The hardest part of the human body is tooth enamel. It's the outer layer of your teeth and is made up of a mineral called hydroxyapatite, which is a very strong and hard material. In fact, tooth enamel is even harder than bone!
This hardness makes it well-suited to protect your teeth from the wear and tear of chewing. It's important to note that, even though enamel is very hard, it's also quite brittle and can be damaged by acidic foods and drinks, as well as by bacteria.
Here are some interesting facts about tooth enamel:
- Tooth enamel is the hardest substance in the human body. It's even harder than bone!
- Tooth enamel is made up of about 96% minerals. The rest is made up of water and organic materials.
- Tooth enamel is very resistant to acids. However, it can be damaged by acidic foods and drinks, such as soda and citrus fruits.
- Tooth enamel is not a living tissue. This means that once it's damaged, it can't repair itself.
It's important to take good care of your teeth and enamel by brushing and flossing regularly, and avoiding acidic foods and drinks.
