No teeth cleaning needed: Crocodiles shed old teeth, grow new ones
Having one of the most powerful bites in the animal kingdom, crocodiles must be able to bite hard to eat their food such as turtles, wildebeest and other large prey. Now, researchers have found that crocodiles — and even their plant-eating ancestors — had thin tooth enamel, a trait that is in stark contrast to humans and other hard-biting species. These findings could suggest new approaches for dealing with people’s teeth.
