Universal Numbering System. Tooth number 1 is the tooth farthest back on the right side of your mouth in the upper (maxillary) jaw. Numbering continues along your upper teeth toward the front and across to the tooth farthest back on the top left side (which is number 16).
Teeth 1 and 2 are the incisors. 3 is the canine (cuspid). 4 and 5 are bicuspids. 6, 7, and 8 are molars. The 6 is your 6 year molar, the 7 your 12 year molar, and the 8 is your wisdom tooth. Identifying a tooth is easy. All tooth numbers are a combination of the quadrant and then the tooth number. For example, tooth number 14 would be the upper right bicuspid. Tooth 21 is the first incisor on the top left.
