Tooth Names and Numbering
Dental team members should be familiar with tooth names and numbering. The Universal Numbering System (American System) is commonly used in the United States.
The numbers 1–32 are used to describe permanent teeth.
Tooth #1 is the upper right third molar also known as a wisdom tooth. The tooth in front of that tooth, the second molar is tooth #2. Continue counting each tooth until you reach the third molar on the upper left side, #16.
#17 is the third molar on the lower left side and continue counting all the way to the lower right third molar, #32.
The uppercase letters A through T are used for primary teeth identification.
A–J are the upper teeth with A being the second molar on the upper right and J being the second molar on the upper left.
K–T are on the bottom with K being the second molar on the left side and T being the second molar on the right side.
