K02.9: Dental caries, unspecified

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.

The tooth may be discolored by the damage. You may also have a hole in your tooth or have a toothache, for example.
