Invisalign is a more discreet way of wearing braces. It is a series of clear trays that are worn for around 22 hours a day and removed when eating or to clean teeth. These clear trays help move and align teeth to their normal position. Trays are often switched once every 2 weeks. Invisalign can help in treating patients with different malocclusions like moderate deep overbite, moderate to severe crowding, rotated teeth, open bite, cross bite.
