We know that our teeth are largely composed of a mineral and it is softer than that found in sharks. But, lemme tell you something: our teeth are as tough as shark’s. According to a research, the enameloid coating on shark teeth is no harder than that of the enamel on a human wisdom tooth. So, next time you’re bitten by a shark, fight! Bite it back, okay?
The truth is, our teeth surfaces aren’t pure mineral. They are made of mineral crystals which bound together with proteins so that the material doesn’t shatter under a sudden impact. Pretty tough, huh?
