When your dentist scans your teeth initially, they'll come up with a comprehensive plan of where they want your teeth to end up by the time the process is over. This involves multiple small adjustments to different areas of your mouth. Every couple of weeks, you'll get a new set of invisible braces that are especially tight around the teeth as each set has its own job and slowly moves your teeth through controlled force to where they should be. Some sets have "buttons” that click onto little dots on your teeth that your dentist applies so that they have better grip as they slowly, gently pull your teeth to where they should be.
