tooth numbering system

tooth numbering system

A system used to identify teeth. The American Dental Association recognizes two systems: one used in the U.S. (the “universal/national system”), and the other in other countries (the “international standards organization system”).

tooth numbering system international standards organization

An internationally recognized system of tooth numbering in which teeth in each quadrant are identified by numbers 1 through 8. A second number indicates the quadrant. Quadrant 1 is the maxillary right quadrant; quadrant 2 is the maxillary left quadrant; quadrant 3 is the mandibular left quadrant; and quadrant 4 is the mandibular right quadrant. Tooth number 13, for example, indicates the maxillary right quadrant and the canine tooth.

tooth numbering system universal/national

A system of tooth numbering that uses numbers 1 through 32 to identify the permanent teeth. Tooth number 1 is the maxillary right third molar. Tooth number 17 is the mandibular left third molar. Primary teeth are identified similarly, with the letters A through T.
