FDI Tooth Numbering System
The FDI dental notation is a two-digit tooth numbering system, widely used by dental professionals in many countries to easily identify teeth in a patient’s mouth. Developed by the Fédération Dentaire Internationale (FDI) World Dental Federation, this system is also referred to as the ISO 3950 notation.
The FDI chart takes a traditionally ‘dentist’s view’ with the patient’s right corresponding to the left of the chart. Left and right on the chart correspond to the patient’s left and right.
