Clean your aligner using your toothbrush and a small amount of toothpaste every time you take it in and out. Once a week use the RETAINER BRITE provided by your Invisalign orthodontist, always following the instructions on the box. Always put your clear aligners into the box provided if you are not wearing them. Placing them into your pocket or a tissue will only result in the aligners being lost or damaged which will incur a replacement charge.
