Invisalign is a series of clear plastic trays worn 22 hours a day 7 days a week that will straighten your teeth, improve aesthetics, and functionality. The number of trays varies based on the extent of the movement needed and the arrangement of the teeth for the patient. Invisalign therapy has many benefits over traditional orthodontics such as improved oral hygiene since the trays can be removed and a more discrete look due to the clear nature of the tray. They tend to be more comfortable than traditional orthodontics and can provide some protection for patients who grind their teeth.
