First – I often bleed when I brush my teeth, it must be because I brush too vigorously It has been explained that brushing and bleeding is due to inflammation of the tooth pulp, but many people misunderstand that brushing too vigorously damages the tooth pulp and therefore bleeds. However, many people misunderstand that brushing too vigorously damages the flesh of the teeth, so they bleed. 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, which makes the area around the flesh of the teeth become more and more dirty, and contributes to the deterioration of periodontal disease. On the contrary, when we brush our teeth and bleed, it is important to brush the bleeding (inflamed) flesh of the teeth. Usually, it will be cured after a few days. 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 cause tooth pulp shrinkage and enamel damage, teeth begin to be sensitive, and even cause bacteria to invade the dental pulp. The second one – the gap between the teeth after scaling increases and the teeth are sore and soft, it must be the scaling of my teeth Some patients feel that their teeth are sore and soft after scaling, and they feel that they are paying for it, and they even find that the gap between their teeth increases and it is easy for them to hide the food, so they think that it must be the scaling of their teeth that has damaged their teeth, washed away the enamel, and the gap between their teeth has become thin, and they decide not to do it again. In fact, the general public do not have a regular habit, some may even more than ten years have not been cleaned, I have also met a lot of male patients in their thirties and forties before the first scaling, the original is because of the wedding photos, was forced to go to the other half of the scaling. A large amount of tartar accumulation causes inflammation of the tooth flesh, when the teeth are exposed again after scaling, there will be sensitivity, about three or four days after the degree will be slowly reduced. Scaling is the use of ultrasonic shock off tartar, will not damage the enamel, and between the teeth of tartar cleaning, coupled with anti-inflammatory dental flesh, will make people feel that the gap between the teeth, do not have to worry too much. Third – missing a big tooth, I still have a few teeth, and does not affect the appearance, do not need it As mentioned above, missing a big tooth, symmetrical teeth overgrowth, resulting in abnormal surface contact, affecting the ability to chew and normal occlusal relationship will make the neighboring teeth out of position, shifting into the position of the missing tooth. The increase in tooth space will easily harbor tartar film, increase the risk of damage to other teeth due to the domino effect. The loss of one tooth will cause the back teeth to lose support and the incisors will move out of position and become whistles, which will affect the appearance. Therefore, we have to take care of our teeth and try our best to preserve them. If we have to lose a tooth, we have to place a veneer on it in order to prevent the tooth from moving out of position. Fourth place – children with tooth decay, will be replaced later, do not need to pay attention to the general public think that children’s teeth will be replaced, so it does not matter if they have cavities, at most, if the pain to go to the removal of teeth. In fact, children to 12 to 13 years of age will complete the tooth replacement process, such as premature removal of baby teeth will make the six-year-old teeth out of position, resulting in the molar not enough place to grow. In addition, tooth decay can lead to inflammation and infection of the developing permanent teeth below, so children should not be ignored. Number 5 – Bad teeth in pregnant women are due to the fact that the baby has taken away the calcium from the teeth. Many people think that during pregnancy, pregnant women are prone to bad teeth and tooth decay, must be because of the fetus in the abdomen to draw away her calcium; there is even a patient complained that she was pregnant with a BB on the bad a tooth, and she has a total of four sons, so a total of four big teeth are not there. 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 susceptible to dental plaque secretion of toxins stimulated by red, swollen and bleeding, a phenomenon known as gestational gingivitis; pregnancy, pregnant women’s dietary habits have changed, and also more than usual, eat more sweet, acidic foods, coupled with the tendency to nausea, so easy. Even if a pregnant woman has a toothache, she is usually afraid to go to the dentist for fear that it will affect her baby; in fact, there is no problem with the general examination. However, the first trimester is a dangerous period, can not take X-rays; after the first trimester, the doctor will depend on the need, but if not necessary, otherwise will try to avoid. Sixth – I don’t get x-rays because there is no need for them and they are radioactive. According to the guidelines of the British Dental Association, the average person should have an X-ray once every two years. If you are in a high-risk group, you should have an X-ray every six months. In fact, X-rays can be used to check the hidden positions of teeth, such as gaps and feet, and to detect dental problems at an early stage. However, the general public mistakenly believe that doctors can rely on the naked eye, so there is no need to take X-rays, and X-rays are radioactive, so they should be avoided. When the doctor finds tooth decay with the naked eye, the condition is usually more serious, and X-ray can help the doctor diagnose it early. X-rays can help the doctor to make an early diagnosis. In addition, the radiation of X-rays used in dentistry is very low and will not have any adverse effects on the body. The new digital X-ray radiation is even less than one tenth of the traditional radiation, so we can rest assured. Seventh – the filled tooth will not be decayed again in the future. Generally, patients think that a filled tooth is permanent and will not decay again. However, if 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 easy to turn over over the decay over a long period of time. In addition, tooth decay is usually caused by bad dietary habits and if the situation does not improve, the filled tooth will be more prone to decay. Dentists will also analyze the patient’s drinking habits (Dietary Analysis) to reduce the chance of tooth decay. Eighth – Toothpick is useless because the bad teeth will die sooner or later and the process is very painful. Some patients don’t believe in denture root because they heard from their friends that denture root is expensive, painful and useless because the tooth will die sooner or later and has to be removed sooner or later. In fact, when a bad tooth is so bad that it needs a root canal, it is usually not in a good condition, and the root canal will only try its best to save the bad tooth; and because the root canal procedure is complicated and time-consuming, the cost is not cheap. In addition, even if the tooth is decayed again, it will not be felt and cannot be detected without regular checkups. If you do not have regular checkups, you will not be able to detect it until the tooth is decayed to its foot, so you may mistakenly think that the tooth is dead. In general, dentists will advise patients to protect their decayed teeth and provide regular checkups and care. Ninth – I am too old for braces. Some patients think that they are too old for braces, but this is wrong. Of course, braces for children are faster and more effective because of the developmental period. Adult braces take relatively longer, but it doesn’t mean that they are not suitable for adults; due to work, most adults don’t accept to see people with studs, so they don’t get braces. Nowadays, there are invisible braces, or intra-lingual braces, which can help these patients. Tenth–Doctor, please help me to set my teeth better (all teeth mouthpiece), I want to be able to bite bones, peanuts. Some of the elders, due to the deterioration of all their teeth, ask for full dentures, but they want to have real teeth that can be used for biting hard food such as bones and peanuts. I have also met many patients with such requirements. Just as patients without feet with prosthetics, can not hope to be able to run the same, in fact, the whole mouth tray because no real teeth support, chewing power greatly reduced, more likely to shift and loose, playing begging may also fall out. Fortunately, dental implants can greatly improve this situation.
