Like any orthodontic treatment, Invisalign is a permanent solution only if you take the necessary steps to maintain your results. This means you’ll need to wear a retainer as directed while your teeth settle into their new positions. We’ll provide you with a set of Vivera retainers from Invisalign. These retainers look much like your Invisalign aligners, but the plastic is a bit thicker because they’re meant to last longer.
