The traditional orthodontic method is to correct teeth by wearing an appliance, and it takes a long time to pull out some teeth. The principle of orthodontic technology is to stick a nail on the surface of teeth, that is, a dental appliance, and then fasten a steel wire on the nail, and use the steel wire to move the teeth and rearrange the teeth. Generally, the orthodontic treatment course is expected to be about 2 years. Although the time is long, the safety is guaranteed. At present, the best way to correct the overblown teeth is the "Meiguan" tooth beauty technology. As long as you come to the hospital twice in seven days, you can correct the ugly teeth. "Meiguan" is a brand-new tooth beauty technology, which breaks through the disadvantages of traditional porcelain teeth, applies professional technology to clinical full crowns of dislocated teeth, deformed teeth and moderate and severe pigment teeth, and finally corrects them with bionic beauty crowns. The whole process of tooth beauty can be easily completed without tooth extraction and pain. The whole process takes only 7 days to correct, and the teeth are firmer after cosmetic treatment, and black lines are not easy to appear after many years, thus achieving a lasting cosmetic effect.
