|In order to understand the descriptions of dental treatments, it can be useful to know more about the anatomy of a tooth. Here you can see a cross section of a tooth showing the different components within the tooth.|
Only the visible part of a tooth is covered by enamel. The tooth mainly consists of dentin, which consists of calciumhydroxylapatit like the enamel. The mineral only makes up a third of the dentin, which makes this material softer than enamel. Contrary to enamel, dentin is sensitive as it contains a number of channels leading to the nerve system of the tooth.
In the heart of the tooth is the dental pulp, which is the nerve of the tooth. The pulp is the only soft tissue in the tooth. It consists of arteries, veins, nerve systems and lymphatic tissue. The pulp is the substance, which makes sure you can feel pain in the tooth when the enamel is broken down by caries.
The root is the part of the tooth, which is hidden under the gum. The root makes up two thirds of the tooth, and serves to fasten the tooth into the jawbone.
