Does Food Residue Stain the Aligners?
You will be removing your trays before you eat. Then, before you put them back in, a complete brushing of your teeth is important, because foods like pasta sauce and berries can stain your aligners. Remember though, you will be getting new trays every few weeks, so not all is lost if you get a stain. Your trays will still work as you wait for your new set and promise to keep them clean and clear.
