Tooth pockets refer to pus pockets that are partially elevated in the gums and may be caused by the presence of calculus irritation around the gums. Gum redness can be excised and drained when inflammation and pockets appear, and after most of the swelling subsides, scaling and subgingival scraping can be chosen to get rid of it. And patients should maintain oral hygiene, always pay attention to plaque control, brush their teeth carefully every day and use dental floss to clean their teeth. Regular review is carried out, once in about 0.5-1 year. Tooth pockets may also refer to apical fistulas, which are caused by inflammation of the root tip. Patients may choose to have a dental root canal and be treated with anti-inflammatory medication. An encrustation may also refer to a bulging gum on an erupting tooth and may be left untreated in patients with no symptoms. In the case of an erupting abscess, an incision and drainage can be chosen to facilitate the eruption of the tooth.
