Tooth numbering system

Tooth numbering system is used by dentists for uniquely identifying and referring to a specific tooth. Over the years, over 20 different teeth numbering systems have been developed. Today, we use the following FDI tooth numbering systems for the numbering of the teeth.

FDI World Dental Federation Two-Digit Notation (international)

This system developed by the Fédération Dentaire Internationale (FDI), World Dental Federation notation is also known as ISO-3950 notation. The human teeth are symmetrically arranged in the mouth. Each quadrant of the mouth has 8 different teeth that are mirrored horizontally and vertically to the other quadrants.

In the FDI (Fédération Dentaire Internationale) World Dental Federation notation each one of these 8 teeth is assigned a number from 1 to 8, starting from the center front tooth (central incisor) and moving backwards up to the third molar (number 8). Each quadrant is also assigned a number, from 1 to 4 for the adult (permanent) teeth or 5 to 8 for the baby (primary or deciduous) teeth.
Quadrant codes Tooth codes
Adult teeth
1 upper right
2 upper left
3 lower left
4 lower right
Baby teeth
5 upper right
6 upper left
7 lower left
8 lower right
1. central incisor
2. lateral incisors
3. canines
4.1st premolars
5. 2nd premolars
6. 1st molars
7. 2nd molars
8. 3rd molars

The combination of these two numbers (Quadrant code number & Tooth code number) specifies how are teeth numbered. This tooth numbering system is called, the Two-Digit World Dental Federation Notation or FDI notation system.

Orientation of the FDI two-digit tooth numbering chart is traditionally "dentist's view", i.e. patient's right corresponds to tooth chart's left side. The designations "left" and "right" on the chart, however, correspond to the patient's left and right, respectively.
