What is the Primary Teeth Numbering System in the USA?   

The primary teeth numbering system which is also known as the universal numbering system for primary teeth, uses letters A to T to designate each tooth. 

The letters are assigned sequentially, starting from the upper right second molar (A) and progressing to the upper left second molar (J), then to the lower left second molar (K), and finally to the lower right second molar (T). This system provides a standardized and universally understood method for identifying primary teeth during dental examinations and treatments.

How Do You Count Your Teeth?
