Hello, if you are undergoing correction, the general doctor will make an appointment for you to come back once a month to one and a half months. If you have completed orthodontics and are now in the maintenance stage, you don't have to go to the hospital for a follow-up visit for half a month to a year. Dental orthodontics must pay attention to oral hygiene and cleanliness, pay attention to brushing teeth, avoid the formation of gingivitis, and avoid food residues staying on the appliance. I hope I can help you!
