Question

why do mice have sharp
incisors​

Answer 1

Explanation:

Rodents have enlarged chewing muscles that allow their jaw to work in a vertical, forward and backward motion. Only the front surface of the incisors has enamel, the back is softer dentine. This arrangement allows the continuously growing incisors to remain sharp as they are worn off.
