Dentists use something called “dental notation,” which is also called the “ANSI/ADA/ISO Tooth Numbering System,” to talk about or write about teeth. It is a way to show in a picture how many teeth a person has and how they are arranged.

The Palmer notation method, the universal numbering system, and the FDI global dental federation notation (ANSI/ADA/ISO Tooth Numbering System) are the three most common dental notations.
