In the clinical also stayed for a period of time, often hear some of the patient’s not quite right about the oral problems of the legend ….. hereby corrected, such as the follow-up new content, one after another to add. 1, tooth extraction, will lead to other teeth loose. Answer: If a tooth is extracted to the extent that it must be extracted, generally speaking, the biggest impact on the entire tooth line is mainly focused on two aspects, the first is located in the back of the extracted teeth will be moved forward, but it is also a very slow process, and a few years may not see a significant movement. The second is that the teeth that correspond to the bite will elongate because they have lost their bite. That is, the crown of the tooth will grow. 2, scaling will wash the teeth loose Answer: Under normal operation, scaling is just to adhere to the teeth to remove the calculus, if the real must be pursued on the teeth caused by the impact, that is, it will produce some small scratches on the surface of the teeth, but this kind of scratches in the polished after the basic can be ignored. Some patients may experience loose teeth and hot and cold sensitivity after scaling because scaling removes the calculus adhering to the root surface and exposes the roots, so they are sensitive to hot and cold stimuli. As for loosening, some of it is due to the fact that too much calculus replaces part of the bone, creating a calculus splint. But many people would think that it’s not good to keep those calculus then. But this kind of non-loosening is also pathological. When the calculus continues to increase, continue to cause bone resorption, when the bone of the tooth is completely replaced by calculus or absorption is very strong, the tooth will fall. 3, when the toothache can not be treated, must be anti-inflammatory pain and then come to see This argument is more do not know from whom, in general, dental treatment is the solution to the pain, if it does not hurt, a lot of people will not even think of going to cure the teeth. 4, the teeth are killed the nerve will not hurt A tooth, if you kill the nerve, just the tooth will not have a hot and cold feeling only, if the root of the tooth is inflamed, there will still be swelling and pain, discomfort. And kill the nerve is only as a step of root canal treatment, not the whole content of the treatment.
