Drinking motherwort granules toothache may not have anything to do with motherwort itself, it is the disease of the teeth that causes the pain. Motherwort granules are a proprietary Chinese medicine that is commonly used to regulate heavy menstrual periods and to promote uterine contractions after childbirth, and generally have no side effects against teeth. Common causes of toothache are dental caries, pulpitis or apical inflammation. In the early stages of dental disease, the pain is not obvious, may be only occasional pain or hot, cold, sour or sweet stimulation pain. In the later stages, there will be spontaneous pain or pain at night. And motherwort is not directly related to the need for timely filling treatment or root canal treatment to relieve toothache. So drinking motherwort does not directly cause tooth pain, most of them are related to the caries condition of the tooth itself, and need to go to the dentist for examination.
