Toothache can be resolved in different ways depending on the cause, for example, wedge-shaped chipped teeth, caries, pulpitis, etc. can lead to toothache, part of which requires medication, part of which requires oral treatment such as filling and root canal therapy. 1. Wedge-shaped defects: If the defect is small, the tooth can be filled directly after removing the decayed necrotic material inside the defect; if the defect is large, root canal treatment is needed before filling. 2. Dental caries: commonly known as insect teeth, mostly caused by bacterial infection, the treatment is mainly medication and filling, based on grinding away the caries, applying sodium fluoride to inhibit the development of caries, and then filling with suitable filling materials, such as silver amalgam, compound resin, etc., so as to restore its form and function. 3. Pulpitis: The treatment mainly adopts root canal therapy, which aims at preserving the living pulp for reproducible pulpitis; for non-reproducible pulpitis, the pulp needs to be removed to preserve the affected tooth. If you have toothache, it is recommended that you visit a hospital to find out the cause of the toothache and then treat it.
