1.Brushing with force will bleed Explained that tooth bleeding from brushing is caused by inflammation of the flesh of the teeth (periodontitis), but many people misunderstand that it bleeds because they brush too hard 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 cycle is formed and the area around the flesh of the teeth becomes more and more stained, causing periodontal disease to worsen. On the contrary, when we brush our teeth to bleed, we should brush the flesh of the teeth that are bleeding (inflamed). Usually it will heal in a few days, but if it 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, brushing vigorously for a long time also has adverse effects, it will make the flesh of the teeth shrink and enamel damage, teeth become sensitive, and even cause bacteria to invade the pulp of the teeth, resulting in tooth necrosis. 2, scaling will scaling teeth bad Some patients after scaling teeth sore and soft, simply feel is the money to buy uncomfortable, and found that the gap between the teeth increased, easy to hide food, think it must be scaling scaling bad teeth, wash away the enamel, so that the gap between the teeth become sparse, decided not to scaling in the future. In fact, the general public do not have the habit of regular dental cleaning, some more than ten years may not have dental cleaning, I have also met many male patients thirty-something forty years old before the first dental cleaning, the original because of the wedding photos, was forced by the other half to go to 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 sensitivity, 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 enamel, and the tartar between the teeth cleaned, plus the flesh of the teeth anti-inflammatory, it will be felt that the gap between the teeth increased, do not worry too much. 3, lost teeth do not need to set As mentioned in the previous article, the lack of a large tooth, symmetrical tooth overgrowth, resulting in abnormal tooth 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 the teeth, if we have to lose the teeth, we have to set the teeth to avoid the situation of tooth dislocation. 4, children’s tooth decay do not need to manage General people think that children’s teeth will be replaced, so it does not matter if they are decayed, at most painful to remove teeth. In fact, children will not complete the process of tooth replacement 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 can lead to inflammation and infection of the developing permanent teeth below, so tooth decay in children should not be ignored.
