Study On Beaver Tooth Enamel Could Lead To Better Understanding Of Human Tooth Decay.
The Phys (2/13) reports that researchers at Northwestern University discovered in a recent study that beaver teeth “have protection against tooth decay built into the chemical structure of their teeth: iron.” Indeed, the researchers found that the pigmented beaver enamel is “both harder and more resistant to acid than” human enamel, including human enamel treated with fluoride. The article reports that the “discovery is among others that could lead to a better understanding of human tooth decay, earlier detection of the disease and improving on current fluoride treatments.”
