Rabbits dental makeup

Bunnies are heterodonts meaning that they have more than one type of tooth, four to be specific. They include Incisors, peg teeth, premolars, and molars, six of which are incisors, and 22 check teeth, as we shall expound further.

Bunnies are also hypsodonts, meaning their back teeth also have high crowns that help them chew a fibrous diet. Additionally, rabbits have elodont dentition, meaning that their teeth grow continuously throughout their life. Below are the four different types of rabbit teeth.

1. Incisors

Incisors are a rabbit’s front teeth, two on the lower and four on the upper side of their mouth. The incisors are chisel-like shaped prominent teeth used for cutting vegetation and cropping grass. Lastly, there is a diastema or gap that separates the incisors and premolars.


2. Peg Teeth

Peg teeth are normally positioned behind the upper incisors and they’re usually slightly smaller and less visible. Two peg teeth help align both the upper and lower sets of incisors.


3. Premolars

These sets of teeth are located behind the peg teeth. They’re normally six premolars on both the upper and low rabbit jaws, with the main function of crushing fibrous food.


4. Molars

Lastly, the last type of rabbit teeth is the molars, also known as their back teeth. This set has six molars on the lower jaw and four on the upper. Molars are used for grinding food since they are normally larger and wider.


Rabbit dental growth/ eruption

Rabbit teeth grow continuously throughout their life due to their open root structure also known as aradicular teeth. The dental eruption, therefore, helps replace worn-out teeth for constant chewing and grinding of food. Rabbit’s incisors (front teeth) mainly grow quicker than their back teeth (molars). In addition, their low teeth also tend to grow at a higher rate than their upper teeth.
