Patient: I want to straighten my uneven teeth. Is it reliable to straighten my teeth in 7 days? Is there any other method besides crown. Thank you! Doctor: First of all, you said the concept of beauty crown, in the classic dentistry textbook does not exist, there are some related oral health care institutions use such a more eye-catching name to attract customers, we can not be too much evaluation 。。。。 Chongqing Southwest Hospital Department of Stomatology Yang Yanchun Simply put, you say the crown, in fact, is the so-called all-porcelain crown —- advantage is the short time, generally about a week to end the treatment. It is by grinding the teeth smaller according to certain requirements, and then bonding the porcelain crowns on the surface of the teeth so as to align the teeth by changing the shape and angle of the teeth. It is very effective for cases of unpleasant tooth color and abnormal tooth shape. In the production of porcelain teeth, it is necessary to grind away part of the teeth, which requires high technical skills and high quality of porcelain dental processing. If the teeth are ground down too much and the porcelain teeth are not of good quality, inflammation and unattractive color and texture will occur. And, for the more serious degree of tooth misalignment, and then porcelain teeth, the need to remove more teeth, and even need to sacrifice the internal blood vessels and nerves of the teeth and other tissues, the teeth should be said to have some damage. Therefore, the teeth are heavily misaligned, crowded teeth are very serious, it is best to align first through orthodontics, and then porcelain restoration, so that the amount of teeth need to grind less, and, the final porcelain restoration effect will be more beautiful. In addition, we often talk about orthodontic treatment, is to align the teeth through the movement of teeth. The disadvantage is that it takes longer, usually about a year, but the advantage is that it is possible to keep your natural teeth intact. The biggest advantage of this method of orthodontics, which does not require grinding and cutting of teeth, but only through the movement of teeth to align teeth, is that the mouth is preserved in their own natural teeth, from biocompatibility, oral comfort and other sensory indicators, are artificial porcelain teeth can not be compared.
