Which surface of the tooth is closest to the cheek?

The surface of the tooth that is closest to the cheek is referred to as the buccal surface. In dental terminology, "buccal" relates specifically to the area of the oral cavity that is adjacent to the cheeks. This is especially relevant for the posterior teeth, such as molars and premolars, which are positioned towards the back of the mouth and have their buccal surfaces facing the cheeks.

Understanding the orientation of tooth surfaces is essential for dental professionals when discussing treatment, performing procedures, or documenting findings. The buccal surface is involved in interactions with the cheeks during chewing and speaking, making it a critical aspect of oral anatomy.

The labial surface pertains to the front teeth and is situated closest to the lips, while the lingual surface is oriented towards the tongue. The mesial surface describes the side of the tooth that is directed toward the midline of the dental arch. Each of these surfaces serves a distinct purpose and is crucial for various dental practices, but the buccal surface is the correct answer when identifying the area adjacent to the cheeks.
