Avoid using horizontal brushing method on brushing method. However, the horizontal brushing method is the customary brushing method of the masses, and many people use gravity to make a pull-saw horizontal brushing with a hard-bristled toothbrush, resulting in gum recession, root exposure, cervical wedge defect and other diseases. Therefore, the correct practice is to use a toothbrush with two rows of twelve bristles, using the vertical brushing method, i.e., when brushing the upper teeth, the bristles are brushed from the top down along with the teeth; when brushing the lower teeth, they are brushed from the bottom up along with the teeth. The action should be slower, repeated several times on the same part, so that the bristles through the junction area of the gums and teeth thoroughly remove dirt, the gums also have a massage effect. 2, gum massage method: after brushing teeth with clean hands index finger in the teeth and gum surface for circular rotation massage. You can start from the upper and lower jaw back teeth, and gradually move to the front. Once in the morning and once in the evening, 10 to 15 minutes each time. However, the massage should not be done during acute inflammation. If the tartar accumulation is more, should also ask the dentist to scrape the tartar first, before using gum massage. 3, pay close attention to the early signs of periodontal disease. If the gums bleed when you brush your teeth or eat, you should pay attention to it early, because it is a manifestation of periodontal inflammation and should be treated at the hospital as soon as possible. 4. Develop healthy eating habits. Pay attention to the diet structure to nutritionally balanced, eat more white meat, eggs, vegetables, fruits and other foods beneficial to dental oral health; try to eat less sugary food, do not smoke, less alcohol, eat more fiber-rich chewy food, effectively increase saliva secretion, conducive to dental surface and oral cleaning. 5.Regular oral health examination. If possible, ensure that children once every six months, adults once a year, to the hospital dental specialist oral and dental health examination; every six months or once a year to the hospital dental cleaning, timely removal of subgingival calculus. Periodontitis treatment Periodontitis treatment is divided into four stages: the first stage is the basic treatment stage, the purpose is to choose the conventional treatment of periodontal disease, remove or control the clinical inflammation and bite pathogenic factors, including oral self-cleaning, extraction of poor prognosis and unfavorable restoration of teeth, supragingival scaling, subgingival scraping to remove plaque, tartar, choose antibacterial drugs to control inflammation, bite jaw adjustment, etc. The second stage is periodontal surgery and fixation of loosened teeth. The third stage is the permanent restorative treatment, which is usually performed 2-3 months after the surgery. The fourth phase is the review and retreatment phase, which is performed every six months and includes plaque control checks, hygiene promotion, and radiographic examinations for further development of the treatment plan. The key to the success of periodontitis treatment is two things: 1, thorough treatment plan and meticulous and superb treatment by doctors. 2, adherence to good self plaque control. The latter is more important than the former, otherwise the doctor’s work will be half-hearted, and the disease will occur again. The following are a few simple practices: 1, periodontitis treatment is based on local treatment, the first is to remove the tartar above the gums (medically known as supragingival tartar), and then remove the tartar in the periodontal pockets (i.e. subgingival tartar), and scrape the periodontal pockets containing a large number of bacterial toxins in the diseased bone, after these treatments, gum redness and swelling can subside, gum bleeding and periodontal pockets overflowing pus can disappear. 2, after the formation of periodontal pockets, usually the periodontal pockets for drug treatment, can be placed in the periodontal pockets of various drugs, such as iodine glycerin, compound iodine solution or antibacterial drugs, so that the periodontal pockets to maintain a high concentration of drugs to destroy the periodontal pockets of various bacteria, to achieve the role of sterilization, anti-inflammatory and astringent. After the above-mentioned treatment, those with poor efficacy need periodontal surgery. 3.For those who have loose teeth, different methods can be taken to perform loose teeth fixation. For serious condition and more destruction of periodontal tissues, Si teeth that cannot be retained, they need to be extracted. In addition to local treatment, those with obvious serious symptoms can take systemic treatment, i.e. oral antibacterial drugs, such as metronidazole, 3 times a day, 0.2 g each time for 1 week; spiramycin, 4 times a day, 0.2 g each time for 1 week; tinidazole, 2 times a day, 0.5 g each time. 4, periodontitis early treatment effect is good, can make the lesion stop development, periodontal tissue can be repaired to a certain extent, therefore, when the gums appear red and swollen, need to promptly go to the hospital for examination, diagnosis and treatment.
