Invisalign The Invisalign System is a virtually invisible and hygienic orthodontic treatment that uses an innovative approach to effectively straighten teeth. With our proprietary SmartForce Technology, the Invisalign System uses a series of custom-made removable aligners created for you and only you. These aligners are made of a virtually invisible plastic that you wear over your teeth to gradually move them to the ideal position. Most people won’t even notice you’re wearing them, allowing you to keep your lifestyle during treatment. The Invisalign System is available through Invisalign-trained doctors who determine the treatment plan.
