K02.2: Caries of cementum

Pathogens have damaged your tooth.

If a tooth has been damaged by pathogens, this is called caries. If you have plaque or eat sugar frequently, the tooth can be damaged by pathogens more quickly. Furthermore, some people’s teeth are generally more susceptible to caries.

In your case, the tooth material on the tooth root was damaged. That can happen for instance when the gums have retracted, making the tooth root visible.

Every tooth consists of three sections: the crown, the tooth neck (cervix) and the tooth root. The crown is the visible part of the tooth. The tooth neck is covered by the gums. The tooth root keeps the tooth in the jawbone.

If the tooth root has been damaged, it may then appear discolored. If the tooth material has been damaged, the interior of the tooth may then become inflamed. There may then be a toothache, for example. Every tooth has a hollow interior. Connective tissue such as nerves and blood vessels is found inside a tooth. Through its interior, a tooth is formed and sustained.
