💡Most of us believe that bones are the hardest substance in the human body, but actually, its our tooth enamel!
Teeth are made of three layers:
🦷 Enamel,
🦷 Dentine &
🦷 Nerves.
▫️The outer layer is the enamel and enamel is mainly made of minerals.
▫️In fact, almost 96 % of the enamel is minerals and yes, it’s harder than bone but don’t test it on bottle caps- it can be damaged by metal or glass.
