There are four different substances which make up our teeth, and each substance has its own job to do. The hard and shiny white substance which covers every tooth is called enamel, and this protects the tooth from the bacteria which can cause decay. Lower down the tooth is a substance like bone which protects the root of the tooth. This is called cementum. Beneath the enamel is a material called dentine, which is a little like ivory, and which makes up the main body of the tooth. At the tooth's centre is a space filled with dental pulp. This pulp contains the blood vessels and nerves that keeps the tooth alive and can cause it to hurt if bacteria manage to get through the two other substances. This can be prevented if you take good care of your teeth, and there is every reason to do just that, isn't there? Who wants rotten and painful teeth?

Caritin. I think that's how you spell it. The same stuff your finger nails are made of!
