Are your teeth stronger than a knife?

The apatite group of minerals scores a five on the Mohs hardness scale; which makes enamel the hardest biological material. Tooth enamel is harder than steel, but a lot more brittle. So you can't scratch your enamel on metal cutlery but you can chip it by trying to open a beer bottle with your teeth.

Avoiding a Shattering Experience

Actually, teeth are able to resist a compressive force of about 30,000 pounds.

Are teeth harder than diamonds?

Just how hard is tooth enamel? It is, in fact, the human body's hardest substance. Using the scale of mineral hardness developed by German mineralogist Frederich Mohs in 1812, tooth enamel ranked 5 out of the 1-10 values. Diamonds ranked 10 (hardest) and plaster of Paris ranked only 2 on the Moh's scale.

Whats stronger femur or teeth?

Some people say that our leg bone, the femur, is the hardest part of our body. But that's only because the femur is bigger than our teeth. Pound for pound, enamel is the champ.

Humans can only grow two sets of teeth, baby and adult teeth, because of how they evolved over 300 million years ago.

Are human teeth as strong as sharks?

Though composed of different materials, the chompers of both species are equally tough. Don't feel inadequate. Even though your teeth are largely composed of a mineral softer than that found in sharks, new tests reported in the Journal of Structural Biology suggest that they're just as tough.

Can we crush our own teeth?

Technically, you can pull your own teeth, but it is never a good idea. There are many things that can cause the need to have a tooth removed. Cracks, advanced tooth decay, infections, and more can result in the need for an extraction.
