Do you know how to designate / name your teeth according to the international standard?
The International Dental Federation (FDI) has established a diagram that assigns a number to each of our teeth. This makes it possible to precisely locate a tooth, and also to facilitate the documentation of care and the transmission of information between doctors, with insurance companies, etc.
This numbering is done
- by dividing the 2 arches (upper and lower) of the jaw into two quadrants each, numbered from 1 to 4 according to the model below
- Quadrants 1 (right) and 2 (left) for the upper arch
- Quadrants 3 (left) and 4 (right) for the lower arch
- by numbering the teeth of each quadrant from 1 to 8 starting from the middle of the mouth and all the way to the bottom, adding the number of the quadrant. The first number therefore corresponds to the quadrant concerned and the second number to the position of the tooth in relation to the center.
In children up to about 6 years of age, the quadrants are numbered from 5 to 8, and the teeth from 1 to 5.
