First, I brush my teeth very carefully, I don’t need to clean them. Some people think that if you brush your teeth seriously every day, you don’t need to scaling, which is not true. Because plaque is generated very fast, new plaque will be formed within half an hour after thorough cleaning and brushing, and it can reach the maximum amount within 30 days. What’s more, most people do not master the correct method of brushing, but only according to their own habits of dental cleaning, inevitably some parts of the brush is not in place, especially in the gap between the teeth and the lower front teeth inside, and over time that becomes calculus, therefore, adults who have not scaled, go to the hospital as soon as possible to do a cleaning, and it is best to do once every six months. Second, teeth will become white after cleaning First of all, we have to correct a misconception: some people think that healthy teeth are pure white, just like the teeth of the models in toothpaste commercials. In fact, this is wrong. The structure of a normal tooth is a layer of more transparent enamel containing yellowish dentin, so it can transmit some of the color of the dentin, so the color of a normal tooth should be slightly yellow. Teeth that are particularly white and not transparent usually give an unrealistic appearance. Some pigmentation is sure to accumulate on the surface of the teeth during daily use, and this pigmentation can make the color of the teeth look more unattractive. An important goal of scaling is to remove this pigment to the greatest extent possible, so after a perfect scaling, the teeth will reveal their own color, a light yellow, as this stained pigment is well removed. Overall, teeth will whiten to some extent after a scaling, however, as a means of preventing and treating periodontal disease, the effect of scaling to whiten teeth is extremely limited. Patients can improve the appearance of their teeth more significantly through other means such as cold light whitening, aesthetic restoration and other techniques. Third, how often to clean teeth In developed countries, dental cleaning has become a very popular routine oral health care, people regularly go to their dentist once or twice a year to clean their teeth. After scaling, if periodontal disease is found, the dentist will promptly carry out oral professional treatment to maintain oral health. Moreover, the dentist will make a follow-up plan for each patient with different conditions, including the health status of periodontal tissues, oral hygiene, oral cleaning habits, lifestyle habits, etc. Some patients with poor periodontal, may need to come to the hospital two or three months to review, while some patients with better oral hygiene, may be two or three years once a dental cleaning can. In short, it is more appropriate for people to have their teeth scaled once every six months to a year. Fourth, dental scaling on teeth damage Correct dental scaling is no damage to teeth. The normal tooth surface is a layer of tooth enamel, very high hardness, can completely ignore the impact caused by scaling. The rubber wheel used for polishing is a soft material, and will not cause wear and tear on the teeth. Five, scaling will lead to larger gaps This fear makes many people refuse to clean their teeth. In fact, the accumulation of tartar, gum inflammation will lead to local swelling of the gums to fill the gap, and after scaling to remove the tartar, gum swelling gradually recede, so the gap becomes obvious, tongue licking up the outline of the teeth is also more obvious, feel that the teeth have become longer, this is the current restoration of the true face of the teeth, not caused by scaling. This is just like the process of quitting smoking, which will certainly cause various uncomfortable reactions, but the benefits of quitting smoking are self-evident. Similarly, if you refuse to clean your teeth for fear that the gap will look bigger and prefer to maintain the inflammation and swelling of the gums, it is extremely unwise and may lead to more serious consequences. Sixth, scaling can lead to tooth sensitivity Tartar is like a thick cotton coat that wraps around the outer layer of the teeth. After the removal of tartar by scaling, the teeth are exposed to the long-lost external environment, which will produce all kinds of strange feelings. In the case of healthy teeth, this sensitivity will usually disappear within one to two weeks after the scaling. When scaling, you can effectively avoid the soreness by doing the following: 1. Scaling in parts: For patients with more and thicker calculus, poor anti-inflammatory effect of drugs or poor desensitization treatment, experts suggest that scaling in parts, doing it once is too hard for these patients, and scaling in parts, “turning the whole thing into zero”, patients can easily accept In addition, in between scaling, can also continue anti-inflammatory treatment or desensitization treatment, which can greatly reduce the soreness, but also improve the anti-inflammatory or desensitization treatment effect, can also reduce the scaling and scaling after the “bloody taste” in the mouth. 2, regular scaling: the accumulated calculus over the years and hard, so that the scaling machine needs to increase the strength to remove, which will aggravate the tooth soreness. Therefore, experts believe that, according to the formation of calculus and gum inflammation, six months, one year or two years of regular scaling, when the calculus is small, the amount of formation is not much, the quality is loose, it is easy to remove, so regular scaling, it is not easy to cause soreness when scaling. 3, desensitization treatment before scaling: the “soreness and softness” caused by scaling is mainly due to tooth sensitivity. According to clinical observation, the majority of people who have severe soreness in scaling are sensitive to hot, cold, sour and sweet stimuli in daily life. It is recommended to use toothpaste with desensitizing effect to desensitize the teeth 4-10 days before scaling, which can reduce the soreness and softness during scaling. You can continue to use it even after the scaling to reduce the soreness and tenderness after the scaling.
