How to treat periodontitis? What causes periodontitis?

Periodontitis is a chronic infectious disease of periodontal supporting tissue, which will lead to the destruction of supporting tissue, such as periodontal pocket formation, attachment loss, alveolar bone absorption, etc., and finally lead to tooth loosening and tooth loss. The etiology of periodontitis can be divided into "local promoting factors" and "systemic promoting factors". Local promoting factors refer to local factors that affect periodontal health, such as mouth, teeth and occlusion. Dental plaque biofilm is the initial factor of inflammation and destruction of periodontal tissue. Some local factors, such as dental calculus, crowded teeth arrangement, abnormal anatomical morphology, poor restoration, hanging teeth filling, occlusal trauma, food impaction, etc. Will promote the retention and accumulation of dental plaque, hinder the removal of dental plaque, and bacteria will begin to grow and reproduce under the gums. When the balance between the defense mechanism and the microorganism of the sick individual is broken, periodontal damage will occur.

Although the existence of dental plaque is a necessary condition for periodontitis, microorganisms alone are not enough to cause the disease. A large number of studies have shown that the response of sick individuals to microorganisms plays a very important role in the occurrence and development of periodontitis. Systemic promoting factors, such as genetic factors, endocrine, smoking, diabetes, osteoporosis, mental stress, etc. It may affect and change the individual's response to microorganisms, reduce the resistance and repair ability of periodontal tissue, and determine the progress speed and severity of the disease. It should be emphasized that smoking is a high risk factor for periodontal disease, especially severe periodontitis. Compared with non-smokers, the prevalence of periodontitis in smokers is higher and more serious.
