Some Things To Know About Teeth
Teeth are hard structures that are found in the upper and lower jaws that facilitate eating and speaking. There are several types of teeth, and they have different tasks. In humans, the front teeth are used for biting and the back teeth are used for chewing food. Teeth in the upper jaw work with teeth in the lower jaw to cut, tear and grind the food. Digestion begins in the mouth, and teeth are an essential part of this process. Teeth also help support the muscles in the face and support the shape of the face.
