Tooth Numbering in other Species

Landmarks

Using definite landmarks we can number animals with less teeth, such as domestic cats, horses and rabbits.

The central incisor is always 01 and the following incisors are 02 and 03.

The canines are always 04.

The premolars are 05 to 08 and the last premolar is always 08.

The first molar is always 09 and the following molars are 10 and 11.

Domestic Cat

In cats, where tooth numbers are reduced, the use of the carnassials as landmarks will help considerably. The upper carnassials in carnivores are always the last premolars, which are 108 and 208. The lower carnassials in carnivores are always the first molars, 309 and 409.
