Teeth by Kendal and Sihana
Contrary to popular belief, teeth are very complicated.
Teeth are covered in enamel. Enamel is to protect the teeth and helps you to chew.Under the enamel of the tooth is the dentin. Dentin makes up the largest part of the tooth and is similar to bone. Dentin makes up the most inner part of the tooth called the pulp. The pulp is where each tooth’s nerve is found. The pulp also contains the tooth’s blood vessels, which feeds the tooth; too keep it alive and healthy. Both the dentin and the pulp go all the way down to the root of the tooth, the entire area that’s under your gum. Far below the gums the dentin is covered by the Cementum, which is like your bodies own very strong glue. The Cementum holds the root of each tooth into your jawbone.
The teeth in the centre of the front of your mouth that you can
see the easiest are called the incisors. You have 4 on the top and 4 on
the bottom. Incisors
are shaped like tiny chisels with flat ends and they are sharp. These teeth
help you chomp down on food.
The pointy teeth beside your incisors are called canine teeth. There are 4
canine teeth in total, 2 on the top and 2 on the bottom. These teeth help tear
Beside your canine teeth are your premolars. You have 8 premolars in total, 4 on the top and 4 on the bottom. The premolars are very different than incisors and canines. They are bigger, stronger and have ridges, so that you can crush and grind food.
If you open real wide you will see your Molars. You have 8 in total, 4 on the top and 4 on the bottom. Molars are the toughest of your teeth, they are even wider and stronger then premolars and they have more ridges. Molars work closely with your tongue to help you swallow food.
When kids get older they often get
four more molars all the way in the back of the mouth, 1 in each corner. This
happens around the age 20, and they
are called wisdom teeth. Wisdom teeth aren’t used for anything. Contrary
to popular belief, they don't make you smarter!
