The process of wisdom tooth abscess cleaning includes rinsing, medication, and post-cleaning treatment as follows. 1. Rinsing: Use saline, 1%~3% hydrogen peroxide solution or 0.1% chlorhexidine solution to rinse the gingival pocket repeatedly until the overflow liquid becomes clear. 2. Medication: Place iodized glycerin or povidone-iodine into the gingival pocket 1~3 times a day. 3. Post-cleaning treatment: After the inflammation subsides, if the wisdom tooth can be retained, perform pericoronal gingival flap excision to eliminate the blind pocket. If the wisdom tooth has no value for retention, it should be extracted as soon as possible to prevent the recurrence of pericoronitis. If a buccal fistula arises, the fistula tract should be removed. If the wisdom tooth is abscessed, or accompanied by other symptoms, it is recommended to go to the hospital in time to receive professional treatment.
