Yes, but it takes a long time. Because orthodontics is generally in adolescence and adolescence, at this time, it develops rapidly and is the best period for orthodontics. After the age of eighteen, the body has been shaped. So correct it now, rearrange and fix the loose teeth that you have grown firmly. Because the basic development is completed, it is impossible to grow as fast as adolescence, so the time is definitely not short. Moreover, loosening the teeth that have already grown is much more painful than loosening the teeth that have not developed well. Can't eat normally for a long time after correction. Think about it, it should be no problem to go to a bigger hospital with a better reputation. The price will not be too expensive. I hope I can help you.
