This is an important question to ask your potential provider because it will help you determine the level of training and experience she or he has to make sure they are bringing the best knowledge and experience available to your treatment. Yes, an orthodontic specialist attends a 2-3 year residency *after* dental school to focus only on learning how to properly move teeth using metal braces and clear aligners. Special learning that is not taught in dental schools, such as how to safely move teeth, correct the bite, and grow and development from infancy through adulthood, is carefully studied during this residency. This ensures orthodontists are properly educated and experienced to provide you with the best treatment possible.
