If the periodontal pocket reaches the root tip and the tooth loosening is very obvious, it is necessary to consider tooth extraction. For some patients whose tooth loosening is not obvious, temporary or permanent periodontal splints can be made to fix the loose teeth according to the actual situation, treatment of periodontal abscess, abscess can be incised and drained when the abscess has been confined, and the periodontal pocket should be rinsed and drugged at the same time.
