Teeth Numbering
Teeth numbering charts will help you identifying each tooth.
FDI Two-Digit Notation
A committee of the American Dental Association (ADA) recommended the use of the Palmer notation method in 1947. Since this method required the use of symbols, its use was difficult on keyboards. As a result, the association officially supported the universal system in 1968. The World Health Organization and the Federation Dentaireofficially uses the two-digit numbering system of the FDI system.
Universal Teeth Numbering System
The Universal Tooth Numbering System is used primarily by most general dentists in the United States. It is a simplified method of identifying teeth that is approved and adopted by the American Dental Association.
In the Universal Tooth Numbering System tooth number 1 is the patient's upper right third molar, on the right side of the mouth in the upper jaw. Numbering of teeth continues along the upper teeth toward the front and across to the last molar tooth back on the top left side to number 16. The tooth numbering continues by assigning teeth numbers descending to the lower left third molar to number 17, and follows the lower jaw up to the tooth farthest back on the bottom right side of the mouth to number 32. All teeth that should be there are numbered, including those teeth that have been removed for any reason or have not erupted yet (e.g. wisdom teeth).
