What are the advantages of Invisalign?

The main advantage of Invisalign is that it does not hurt like metal braces. Each aligner only moves the teeth .25 millimeters. That small movement is usually done in 1-2 days. It is a controlled, gentle movement. In addition, it is very easy to clean the teeth after eating. The movements are calculated in a computer-generated treatment plan that simulates the movement of the teeth, tells how many aligners you will need and what potential problems you might have.
