Garlic cannot cure toothache, which is usually caused by deep caries, pulpitis, apical periodontitis, etc. The treatments include filling treatment, root canal treatment, incision and drainage of pus, etc., as follows. 1. Filling treatment: If the toothache is caused by deep caries, after removing the decayed material, filling treatment can isolate the irritation and terminate the toothache. 2. Root canal treatment: For toothache caused by pulpitis, inactivate the pulp after opening it under local anesthesia, and then cure the toothache after root canal preparation and root canal filling. 3. Incision and drainage: due to apical periodontitis caused by toothache, only under local anesthesia incision and drainage of pus can effectively relieve pain, usually at the same time with the opening of the pulp cavity. If the toothache is severe or accompanied by other symptoms, it is recommended to go to the hospital in time, under the guidance of the doctor for standardized treatment.
