Percussion and gum massage are traditional periodontal tissue health care methods, which are widely circulated among the people. The above two methods have a common feature, that is, they can promote blood circulation of tissues around teeth. Because tapping promotes the blood circulation of periodontal ligament system, when the blood circulation of periodontal ligament system is vigorous, it can strengthen the firm function of teeth and increase the stability of teeth, that is to say, tapping health care can make teeth firm and prevent or reduce tooth loosening. As far as health care is concerned, the most noteworthy thing is that, in general, there are many people who knock their teeth with high intensity, but few people knock their teeth with appropriate intensity. If you feel vibration but no pain at the tip of your teeth when you tap them, you can say that this tapping intensity is the most beneficial to your teeth. People who hold different opinions want to ask, is it that the greater the intensity of knocking teeth, the better the blood circulation? The answer is no, because the greater the intensity of knocking, the greater the damage to periodontal ligament during periodontitis, so it is reminded that the intensity of knocking is lighter than excessive force. Because it takes a long time to produce results, at least stick to 1? It takes two years to show the effect. Percussion can be divided into full-mouth method and local method. When the situation of periodontitis in oral cavity is the same, it means that alveolar bone absorption and tooth loosening are the same, and the whole mouth method can be used to knock teeth. If the tooth looseness is different, you can knock the teeth with one side tooth or front tooth in groups. Every time you knock your teeth or massage, if you press 10 minutes, then health care twice a day is enough. If the time is not a unit, then every time you knock your teeth, it is 100 times, which is also twice a day. If the gum massage method takes a circle as one time, the whole oral gum needs at least 100 times. If you have a toothache, don't knock your teeth, so as not to aggravate the pain or cause the lesion to worsen. In promoting the blood circulation of periodontal tissue, the effect of gum massage is obviously not as good as that of knocking teeth, because gum massage can only massage buccal and labial gums, while lingual gums of teeth can only touch gums with the tip of the tongue instead of massage. Although there are some shortcomings in gum massage, it can not only promote blood circulation, but also promote secretion excretion in periodontal pocket, accelerate periodontal tissue metabolism and help periodontal tissue inflammation subside. Therefore, it can be said that gingival massage is indispensable in periodontal tissue health care methods, especially when the periodontal pocket is not well drained, inflammatory secretions can be discharged through gingival massage. What needs to be distinguished here is that the method of gum massage is not periodontal pocket extrusion. If there is pus in the periodontal pocket, the gum in the pocket wall is obviously swollen, which can never be solved by gum massage. It must be solved by treatment, otherwise it will cause inflammation and infection and aggravate the occurrence and development of periodontitis. Swelling of periodontal pocket is an absolute contraindication for gum massage.
