Many patients who need to have their teeth straighten or realigned choose Invisalign as an alternative to metal braces. Invisalign aligners are clear, so they don’t change your appearance, and they can be removed when you eat or brush your teeth.
Invisalign works on the same principle as metal braces, but instead of using springs, wires, and brackets to align your teeth—it uses aligners made of plastic.
The aligners are changed regularly. Each new set is different than the one before it, so over time the aligners realign your teeth into healthy positions.
