Some of these reasons may be:
- A crowded mouth – Teeth may need to be extracted in order to prepare the mouth for braces or to make room for teeth that are trying to break through the gums.
- Infection – A tooth may need to be extracted if tooth decay has reached to the pulp, which is the center of the tooth that contains the nerves and blood vessels. Extraction will help prevent the further spread of tooth decay.
- Risk of infection – Finally, a tooth may need to be extracted if you have a low immune system from chemotherapy or an organ transplant. The risk of infection may be worth extracting the tooth in order to prevent it from spreading.
