Tooth plugging pain may be due to large gaps in the teeth, dental caries, acute gingivopapillitis and other reasons. 1. Large gaps between teeth: patients with large gaps between teeth may set food debris in the gaps between teeth when eating, which may cause physical stimulation for a long time, oppressing the gums and alveolar bone, resulting in pain and other symptoms. 2. Dental caries: If the patient has dental caries and has not been treated for a long time, the food may be embedded in the cavities when eating, resulting in compression of the gums, so there will be symptoms of tooth pain. 3. Acute gingivopapillitis: If the patient suffers from acute gingivopapillitis, the food stuffed into the teeth may produce stimulation of the interstices, resulting in symptoms of tooth pain, it is recommended that the patient should clean the tooth surface in a timely manner, and go to the hospital for the appropriate anti-infective treatment. If the patient is stuffed teeth when eating, should be timely cleaning, and maintain oral hygiene, can help relieve pain.
