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).
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.
