Teeth

Teeth are used to break down food.

The first set (sometimes called baby teeth) feature 20 teeth. The second set (sometimes called adult teeth) features 32 teeth. Baby teeth are usually replaced by adult teeth between the ages of 6 and 12. Humans have a variety of teeth including molars, premolars, canines and incisors. Incisors help to bite pieces from food. Canines help to hold and tear food apart. Molars help grind food. Teeth are covered in a hard substance called enamel.

Teeth are surrounded by gums.

Cavities can damage a tooth if left untreated.

Braces are often used to help straighten align teeth.

Teeth are like bones. They are alive and they start forming before you are born and continue to develop until you are an adult.

Teeth form inside the jaw and are nourished and protected by the pink tissue that surrounds them. The crown is the part of the tooth you can see above the gums, but there is a lot more to your teeth than that.
