Teeth are a unique part of our body that allow us to enjoy food—but is that all?
**Fact 1** – 99% of the calcium in our body is stored in our teeth. Tooth enamel consists mainly of calcium phosphate, known as hydroxyapatite, the hardest tissue in the body—even tougher than bone. This strength helps protect teeth from acids in the mouth. Under the right conditions, hydroxyapatite can repair itself after acid exposure.
*Maintaining calcium levels throughout life is key to healthy teeth. This means focusing on calcium-rich foods like milk, yogurt, and cheese (the best sources), as well as salmon, oysters, dried beans, and asparagus.*

**Fact 2** – Tooth enamel lasts 50-60 years. Enamel acts as a protective shield for teeth, consisting of up to 97% inorganic minerals, making it the hardest tissue in the body. Damaged enamel leads to tooth decay, so proper enamel care is a crucial part of oral hygiene.
**Fact 3** – Plaque contains 300 types of bacteria. While most are harmless, a small fraction can cause tooth or gum disease. Regular dental visits help control plaque bacteria and catch problems early. See a dentist at the first sign of gum issues, like bleeding during brushing.

**Fact 4** – Wisdom teeth appear in 92% of adults, but 25% never erupt. They can emerge at any age—the oldest recorded case was at 94.
**Fact 5** – A knocked-out tooth can be reinserted into the gum, but only if done within five minutes of loss. Saving the tooth still requires seeing a specialist within 30 minutes.
