Everyone wants to have healthy and beautiful teeth, thinking that this will make a beautiful smile more confident and attractive. Therefore, a lot of people compare their teeth to their “second face” and use cosmetic dentistry to make themselves look good. Every day, our clinic receives many patients who request cosmetic dentistry. However, many of them have inappropriate knowledge of dental aesthetics, and therefore accept the wrong treatment, and there are many patients who, after dental aesthetics, leave irreparable regrets due to improper use and maintenance of their teeth. Porcelain teeth in the minds of many patients is the universal method of dental beauty. In fact, porcelain dentistry is only one of the treatments given for cosmetic dentistry, and in some cases it is not the best choice. For example, orthodontics should be the treatment of choice for patients with misaligned teeth. That is, the teeth are changed by moving them. If there are flaws in the color, shape of the teeth, full crowns, or veneers can also be used to get an aesthetic result. Some patients believe that it is incorrect to remove a bad tooth and place a denture. Unless the affected tooth has no treatment value, such as loose teeth, wisdom teeth and other cases to consider extraction. We do our best to preserve natural teeth as long as the roots can be utilized. Chasing after celebrities, from time to time, patients will request that my teeth be made to look like such-and-such a celebrity. From the aesthetic point of view of the teeth, due to gender, age, face shape, skin color, personality and many other factors are different, each person is suitable for the shape of the tooth is also different, the doctor in the cosmetic design, need to be based on the patient’s specific circumstances and comprehensive consideration, only suitable for their own cosmetic dentistry. In can achieve the best cosmetic effect. The whiter the teeth, the better, “my teeth do not look white enough, help me make it whiter”. We know that the outer layer of the teeth is enamel, with translucent properties, the inner layer of enamel dentin color yellowish, so that the color of the teeth have a certain light yellow, so the teeth are not the whiter the better, look natural, and their own skin color. A tooth color that harmonizes with your personality is the best choice. Not all teeth within the normal color range need to be made white. Those that are because the teeth are too dark in color and affect the aesthetics will need to be improved with certain treatments. The once-and-for-all thought, “Doctor, if I get my teeth done, I won’t have any problems for the rest of my life, right?” There are quite a few patients who think this way, but once-and-for-all things are often out of reach. First of all, after cosmetic dentistry should also pay attention to careful maintenance, such as pay attention to oral hygiene, avoid biting too hard food with porcelain teeth, etc., but also regular review; second, cosmetic dentistry materials have a certain service life, and the condition of each person’s teeth is constantly changing. Beautiful is important, health should be put in the first place, want to achieve the dual purpose of health, beauty, to be as careful as possible to consult, careful consideration.
