Extreme strength observed in the teeth of limpets

Studying naturally occurring materials may aid in the development of new man-made composites for the dental industry. as well as many other industries that use high strength materials.

Excerpt from BBC: “Engineers in the UK have found that limpets’ teeth consist of the strongest biological material ever tested. Limpets use a tongue bristling with tiny teeth to scrape food off rocks and into their mouths, often swallowing particles of rock in the process. The teeth are made of a mineral-protein composite, which the researchers tested in tiny fragments in the laboratory. They found it was stronger than spider silk, as well as all but the very strongest of man-made materials.”

Beavers don’t brush their teeth, and they don’t drink fluoridated water, but a new study reports beavers do have protection against tooth decay built into the chemical structure of their teeth: iron.
