Periodontal disease is a common oral disease and one of the main causes of tooth loss in adults, as well as a major oral disease that endangers human teeth and general health. Old people used to say “old people lose their teeth, old people lose their teeth”, thinking that losing teeth in old age is a helpless destiny. In fact, the vast majority of elderly people in China missing teeth are caused by periodontal disease. The actual fact is that there is no inevitable connection between tooth loss and getting older, as long as it is properly maintained, you can still eat peanuts when you are 100 years old ~ periodontal disease is a chronic disease that occurs in the tissue around the teeth, divided into two categories: gum disease and periodontitis. Here, I first explain to you the periodontal tissue is a god? The tooth we normally see is not the whole tooth, but only the crown of the tooth (like the crown of a tree), and the other two-thirds of the tooth is the root, which is buried inside the bone so that the tooth can withstand the biting force when eating. We can compare the tooth to a tree, and the periodontal tissue is the soil on which the tree is rooted. Once the “soil” goes wrong, the “tree” will lose its support, so the tooth will gradually loosen and eventually fall off. Eight questions to help you evaluate your periodontal health ◆ ① Do your gums bleed when you brush your teeth or eat hard food? ② Do your gums often swell and hurt? ③ Is the gap between your teeth gradually increasing? ④ Are your gums receding? ⑤ Are your teeth loose? (6) Do your teeth look longer than before? ⑦ Do you have persistent bad breath (halitosis)? ⑧ Do your teeth have no strength when chewing or are painful when chewing? If you have any of the above symptoms, you should take action to protect your periodontal health. Why do you get periodontal disease? Except for a very small number of people who have periodontal disease due to endocrine and blood diseases, the majority of our periodontal disease patients can be said to be caused by long-term oral hygiene self-cleaning, and not regular scaling and regular checkups. The early symptoms of periodontal disease are not obvious, and there is no pain, so it is often ignored, resulting in long-term chronic infection of periodontal tissue and recurrent inflammation. Often wait until the alveolar bone resorption to a certain extent, patients have obvious weakness in biting, hot and cold sensitivity and even loose teeth, only to be alerted, by this time the chewing function of teeth has been greatly reduced, and even affect the health of the whole body. Prevention & treatment of periodontal disease Prevention: effective brushing, thorough removal of plaque; regular checkups by professional doctors, usually once a year, early diagnosis, early treatment, to avoid the development of periodontal disease. Treatment: Basic treatment, supragingival scaling, subgingival scraping, root surface leveling and loosening of dental wires and resin splint fixation.
