As patients, many times in the self-judgment of oral diseases, always take for granted that we should do this and not that, but practice has proven that what we think we are often wrong, such as milk teeth do not need to be treated, and kill the nerve as soon as the tooth hurts. In fact, many of the dentist’s recommendations are based on the patient’s symptoms, not necessarily applicable to others, but must be most suitable for you. 1, sooner or later the milk teeth have to be replaced, without treatment can also be? The good or bad of children’s milk teeth directly affect their jaw development, the intake of nutrition of the whole body and the development of permanent teeth in the future. Parents are advised to treat them well for the sake of your child’s healthy and beautiful teeth. 2, toothache extracted and it is good? Some patients usually do not pay attention to the protection of their teeth, and when dental disease occurs and they do not want to treat it, they come to the hospital and want to pull it, and when the doctor does not pull it, they make a big fuss and say that the doctor is not responsible. ② You can’t pull it when you have a toothache, it’s easy to get infected and cause you unnecessary pain. Of course, some wisdom teeth or teeth with repeated inflammation need to be extracted in time! 3.Ask the doctor to shorten the treatment time? The treatment of dental disease needs a certain time, for example, the filling of simple small cavity can be completed in one treatment, but the deep cavity needs to be filled after pacifying and observing no symptoms. After the root canal treatment, some of them need to do crown restoration, which takes time. Some patients who need to do orthodontic treatment cycle may take one or two years and come once a month. A request to the doctor to shorten the treatment time is not conducive to treatment. 4, unwilling to accept root canal treatment, all ask for extraction? With the development of high technology many teeth, especially single-rooted teeth, if after perfect treatment is completely possible to retain, and then connected to a crown on it, completely normal function, but there is a prerequisite is that the root must be intact (can be checked by dental film X-ray). Many patients indiscriminately ask for extraction as long as the root of the tooth, which is wrong. 5. Reluctant to take dental radiographs? Some patients are reluctant to take dental film, they think it is a waste of time, but in fact, the purpose of taking dental film is to understand the situation of root, pulp, periodontal, alveolar bone, etc., which is very helpful to the doctor’s judgment and diagnosis, so for some cases (such as: trauma, periodontal disease, apical disease, caries, interrupted teeth and other certain treated teeth ……) is very necessary and is one of the most common diagnostic tools in dentistry. Some parents lack certain medical knowledge, think that taking dental film children eat line is not good, in fact, there is no need to worry, a small amount of photography is no effect on your child. 6, tooth extraction is bad for the brain? Some patients are very reluctant to pull teeth because of treatment needs (such as orthodontics), they are worried about the teeth through the brain, after the extraction of the brain, in fact, this concern is very unnecessary, teeth grow in the alveolar bone, and brain distance is very far, extraction of teeth on the brain also has no effect. 7. Do teeth with nerves not hurt anymore? The pain of teeth is determined by many factors, many teeth without nerves will also cause severe pain due to the stimulation of the root tip by toxins produced by bacteria, and even cause swelling of the gums, which is often referred to as acute periapical periodontitis and acute periapical abscess, at this time the patient has severe pain, if not treated in time, the lesion continues to develop causing extensive destruction of the bone of the root tip, forming Chronic inflammation, pain symptoms will gradually ease, but this is temporary, once the bacterial virulence increases and your resistance decreases and acute attacks will cause severe pain, bringing great difficulties to treatment.
