Invisalign is the invisible way to straighten teeth by using a series of custom-made, nearly undetectable aligners. Upon an initial consultation, Frederick dentist Dr. Nils Olson will decide if Invisalign is right for you. He will write a treatment plan and take an impression of your teeth, which are submitted to Invisalign. Using the latest advances in 3-D computer technology, Invisalign carefully translates Dr. Olson's instructions into a series of precisely customized aligners. You then wear each set of aligners for about two weeks, moving your teeth, gradually - week by week, millimeter by millimeter - until you've achieved the intended result: straighter teeth.
