F D I M L
Schematic view from above. Mesial is drawn left and distal right on every tooth; on a real chart, which side faces the midline depends on the quadrant.
  • M Mesial — The side facing the front of the mouth, toward the midline.
  • D Distal — The side facing the back of the mouth, away from the midline.
  • F Facial — The lip or cheek side. On front teeth this is also called labial.
  • L Lingual — The tongue side. On upper teeth it is also called palatal.
  • I Incisal — The biting edge. Incisors and canines only.
