How strong are teeth?

Depends, the mineral portion of your enamel is hydroxyapatite which is the hardest material made in your body. This is also found in bone but enamel is made of 95% hydroxyapatite. Being this hard also makes them brittle so don't open your beer with your teeth. Surprisingly your teeth do get stronger as you get older because fluoride replaces calcium making them harder, as long as you brush and floss.
