What is Invisalign®?

The Invisalign system uses clear aligners made from a specially developed thermoplastic material. These custom-made aligners are designed to slip over your teeth and essentially “disappear” once in place. Invisalign moves your teeth into alignment in a staged sequence that’s determined by your dentist.
