In order to do the tough job of biting and chewing your food, your teeth need to be incredibly strong. Your incisors use between 30-50 pounds to cut and tear your food while your molars exert around 200 pounds of pressure for chewing.
The part of the tooth above the gum line is called the crown. It is coated with a substance called enamel. Enamel is made of calcium and phosphorous, and is the hardest substance in the body. It is perfect for protecting the teeth as they bite and chew.
A tooth has one to three roots depending on its size and how much force it uses. Below the enamel of the tooth, the root is covered with cementum which is not as strong as enamel, and is vulnerable to decay if it is exposed by a receding gum line.
There are two types of tissues within the tooth itself, the dentin and pulp. The layer of dentin is found between the enamel and the pulp. Pulp is soft material that contains the nerves and blood vessels that keep the tooth alive, and is found at the center of the tooth.
