Tooth Enamel Is Harder Than Steel — But Can Still Break
Tooth enamel is the hardest substance in the human body—even harder than bone or steel on a relative scale. But unlike steel, enamel is brittle, meaning it can crack or chip from things like grinding or chewing ice.
💡 Tip: Once enamel is gone, it doesn’t grow back. Protect it with a soft-bristle brush and avoid acidic drinks.
