Invisalign® uses a series of invisible, removable, customizable clear plastic aligners that are worn over your teeth and move teeth gradually over time into the exact position your dentist has recommended. The Aligners are switched out about every two weeks and are worn for 20 hours a day. Because they are clear and virtually invisible, no one will know you are receiving treatment unless you tell them! Since your trays are custom made specifically for your teeth, using precise calculations and a plan designed by you and your dentist, you can be sure that the final result will be a smile that truly fits you!
