Of course we need teeth for chewing, but here are the other reasons we need our teeth:
- Making facial expressions
- Starting the digestion process
Parts of a Tooth and Their Functions
Teeth are made up of many different sections and tissues. We will list them for you here.
- This is the top part of the tooth. The shape of the crown enables different functions.
- The anchor that keeps a tooth in place.
- Nerves and blood vessels
- Nerves in the teeth are sensory, they carry information on hot or cold.
- Keep your teeth in place and provide a barrier against infection.
- The enamel is the outer layer of the tooth. It is the hardest and most mineralized tissue for humans. It protects your teeth from damage.
- This is the layer underneath the tooth enamel surface. It absorbs pressure from eating and transfers impulses from the enamel to the pulp.
- Soft, living tissue that consists of nerve tissue and blood vessels.
You only get one set of adult teeth, so it is extremely important that you take care of them!
- Brush your teeth at least twice a day
- Floss at least once a day
- Drink fluoridated water
- Visit your dentist twice a year
