Tooth Enamel

teeth · protection · minerals

Harder than bone. Tooth enamel is one of the hardest substances in your entire body, even tougher than the bone underneath it. It's packed with minerals that make it incredibly strong and durable.

Shield against damage. Enamel covers the crown of your tooth, which is the part you can see when you smile. It protects the softer layers underneath called dentin, pulp, and cementum from getting hurt or infected.

Acid is the enemy. Acidic foods and drinks like soda, lemonade, and citrus fruits can slowly wear down your enamel over time. Once enamel wears away, it doesn't grow back, so protecting it is super important.

Naturally white and shiny. Healthy enamel is bright white to off-white and has a beautiful shine. This is why dentists say brushing and flossing help keep your smile sparkling.

Not just for humans. Many animals have tooth enamel too, including fish and other creatures. It's one of nature's cleverest inventions for keeping teeth strong.
