Invisalign ® straightens your smile through a series of invisible, removable and comfortable aligners that virtually no one can tell you are wearing. Invisalign trays are removable for cleaning and changing to a new set as your teeth move and straighten over time. As an added bonus, Invisalign trays can also be used with at-home and overnight teeth-whitening systems. Your dentist can review these options with you with a free consultation at any 1st Family Dental location.
