The tooth numbering continues by assigning teeth numbers descending to the lower left third molar (number 17) and follows the lower (mandibular) jaw up to the tooth farthest back on the bottom right side of the mouth (number 32).
Out of nowhere, he or she rattles off alpha-numeric jargon: 3MOD, 5DO, 13MFD and so on. The dentist is using a form of dental shorthand. Numbers represent teeth that have cavities or other problems. The upper right, third molar or wisdom tooth (this is the one farthest back in the mouth) is tooth number one. Tooth 16 is the upper left, third molar. Number 17 is the lower left, third molar. And 32 is the lower right, third molar.
