What should I do if my tooth hurts one year after a filling?

If tooth pain occurs one year after a dental filling, it may be due to incomplete removal of bacteria inside the tooth during the initial procedure, leading to reinfection. In addition, using inappropriate filling materials or incorrect filling techniques may also cause tooth pain. If this occurs, prompt medical attention is recommended. An oral health professional will perform a comprehensive examination to determine the cause of the pain. If the pain is caused by bacterial infection, the dentist will perform thorough cleaning and disinfection treatment to eliminate bacteria inside the tooth and prevent the spread of infection. If the filling material is unsuitable, the dentist will replace it with an appropriate one to avoid further damage to the tooth. The dentist will also select the most suitable treatment based on the specific condition. In cases of severe tooth damage, root canal treatment or tooth extraction may be necessary. For minor issues, localized treatments such as topical medications or surface repair of the tooth may help relieve pain. In addition to seeking professional dental care, patients can take certain measures in daily life to alleviate tooth pain. For example, rinsing the mouth with warm salt water can help reduce pain and kill bacteria. Maintaining good oral hygiene by brushing regularly and using dental floss can effectively prevent tooth infections.
