The tooth surface that is on the inside of the teeth is called ____.

Incisal surface
Lingual surface
Mesial surface
Occlusal surface

The correct answer is: Lingual surface

The inside surface of the teeth, facing the tongue, is called the lingual surface. This surface is named so because it is located towards the tongue or lingual side of the dental arch. The other options are incorrect because: - The incisal surface refers to the cutting edge of anterior teeth. - The mesial surface is the tooth surface that is closest to the midline of the dental arch. - The occlusal surface is the chewing surface of posterior teeth.
