Shark teeth are covered in fluoride, making them cavity-resistant. One 2012 study published in the Journal of Structural Biology found that sharks’ enamel is made up of a chemical called fluoroapatite, which is resistant to acid produced by bacteria.

This, combined with the fact that most sharks replace their teeth throughout their lives, means that sharks have excellent dental health.
