The surface of the tooth opposite the labial surface is known as?

The surface of the tooth opposite the labial surface is known as the lingual surface. The labial surface refers to the outer surface of the front teeth that faces the lips, typically associated with incisors and canines. Conversely, the lingual surface is the inner surface of those teeth, which faces the tongue. This terminology is essential for accurately communicating the orientation and location of dental issues or procedures.

In small animal dentistry, understanding these terms is crucial for procedures such as cleanings, examinations, and treatments. The distinction between labial and lingual surfaces helps ensure the correct identification of areas for interventions, thus maintaining dental health for small animals.
