Pain around the teeth may be caused by gingival tumor, periodontal abscess, periapical abscess and so on. 1. Gingivoma: Usually, gingivoma will destroy the growth of teeth, leading to loosening and shifting of teeth, which will lead to redness and inflammation of gums, and there may be swelling and pain around teeth. 2. Periodontal abscess: If the patient does not pay attention to oral hygiene, the tartar and plaque around the gums will irritate the gums, which will lead to bleeding, swelling and pus in the gums, and there may be swelling and pain around the teeth. 3. Periapical abscess: If a patient’s caries problem is not treated in time, when it develops into periapical lesions, a periapical abscess may form if the pus cannot be drained. When the gums bulge with pus, there may be swelling and pain around the tooth. There may be many other causes of pain around the tooth, and patients are advised to actively seek medical attention to identify the cause and then standardize treatment.
