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).
The universal numbering system, pictured above, identifies each tooth in a personâs mouth with an individual number. This system references all the teeth that should be in your mouth, so if you have wisdom teeth (or other teeth) which have been removed, those numbers still exist. # 1 is your upper right wisdom tooth. Each tooth then progresses up one number all the way across to the 3rd molar (wisdom tooth) on the left side of the mouth (# 16). #17 will be the lower left wisdom tooth, and counting clockwise, the last tooth will be #32, the lower right wisdom tooth.
