Recently, on how to solve the problem of unattractive adult teeth, the term “cosmetic crown” has frequently appeared on the Internet and some media magazines, and some related medical institutions claim that this technology can quickly improve the aesthetic problems of patients’ teeth, but also can eliminate the pain of wearing braces, and has a trend to replace conventional orthodontic treatment. How to understand the “crown”? Generally speaking, the aesthetic problems of teeth include: irregularities, tooth defects, abnormal tooth color, etc. If it is only the shape and color of the teeth themselves that are abnormal, the most common method we take is to wear porcelain crowns or veneers, which will not actively destroy the pulp part of the teeth, such “cosmetic crowns” are acceptable; if it is simply If we cater to the concerns of patients (wearing orthodontic braces affects the aesthetics, orthodontic treatment is too long), the pursuit of rapid changes in the alignment of the teeth, and enlarge the indications of the crown, it will bring patients more losses than gains. An unaligned crown means that the roots of the teeth are also not in their normal position, and to move them, they must now undergo a slow orthodontic procedure. To make the patient’s teeth straight within a week or two, it is inevitable to make a “big move” on the severely misaligned teeth – drilling open the crown, killing the nerve, and then making a porcelain crown to artificially align the patient’s teeth, and in most cases the patient’s gum margin cannot be The long-term results are not ideal. To use a figurative analogy, a row of inconsistent trees, in order to make them neat and tidy, artificially trim the tops of the trees, or even cut off all the crowns, and then uniformly put on a fake coat, will that be natural? Therefore, for adults involved in aesthetic problems such as facial dysbiosis, the correct measure is to prefer orthodontic treatment, which can be combined with plastic orthognathic surgery in serious cases. As a dentist with professional ethics, when facing an adult patient who comes to consult about unattractive teeth, he should provide the patient with a reasonable treatment plan; and as a patient who loves beauty, he should also learn more about the above mentioned scientific knowledge before receiving treatment, so that he will have less regret pills!
