The dental formula for primary teeth in humans is 2.1.0.2 2.1.0.2. In the primary set of teeth, in addition to the canines there are two types of incisors—centrals and laterals—and two types of molars—first and second. All primary teeth are normally later replaced with their permanent counterparts.
This is seen, for example, throughout The Cambridge Dictionary of Human Biology and Evolution. The greatest number of teeth in any known placental land mammal [specify] was 48, with a formula of 3.1.5.3 3.1.5.3. [9] However, no living placental mammal has this number. In extant placental mammals, the maximum dental formula is 3.1.4.3 3.1.4.3 ...
Today, humans possess 32 permanent teeth with a dental formula of 2.1.2.3 2.1.2.3. [1] This breaks down to two pairs of incisors, one pair of canines, two pairs of premolars, and three pairs of molars on each jaw. [1]
The dental formula of humans is: 2.1.2.3 2.1.2.3. Humans have proportionately shorter palates and much smaller teeth than other primates. They are the only primates to have short, relatively flush canine teeth. Humans have characteristically crowded teeth, with gaps from lost teeth usually closing up quickly in young individuals.
The dental formula is 2.1.2.3 2.1.2.3. Human teeth and jaws are markedly smaller relative to body size compared to those of other apes. This may be an adaptation not only to the extensive use of tools, which has supplanted the role of jaws in hunting and fighting, but also to eating cooked food since the end of the Pleistocene.

Rabbits have a dental formula of 2.0.3.3 1.0.2.2. There are no canines. Three to four millimeters of tooth is worn away by incisors every week, whereas the posterior teeth require a month to wear away the same amount. [3] Anatomy of rabbit teeth. The incisors and cheek teeth of rabbits are called aradicular hypsodont teeth.
