Tooth

body · animals · super hard

Harder than bone. Teeth aren't made of bone! They're built from layers of special tissues, and the outer enamel is the hardest material your whole body makes.

Built to chew. Teeth break down food into smaller pieces so your body can digest it more easily.

More than munching. Many animals use their teeth to catch prey, defend themselves, or even gently carry their babies.

Hidden roots. The part you see is just the top. The roots reach down below and are covered and protected by your gums.
