Adults may need orthodontic treatment for a number of reasons, such as:
To improve the appearance of the teeth and face
To improve the health of the teeth and gums
To improve function and make it easier to eat
To facilitate restorative treatment, such as implants, veneers, crowns, and bridge work
To combine orthodontics and orthognathic surgery in adults who have finished growth
As the adult mouth is fully developed, the bones are harder. It is likely that treatment will take longer to successfully adjust adult teeth than in younger patients.
