Learn How Invisalign® Works

Invisalign is an orthodontic process that uses what are called clear aligners. They’re plastic sheaths that fit over the teeth. You get a series of them. Each one is a little different. Each one moves the teeth about a quarter of a millimeter. And you can align crooked teeth, make them straight, and give you a straight, healthy smile.

The way that the procedure itself works is we either take an impression. Or we’re actually upgrading to where we can just scan the teeth with a scanning device and email that information to the Invisalign company.

They do a computerized treatment plan which predicts where the teeth will move, how they’ll move, how many aligners it will take to do the treatment plan. And they send that back to us in what’s called a ClinCheck, which is a computer simulation of how your teeth will move.

It tells us how many aligners you’ll need. And since each aligner is worn one to two weeks, it tells us about how long it’s going to take to complete the Invisalign treatment. Once it’s completed, you just need to wear retainers at night to keep the teeth in their proper position.
