In clinical work, patients often ask the question, “Are adults suitable for orthodontics?” In the people’s impression, orthodontics is suitable for children in their teens. In fact, the alveolar bone is constantly remodeling throughout life, which provides the basis for adult orthodontics, but the cycle of adult orthodontics is relatively longer, the specific situation will vary from person to person, but the cycle of adult orthodontics will usually be in about two years, of course, without extraction cases will be shorter. There are many adult patients whose teeth are uneven and unattractive, who cannot brush their teeth, whose gums are red and swollen for a long time, and who bleed when they eat apples. These patients listen to the advertisements sometimes use some so-called “short and quick” method, the front teeth into porcelain teeth, is a short time to solve the aesthetic problem. But this solution to the problem will have many potential pitfalls, in fact, porcelain teeth are usually by a certain life, when these porcelain crowns fall off, our teeth have become like a small mouse, in the long run is really not a good solution. With the current development of orthodontic technology, the emergence of new orthodontic tools, but also to a certain extent to meet the requirements of adults for aesthetic, invisible, comfortable, such as invisible braces, lingual braces, ceramic brackets, will play a certain invisible role. Adult orthodontics has better results for misaligned teeth, closing gaps, mouth protrusion, “buck teeth” and other misshapen M deformities.
