Mammals chew their food which requires a set of firmly attached, strong teeth and a "full" tooth row without gaps. The manatees have no incisor or canine teeth, just a set of cheek teeth, which are not clearly differentiated into molars and premolars. These teeth are continuously replaced throughout their life with new teeth growing at the rear ...
However, some mammals' teeth do develop differently than humans'. In mice, WNT signals are required for the initiation of tooth development. [9] [10] Rodents' teeth continually grow, forcing them to wear down their teeth by gnawing on various materials. [11] If rodents are prevented from gnawing, their teeth eventually puncture the roofs of ...
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. These teeth grow or erupt continuously.

As rodents, mice must gnaw to keep their incisors from growing too long. Overgrown teeth can cause occlusion (blockage) of the mouth, which in extreme cases can lead to starvation. Hard foodstuffs, small pieces of wood or specially prepared blocks can suit this purpose, although some mice can grind their teeth together to
In mammals with tribosphenic teeth, the protocone slides into the talonid basin on the lower teeth in order to grind and crush food. Often the largest cusp in the upper molar, though some insectivorous mammals reduce it substantially. Paracone: A major cusp outwards from the protocone and in front of the metacone.
Being rodents, as their teeth grow constantly (as do their nails, like humans), they routinely gnaw on things, lest their teeth become too large for their jaw (a common problem in rodents). [citation needed] Guinea pigs chew on cloth, paper, plastic, and rubber if available. Guinea pig owners may "Guinea Pig proof" their household, especially ...
