You don’t need to wear braces for the rest of your life after orthodontic treatment. Orthodontic treatment usually lasts for 2 to 3 years, and you need to wear a retainer for about 2 years after orthodontic treatment is over, for the following reasons. Orthodontics utilizes the principle of the alterability of the alveolar bone, and the alteration of the alveolar bone is a slow process, so the treatment time for orthodontics will be longer. At the end of orthodontic treatment, the bone remodeling is usually not yet finished, so it is necessary to wear a retainer to keep the teeth in position until the shape of the alveolar bone is maintained and stabilized, after which there is usually no need to continue wearing braces. If your teeth need to be straightened, it is recommended that you visit a hospital for targeted treatment with the help of a doctor.
