1. Root canal therapy is usually recommended, because tooth decay will spread to the tooth nerve and make the body feel toothache. Remove the necrotic tissue in the pulp, remove the tooth nerve, sterilize it in the pulp cavity, and then repair it with the corresponding filling material to relieve the symptoms of toothache.
2. If the teeth are deeply decayed, conventional conservative treatment is not effective in retaining teeth, so it is recommended to extract teeth directly. At the same time, it is supplemented with analgesic drugs to alleviate the pain of patients as much as possible. After treatment, it is recommended to avoid eating spicy food and go to the hospital for regular review. Dental caries will spread to the pulp cavity over time, causing pulpitis. If the pain caused by dental caries does not spread to the pulp cavity, it is usually a temporary irritating pain. In this case, the caries can be removed and the teeth can be filled. However, if the caries have spread to the pulp cavity, it will cause persistent severe pain and need perfect root canal treatment.
