Teeth are a unique organ that allows us to savor food and… is that all?
**Fact 1** – 99% of the calcium in our bodies is stored in our teeth. Tooth enamel is primarily made of calcium phosphate molecules called hydroxyapatite, the hardest tissue in the body—even tougher than bone. This durability helps teeth resist acids in the mouth. Under the right conditions, hydroxyapatite can even repair itself after acid exposure.
*Maintaining adequate calcium levels throughout life supports dental health. Focus on calcium-rich foods like milk, yogurt, and cheese—excellent sources—as well as salmon, oysters, dried beans, and asparagus.*

**Fact 2** – Tooth enamel lasts about 50-60 years. Serving as a protective shield, enamel is the body’s hardest tissue, composed of up to 97% inorganic material. Once damaged, the underlying tooth structures deteriorate, making proper enamel care a cornerstone of oral hygiene.
**Fact 3** – Plaque hosts 300 types of bacteria. While most are harmless, a small fraction can harm teeth or gums. Regular dental check-ups help manage bacterial levels and catch issues early. See a dentist immediately if gums bleed during brushing, a possible sign of disease.

**Fact 4** – Wisdom teeth appear in 92% of adults, but 25% never erupt. These teeth can emerge at any age—even as late as 94, the oldest recorded case.
**Fact 5** – A knocked-out tooth may survive if reinserted within 5 minutes. However, professional care within 30 minutes is crucial for saving it.
