Brushing your teeth is easy, as long as you brush them clean, but it’s not easy to really brush them clean. Even a smart master will inevitably leave some dead spots, not to mention that the water in the north is originally hard and high in minerals, and nine times out of ten, some tartar and other things will accumulate on the body of the teeth. As a result, bleeding when brushing teeth, bleeding when eating apples, and other troublesome things ensued. By the way, calculus is the main culprit of gingivitis and periodontitis, so I will have the opportunity to talk about it later. Let’s just talk about how to get rid of that annoying dirt. The plaque on the teeth can be removed within 24 hours if you brush your teeth, but if you don’t brush your teeth properly, or if you don’t brush the place, the plaque left behind will gradually calcify into hard tartar, which can’t be removed by brushing, but only by scraping it with hard instruments. In the past, doctors used various sharp scraping instruments for manual scaling, not only the knuckles were sore and stiff, but also the patient was uncomfortable. Later, the ultrasonic scaler was invented, with a water jet, the probe was placed on the tartar, and the whole piece of tartar was shaken off in a while. Because there is water, so it is called “scaling”. In fact, the purpose of the water spray is not to clean the teeth, but to cool the high temperature generated by the high-frequency vibration of the ultrasonic waves, so as not to cause irritation to the teeth. Of course, if the ultrasonic probe has been placed on the surface of the teeth, it will still produce heat, especially for those who have a lot of tartar, very hard, scaling is still a little sore feeling. The purpose of “scaling” is to remove tartar, pigment and other attachments from the teeth, which can prevent the occurrence and development of gingivitis and periodontitis. It can also change the unattractive phenomenon caused by tooth pigmentation, which is also considered an image project. Everyone knows that when you talk to people with a mouth full of black and yellow teeth, your image will be greatly reduced. When you laugh, if you have white teeth, what kind of mental state is that? Therefore, “dental cleaning” is a combination of disease prevention, treatment, and beauty. The teeth must be cleaned one by one, including each side of each tooth, you say, when the teeth are clean, the teeth on the crippled, decay will not be clear? In other words, if you meet a responsible scaling technician, it is equal to a free dental checkup, how good it is. Some people say that scaling can be unpleasant; others say that teeth can become allergic and loose after scaling; some even say that scaling can transmit diseases such as hepatitis and AIDS. All of them are reasonable, but they can be avoided. The uncomfortable scaling is mainly because the tartar buildup is too long and hard, and it takes a long time of vibration to clear the tartar when scaling, so it is inevitable that there will be soreness and pain, which is often endured with a little washing and a light hand from the doctor. Just like the scale in the kettle, if you scrub it once a day, you can gently wipe it off with a towel, but if you don’t remove the scale for several years, then I’m afraid you have to use a knife and a spatula. After scaling your teeth, there may be some sensitivity to hot and cold for a short period of time, which is because the roots of the teeth originally exposed in the mouth are covered by tartar, blocking the hot and cold stimuli without manifesting. But tartar is a bad thing after all, and the exposed tooth roots are also the sins it does, so it is better to have a period of sensitivity than to have the tooth loose and fall off in the end. By the same token, the feeling of loose teeth after scaling is not the fault of scaling, but the teeth were already badly based. As for the problem of infectious diseases, as long as the teeth are cleaned in a regular hospital, the sterilization of instruments is not a problem. After all, what is the purpose of “scaling” should probably be slightly clear. “Tooth cleaning” is to prevent periodontal disease; “scaling” is to eliminate oral odor; “scaling” is for cosmetic purposes; once a year “scaling The purpose of “scaling” is to remove the calculus before it hardens, so as to reduce the pain of scaling; “scaling” at the same time can check the teeth, so that dental diseases can be detected at an early stage, so that “early detection, early treatment”. So it seems that spending a few hundred dollars a year on dental prevention, not only can reduce the trouble of fillings, extractions, but also can save a lot of money on dental implants that. You should know that the cost of veneers is very expensive now, and the teeth are still false.
