Periodontitis is an inflammatory and destructive disease of tooth supporting tissues, which is mainly caused by bacterial infection, and there are also many systemic and local promoting factors, mainly dental calculus and dental plaque causing inflammatory damage. Treatment is divided into the following aspects:

1, acute or emergency treatment, such as periodontal abscess, requires urgent anti-inflammatory, analgesic and abscess drainage;

2. Basic periodontal treatment, including oral hygiene education, scaling, scaling and root planing. It usually takes 2-3 times, and each treatment takes about 1 hour. After the treatment, the patient should be evaluated. After 6-8 weeks of basic treatment, the patient will be advised to make a follow-up visit, and the oral hygiene status of the patient will be evaluated after the follow-up visit, and some risk factors will be evaluated.

3, surgical treatment, some teeth have bleeding, periodontal pocket probing depth is greater than 5mm, root bifurcation lesions 2-3 degrees. In the case of bad alveolar bone and gum morphology, surgery will be performed, and it is recommended to carry out orthodontic and prosthetic treatment after three months of surgery.

4, periodontal support treatment, support treatment is to persuade patients to go home for oral maintenance, oral maintenance is also very important, if bacteria and dental calculus are well maintained, it will grow slowly, and the inflammatory damage to periodontal bones will be less. Periodontitis will not have any symptoms, and patients will come to see a doctor because of loose teeth and bleeding gums. Once the patient finds that the teeth are loose, it will be difficult to treat. It is suggested that patients should have regular oral examination to find periodontitis early and treat it early to prevent further damage.
