Do Rats Gnaw Concrete and Other Hard Materials?
Rats possess incisors that erupt continuously throughout life. The growth rate averages 0.2 mm per day, driven by stem cells in the dental papilla. This perpetual eruption compensates for wear caused by gnawing. The enamel of the upper incisors is limited to the front edge, while the dentin extends backward.. Date latest changes:
