Anatomy of rabbit teeth. The incisors and cheek teeth of rabbits are called aradicular hypsodont teeth. Aradicular teeth never form a true root with an apex, and hypsodont teeth have a high crown to root ratio (providing more room for wear and tear). [4] This is sometimes referred to as an elodont dentition, meaning ever-growing.
Rather than inheriting their early hominid ancestors’ large sized molars, human molars evolved significantly, reducing instead to a size more similar to their front teeth. Contrary to megadont hominins’ dominant second molars, modern humans’ first molar is the largest, and their mandibles can rarely fit a third molar.
The dashes (-) in the formula are likewise not mathematical operators, but spacers, meaning "to": for instance the human formula is 2.1.2.2-3 2.1.2.2-3 meaning that people may have 2 or 3 molars on each side of each jaw. 'd' denotes deciduous teeth (i.e. milk or baby teeth); lower case also indicates temporary teeth.

Malocclusion: Rabbit teeth are open-rooted and continue to grow throughout their lives, which is why they need constant abrasion. Since tooth enamel is the hardest substance in the body and much harder than anything a rabbit could chew, wearing down the teeth can only happen through chewing movements, i.e., by the teeth wearing down each other.
General patterns of dental morphological evolution throughout human evolution include a reduction in facial prognathism, the presence of a Y5 cusp pattern, the formation of a parabolic palate and the loss of the diastema. Human teeth are made of dentin and are covered by enamel in the areas that are exposed. [2]
