1.I often bleed when I brush my teeth, must be because I brush too vigorously? Explanation: Bleeding from brushing is caused by inflammation of the flesh of the teeth (periodontitis), but many people misunderstand that the bleeding is caused by brushing too vigorously to damage the flesh of the teeth. On the contrary, because they avoid the flesh of the teeth and do not brush the flesh of the teeth, a vicious circle is formed and the area around the flesh of the teeth becomes more and more dirty, prompting periodontal disease to worsen. On the contrary, when we brush our teeth to bleed, it is more important to brush the flesh of the teeth that bleed (inflammation). Usually it will heal in a few days, but if the situation is serious, you should see your dentist for a check-up. On the contrary, some people are afraid of not brushing cleanly, so they brush harder. In fact, a long period of vigorous brushing also has adverse effects, it will make the flesh of the teeth shrink and enamel damage, teeth become sensitive, and even to the invasion of bacteria into the dental pulp, so that the teeth necrosis. 2.After scaling, the gap between the teeth increases and the teeth become sore and soft, must be the scaling of my teeth? Some patients feel that their teeth are sore and soft after scaling, and they find that the gap between their teeth has increased and they can easily hide food, so they think that the scaling must have damaged their teeth and made the gap thinner, and they decide not to scaling again. In fact, generally do not have the habit of regular dental cleaning, some may be more than ten years have not been cleaned, but also met a lot of male patients in their thirties and forties before the first dental cleaning, the original because of the wedding photos, forced by the other half to go to the dental cleaning. A large amount of tartar accumulation to inflammation of the flesh of the teeth, when scaling, the teeth are re-exposed, there will be sensitive situation, about three or four days after the degree will slowly reduce. Scaling is the use of ultrasonic shock off the tartar, will not damage the teeth, and the tartar between the teeth clean, coupled with the flesh of the teeth to reduce inflammation, it will be felt that the gap between the teeth increased, do not worry too much. 3, missing a large tooth, I still have a few teeth, and does not affect the appearance, do not need to set teeth? The absence of a large tooth, symmetrical tooth overgrowth, resulting in abnormal tooth surface contact, affecting the chewing ability and normal bite relationship will cause the adjacent teeth to move into the missing tooth position. The increased gap between the teeth will increase the risk of tooth decay and periodontal disease, and other teeth will be easily damaged due to the domino effect. The loss of one tooth will cause the back teeth to lose their support and the incisors will become sentinel teeth, affecting the appearance. Therefore, we have to take care of the teeth and try to retain them, if we have to lose teeth, we have to insert teeth to avoid the situation of tooth displacement. 4.Children’s tooth decay will be replaced later, do not need to pay attention to it? People generally think that children’s teeth will be replaced, so it doesn’t matter if they have decayed, and if it hurts at most, they will have their teeth removed. In fact, children will not complete the tooth replacement process until they are 12 to 13 years old, so if they lose their baby teeth too early, the six-year-old teeth will be misaligned and the baby molars will not grow out in the right place. In addition, tooth decay will lead to inflammation and infection of the developing permanent teeth below, so the situation of tooth decay in children should not be ignored. 5, pregnant women bad teeth, because the baby draws away the calcium in the teeth many people think that during pregnancy, easy to bad teeth and tooth decay, must be because the fetus in the abdomen draw away her calcium? In fact, this is a general misunderstanding, in fact, pregnant women have a greater chance of bad teeth for the following reasons: during pregnancy, due to hormonal changes, pregnant women’s gums are easily stimulated by the toxins secreted by the dental film and redness and bleeding, this phenomenon is called gingivitis during pregnancy; during pregnancy, pregnant women’s dietary habits have changed, but also eat more sweet and sour food than usual, coupled with easy vomiting, so easy to tooth decay. Even if a pregnant woman has a toothache, she is afraid to go to the dentist for fear that it will affect her baby; in fact, general checkups and teeth cleaning are not a problem. However, the first trimester is a dangerous period, so X-rays are not allowed; after the first trimester, doctors will decide as needed, but if not necessary, otherwise they will try to avoid. 6. I do not take X-ray because it is not necessary and there is radiation. According to the British Dental Association guidelines, the general public need to take X-rays once every two years to check their teeth. If you belong to a high-risk group, you should be photographed once every six months. In fact, X-rays can check the hidden locations of the teeth and the foot of the teeth, so that dental problems can be detected early, but patients generally think that doctors can check the teeth with the naked eye, so they do not need to take X-rays. When a doctor finds tooth decay with the naked eye, the condition is usually more serious, and X-rays can help the doctor make an early diagnosis. In addition, the radiation of X-ray used in dentistry is very low and will not have adverse effects on the body. The new digital X-ray radiation is one tenth of the traditional one, so you can rest assured. 7.The filled tooth will not be decayed again in the future. Generally, patients think that the filled tooth is permanent and will not be decayed again in the future. But imagine, a healthy and normal tooth can be decayed, how can a filled tooth not be decayed again? When the filling powder is affected by cold, heat, acidity and chewing strength, it will start to deform and become easily decayed over time. In addition, tooth decay is usually caused by bad eating habits and oral hygiene, if the situation is not improved, the filled tooth will be more prone to decay. The dentist will also analyze the patient’s drinking habits to reduce the chance of tooth decay.
