces the palate. These surfaces are opposite the buccal surface, making them irrelevant to the question of which surface is closest to the cheeks.
