K02.1: Caries of dentine

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 topmost layer of the tooth and the tooth material beneath it was damaged.

If the tooth material is damaged, the region can then appear yellow or brown. In that case, a hole in the tooth can sometimes be seen. 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.
