What is the Labial surface of the teeth?

Face surface of posterior teeth
Facial surface of anterior teeth towards the lips
Surface of the tooth towards tongue
Surface of the tooth away from midline

The correct answer is: Facial surface of anterior teeth towards the lips

The labial surface of the teeth refers specifically to the facial surface of anterior teeth that faces the lips. This terminology is often used in dental contexts to differentiate between various surfaces of the teeth based on their anatomical positions. Anterior teeth, which include the incisors and canines, have this labial surface that is crucial for aesthetic considerations, as it's the part of the tooth visible when a person smiles or speaks. Understanding this terminology is important for dental professionals when discussing treatments, evaluations, and patient care. The other choices pertain to different surfaces of the teeth: the face surface of posterior teeth relates to the occlusal surfaces of molars and premolars; the surface of the tooth towards the tongue refers to the lingual surface; and the surface away from midline describes the distal surface, which is relevant in terms of tooth alignment and spacing but does not apply to the labial surface specifically. Thus, recognizing the correct definition of the labial surface helps clarify discussions around anterior teeth alignment and cosmetic dentistry.
