The surface of a tooth nearest the midline is called the...

Explanation:
The surface nearest the midline is the mesial surface. The midline runs down the center of the face, dividing the mouth into left and right halves, so mesial means toward that line. The opposite surface is distal, which faces away from the midline toward the back of the mouth. Other directional surfaces include buccal (toward the cheek), lingual (toward the tongue), and palatal (toward the palate, on upper teeth). The chewing surface on back teeth is called occlusal, while the cutting edge on front teeth is the incisal surface.
