Have you ever stopped to think about what your teeth are mad of? And what’s inside of them? How strong they are?
Teeth are lots more complicated that they appear on the outside. The art you can see – called the crown- is just the tip of the iceberg when it comes to your teeth. There are all sorts of things going on below the surface.
Although it looks like you can see a lot of your teeth, all you really see is the hard exterior known as the crown. The crown is covered with a super-hard, shiny substance called enamel. The enamel is like body armor for your teeth, protecting their inner parts from damage. How hard is enamel? In fact, the enamel on your teeth is the hardest substance in your body; it is even harder than your bones.
Underneath the enamel is another hard substance called dentin. Most of the tooth is made up of dentin. Dentin isn’t quite as hard as enamel, but it’s still quite hard and does a good job of protecting the innermost part of the tooth, called the pulp. Dentin is about as hard as your bones.
Now that you know a bit more about makes up your teeth and how strong our teeth are. However, Pacific dental group hope everyone take care of their teeth, although they are the strongest part in our body, but they are also very important and easy to destroy by bad bacteria.
