Tooth Universal Numbering System

Tooth Universal Numbering System - © Attention Deficit Disorder Prosthetic Memory Program

Although it is named the “universal numbering system”, it is also called the “American system” as it is only used in the United States. The uppercase letters A through T are used for primary teeth and the numbers 1 - 32 are used for permanent teeth. The tooth designated “1” is the maxillary right third molar (“wisdom tooth”) and the count continues along the upper teeth to the left side. Then the count begins at the mandibular left third molar, designated number 17, and continues along the bottom teeth to the right side. Each tooth has a unique number or letter, allowing for easier use on keyboards.
