The Tooth About Sharks
For those of you patiently waiting for the premier of Sharknado Part 2, we’ve got a little shark trivia to keep you going in the meantime.
Did you know that sharks don’t need to brush their teeth? Okay, technically they can’t brush them. But even if they could, they wouldn’t have to.
According to a study in the Journal of Structural Biology, at least two shark species contain teeth that are actually 100% coated with a substance called flouroapatite (fluorinated calcium phosphate) that’s resistant to acid-producing bacteria. This substance is similar to the active ingredient we humans find in drinking water, toothpaste and mouthwash.
Sharks’ teeth have their own cavity-fighting fluoride. But we don’t. So let’s keep up with the fluoride, please, by drinking fluoridated water and using toothpaste and mouthwash with fluoride.
And parents, be sure to ask us about dental sealants that can be applied to your children’s molars (chewing teeth) to help keep them cavity free.
To children of all ages: Brush, brush, brush!
