Periodontitis is a chronic disease that is often overlooked by the majority of patients because it is usually not noticeable during its slow development. About 80% of patients come to the hospital only when their periodontal disease has progressed to a moderate or even severe stage. In the early stages of periodontitis, there are no obvious symptoms and no pain, unlike inflammation of the nerves of the teeth, which causes severe pain due to the pulp chamber closing and pressing on the nerves. Inflammation of the tissues around the teeth (gums and alveolar bone, etc.), often manifested as bleeding gums, soft tissue swelling and chronic resorption of bone tissue, there is no obvious symptoms of nerve compression, so there is no severe pain, often do not get people’s attention. And then lead to the condition is getting worse and worse, until the beginning of the impact of chewing function and aesthetics to the periodontist, often this time has lost the good opportunity to treat, can only be hopeless treatment of the affected teeth extraction. And this is a considerable part of the patients early gingivitis, periodontitis is the gingivitis further aggravation of the cause. When the disease develops into periodontitis, chronic inflammation has invaded to the deep periodontal tissues, in addition to the symptoms of bleeding and swelling of the gums appeared in gingivitis, but also accompanied by the formation of periodontal pockets, alveolar bone resorption, and the teeth gradually loose, chewing powerlessness and so on. The treatment for periodontitis is only to control the development and deterioration of the condition, and regeneration of periodontal tissues is difficult to achieve, so the loss of periodontal tissues is often irreversible. However, if the inflammation is simply limited to the gums, after thorough and perfect treatment, the periodontal tissues can be restored to a healthy state and the disease is reversible. In addition, early periodontitis, if effectively controlled, can achieve good therapeutic results. Therefore, the prevention and early treatment of periodontal disease is very important. A word to the wise: bleeding gums should not be ignored. Bleeding gums is the early manifestation of periodontal inflammation, most patients do not pay attention to, delayed treatment, hold a get-by mentality, resulting in aggravation of the condition, missed the best time for treatment. In addition, it is worth emphasizing that periodontitis will also affect the health of the whole body, such as: diabetes, cardiovascular and cerebrovascular disease, renal disease, gastric disease, lung infection, premature birth, etc., the development and regression of these systemic diseases and periodontal disease have a close relationship with each other. Warm tips: this at least every six months for oral examination and dental cleaning, if deep infection should also receive thorough periodontal treatment to control the further development of periodontal inflammation. Just because your teeth have no obvious symptoms does not mean they are healthy. You should enhance your awareness of preventing periodontal disease, maintaining oral health, and developing good oral health habits to improve our quality of life.
