There is a specialized term for dental cleaning called scaling, which is done to combat periodontal disease, not just for aesthetic purposes. The incidence of periodontal disease is very high, 80% of the population suffers from varying degrees of periodontal disease, but most people just do not care. And scaling is the first step in effectively treating periodontal disease. When bacteria and food debris left on the surface of the teeth are not removed, hard deposits will form on the surface of the teeth, which is called tartar. Once tartar is formed, it tends to accumulate more disease-causing bacteria, which in turn triggers and aggravates periodontal disease. Even with careful and proper brushing, only 70% of the bacteria in the mouth can be removed, and the remaining 30% will remain in the spaces between the teeth and in the gingival sulcus. For this reason, regular scaling is very important, through the scaling can completely remove the bacteria in the tooth surface and tooth gap, effective prevention and treatment of periodontal disease. Dental experts recommend that the public should go to the hospital every six months for a periodontal specialist examination and scaling. In the “scaling can whiten teeth” problem, dental experts explain: “scaling is not for dental beauty, but to remove bacteria on the surface of the teeth, tartar, and some pigmentation (such as: tea stains, tobacco stains, coffee stains, etc.). But scaling is just to clean the teeth, if the teeth themselves exist tetracycline, fluorosis and enamel underdevelopment, etc., scaling is not going to change the color of the teeth.” In recent years, people’s awareness of oral health care has increased, more people scaling, but there are still a lot of people are afraid of scaling, there are the following misconceptions: First of all, some people think that “scaling bleeding gums is very scary”. In fact, this is a very common normal reaction, is the result of inflammation of the gums, rather than scaling stabbed gums, normal people after the end of scaling gum bleeding will stop by itself; Second, some people think that “scaling the gap between the teeth increase. In fact, this is due to the original gap was occupied by a large number of tartar, did not feel the existence of the gap. After scaling removes the tartar at once, the gap is exposed and the gap is felt to be enlarged. This is the result of periodontal disease, not due to scaling; again, there are many people think that “scaling will grind off the tooth surface enamel. Scaling removes tartar and stains on the surface of the teeth, does not wear the enamel, there is no harm to the teeth; Finally, some people think that “scaling will cause hot and cold allergies to the teeth, it is better not to wash”, which is obviously not true. Packed in the teeth after the surface of the tartar is removed, the root of the teeth exposed, hot and cold sweet and sour stimulation will appear when the teeth allergy, which is a normal reaction after scaling. This is a normal reaction after scaling. After a period of time using desensitizing toothpaste, this allergic symptom will gradually be relieved. If you refuse to have your teeth cleaned because of fear and misunderstanding of scaling, periodontal inflammation cannot be effectively and timely controlled, and your teeth will be difficult to protect. –Clean your teeth every six months, have you done it?
