Some people think that scaling can cause damage to the teeth, but in fact this perception is wrong. For this reason, dental experts recommend that people should clean their teeth regularly. In recent years, with the increasing awareness of the importance of dental care, the term “dental cleaning” has gradually come into the lives of ordinary people. However, there are still some people who do not know much about dental cleaning, there are misconceptions. One of the misconceptions: scaling will lead to an increase in the gap between the teeth and damage to the teeth. People who hold this view are, first of all, ignorant of the principle and purpose of scaling. At present, the scaling performed in hospitals and regular dental clinics is to remove the calculus and calcified dirt on the surface of teeth through high-frequency oscillation of ultrasonic waves to avoid their further stimulation of gums and symptoms such as bleeding, fear of acid, fear of sweet, fear of heat and fear of cold, which in turn lead to inflammation of gums. This cleaning is not wear and tear on the teeth. As for the gap problem, this is already there, but long time without cleaning the gap, let the calculus to clog up. Myth No. 2: Scaling is costly, time-consuming and uncomfortable, and is unnecessary. Generally speaking, it is enough to clean your teeth once every six months or once a year. For smokers, it is best to have a cleaning once every 3 months or so. Regular dental cleaning, not only clean the teeth, the doctor can also do a dental examination for the scaling, so as to facilitate the timely detection of problems, timely treatment. The first time you have your teeth cleaned, it may be a little hard because of more tartar, but as long as you stick to it and pay attention to keeping your mouth clean, the next cleaning will be much better. In addition, be sure to go to a regular dental hospital or clinic to have your teeth cleaned. Because scaling generally goes through four procedures: tartar removal, sandblasting, pigment removal, and polishing, and those scaling clinics that charge very low fees generally only do the first step and cannot achieve the purpose of health care.
