Braces are tools that straighten teeth with wires. These wires have to be adjusted by the doctor every few weeks in order for them to work. Unlike braces, clear aligners, like Invisalign, have the tooth movements digitally built into the aligners, so there is nothing the doctor has to adjust. The doctor meticulously designs all of the tooth movements for a patient on the computer before treatment starts. A series of aligners are then made, and treatment begins. The series of aligners allow teeth to be moved closer and closer to their final positions with each successive aligner. So, the doctor never actually has to adjust the aligners, yet you get state-of-the art treatment, from the best provider in the region, for 60% less than traditional pricing.
