Yes, it is once again everyone’s favorite week of the year: Shark Week<\/a>. For one week, every year, we humans become captivated by these living fossils that dart through the ocean water, instilling fear in even the most daring human. For the best, concise description of a shark’s life, we turn to Mr. Hooper<\/a> from the oceanographic institute in Jaws<\/a>: “what we are dealing with here is a perfect engine, an eating machine. It’s really a miracle of evolution. All this machine does is swim and eat and make little sharks, and that’s all.”<\/p>\n

Sharks and Dental Health<\/h2>\n

With all this eating, what happens to their teeth? Most of us know that shark’s not only have enormous, terrifying teeth, but that they constantly get replaced throughout life. No dentures for an old timer shark. What’s even more incredible, however, is that sharks, in spite of their voracious eating habits, do not develop cavities<\/a>.<\/p>\n

Humans develop cavities due to (for the most part) our love of sugar. And even if were aren’t eating glucose, our affinity for carbohydrates<\/a>\u00a0causes cavities as complex molecules are broken down into simple sugars that bacteria in our mouth use to make lactic acid<\/a>\u2014hence cavities. Sharks, of course, don’t have much access to sugar like us, which spares shark teeth the inconvenience of dental caries.<\/p>\n

Highly Evolved<\/h2>\n

But there’s another even more fascinating reason for sharks’ cavity-free mouths: their teeth seemed to be coated with fluoride!\u00a0According to\u00a0research published last year<\/a>\u00a0in the\u00a0Journal of Structural Biology<\/i><\/a>, at least two species of sharks\u2014makos<\/a> and tiger sharks<\/a>\u2014feature teeth whose outer coatings “contained one hundred percent fluoride.” Basically, sharks swim around with this permanent coating of toothpaste. This fluoride comes from fluorapatite<\/a>, which coats sharks’ teeth. It prevents cavities, but also is less-soluble in water than hydroxylapatite<\/a>\u2014the material that coats our teeth\u2014making their teeth perfectly suitable for their underwater life.\u00a0\u00a0The research focused only on these two species, but there’s good reason to believe that this biological feature may be extended to many other species.<\/p>\n

Will humans one day have the luxury of a natural coat of fluoride covering their teeth, or will we be slaves to the toothbrush forever? We can only hope that someday a mad scientist combine our genes with that of a shark so we too can eat without having a care in the world for getting dental cavities.<\/p>\n
