The structure of the squirrel’s enamel and the cementum look similar to human teeth. Even their molars also look like ours. Also, the roots are identical to human teeth. Though, squirrels’ incisors look different from molars and cheek teeth because they have to grow them very fast to keep them according to their diet.
