💡 Trivia Your Teeth Are the Only Part of Your Body That Can't Heal Themselves

[Beatriz9]

Unlike your skin or bones, your teeth cannot repair themselves once they are damaged. This is because tooth enamel contains no living cells. Even a tiny crack or cavity will not naturally heal over time. That's why dentists use fillings instead of waiting for teeth to recover.

Tooth enamel is also the hardest substance in the human body. Once it's gone, your body cannot grow it back.
