If there is a localized low-density image at the tip of the tooth, this condition is caused by apical inflammation of the tooth and requires root canal treatment of the tooth to remove the nerve and seal the medicine from the root canal. If the fistula does not recover for a long time, surgery can be done to remove the fistula. If there is local swelling and fluctuation, surgical incision and drainage can be performed, together with oral anti-inflammatory drugs and mouthwash, such as cephalosporin or erythromycin, etc. The mouthwash can be compounded with chlorhexidine rinse. Gum abscesses can also be due to cysts, which require surgical removal and treatment of the corresponding teeth. Gum pockets can also be caused by an infection in the space between the teeth or by an eruptive cyst, which requires anti-inflammatory treatment and can be incised to aid eruption.
