Enamel is so tough because it’s made of crystals — but those crystals are arranged like armor
Tooth enamel is built from millions of tightly packed hydroxyapatite crystals. But what makes it extraordinary is their interlocking, twisted pattern, which works like medieval chainmail armor — absorbing shocks and preventing fractures. This microscopic design is so advanced that engineers study enamel to create stronger body armor and aerospace materials.
