Why do rats and mice have such strong teeth?
MammalsDentition
Quick Answer
Rats and mice have strong teeth because their incisors grow continuously and must withstand constant gnawing. The enamel is especially hard and the teeth self-sharpen as they wear unevenly.
The Full Story
Rodents are defined by a pair of large upper and lower incisors that never stop growing. These teeth are adapted for gnawing seeds, bark, roots and many other hard materials. The front surface contains harder enamel than the back, so wear creates a chisel-like edge that stays sharp. Because the teeth keep growing, rodents must continually chew to prevent overgrowth.
Key Facts
1.Rodent incisors grow throughout life
2.Uneven enamel wear creates a self-sharpening edge
3.Gnawing prevents dangerous overgrowth
