Orthodontics can be done at age 36 as long as periodontal conditions allow it, and orthodontics has no age limit. Although adults have less room for jawbone development and periodontal cells are slow to respond to orthodontic forces, it is possible to take a more gentle orthodontic force to pull the teeth to move, so that the teeth are slowly aligned. It is important to note that adult orthodontics begins with a dental exam, which is performed only after confirming that there are no other oral diseases. Adult orthodontics generally takes a little longer than teenagers, taking 2 to 3 years. The cost will also be a bit higher than teenage orthodontics. It is recommended to wear a retainer after the orthodontic treatment is completed to ensure the effectiveness of the orthodontic treatment. If you want to have orthodontic treatment, it is recommended to go to a regular hospital and be guided by a doctor.
