Have you ever wondered what tooth your dentist is talking about when they say you have a cavity on #3? Tooth number 1 is the tooth farthest back on the upper right. Numbering continues along the upper teeth toward the front and across to the tooth farthest back on the upper left side, number 16. The numbers continue by dropping down to the lower left, number 17 and across to the tooth farthest back on the lower right, number 32. Refer to the tooth chart on the right if you have any questions. – from Kate B. (Business Team) |  |
