It's too late to correct teeth at this age, but it can still be corrected. The biggest advantage of correcting teeth at the age of 35 is that it can correct abnormal occlusion of teeth in time, avoid diseases such as jaw joint disorder caused by malocclusion, and also avoid the probability of tooth disease to some extent. However, it may take a long time to wear a retainer to correct teeth at this age. There is no strict age limit for orthodontics, and patients of any age can receive orthodontic treatment. When orthodontic treatment begins at the age of 30, patients can actively cooperate with the operation, keep the oral cavity clean and reduce the occurrence of gingivitis and dental caries. Compared with teenagers, 30-year-old patients have slower tooth movement and smaller periodontal ligament area, so it is necessary to pay attention to using lighter orthodontic force to activate the cell activity of periodontal tissue. It is best to use intermittent force or extend the follow-up time to provide enough reconstruction time for periodontal tissue and prevent alveolar bone absorption. Adults can do orthodontics without any harm. The specific correction plan has to be confirmed by face-to-face consultation, and there is no inspection on the Internet, so there is no way to determine it for the time being. It may be necessary to have a tooth extracted. Fixed appliance is better, or you can choose both fixed and invisible appliance.
