Which term describes the direction away from the midline?

Explanation:
Distal describes a direction away from the midline. The midline is the imaginary vertical line that divides the mouth into left and right halves, so distal points toward the back of the mouth, away from that center line. In contrast, mesial means toward the midline. Buccal and lingual refer to surfaces toward the cheek and toward the tongue, respectively, and aren’t about distance from the midline. So when you’re indicating a surface or direction away from the center, you’d use distal.
