Invisalign® is an orthodontic treatment option that corrects teeth that are misaligned, overlapped, gapped teeth, and other types of misalignment issues. Whereas traditional braces adds pressure on teeth using wires and metal brackets, Invisalign® utilizes a series of transparent, plastic aligner trays. Aligners are expected to be worn for 20 to 22 hours a day and should only be discarded while eating, brushing, or flossing your teeth. Many Invisalign® patients often remove their aligners on special occasions. As long as you adhere to wearing your aligners for at least 20 hours per day, Invisalign® will straighten your teeth.
