All rodents have a pair of upper and a pair of lower teeth called incisors. Unlike our teeth, these incisors don’t have roots, and they never stop growing! To keep these teeth from growing into their brains, rodents grind their teeth against each other. This friction is similar to using a grindstone to sharpen a knife.
How fast do rat teeth grow?
The incisors of rodents are continuously growing and wearing structures that are renewed every 40 to 50 d. Insufficient wear of the rodent incisors often results in an abnormal occlusal wear pattern and rapid tooth elongation. Unopposed, continuously growing incisors can erupt as much as 1 mm daily.
Do rats teeth continue to grow?
Rodent dentition Rodents have open-rooted dentition, meaning that their teeth grow continuously throughout their lives. The incisors, which are specialized for gnawing, continue to grow and curve.
