Which term denotes the tooth surface next to the lips?

Explanation:
Labial denotes the tooth surface that faces the lips. On the front teeth (incisors and canines), this surface is toward the lips and is what you see when someone smiles. The corresponding surface toward the cheek is buccal (for posterior teeth), the surface toward the tongue is lingual, and the incisal edge is the biting edge of the front teeth. So the surface next to the lips is labial.
