Dr Dental, How Beaver’s Teeth May Help Us
Beavers may show us the way to improve our own tooth enamel
Beavers don’t brush their teeth or drink fluoridated water, but a new study reports beavers do have protection against tooth decay built into the chemical structure of their teeth: iron. This pigmented enamel, the researchers found, is both harder and more resistant to acid than regular enamel, including that treated with fluoride.
