How Do You Prevent Invisalign from Getting Discolored?

How do I keep invisalign aligners clean
While you may drink water with aligners on, you should not have colored drinks, coffee, soda, wine, etc while aligners are on and always brush or at least rinse before putting aligners back on. You may also use a tooth brush to clean the aligners with water. There are cleaning tablets you can purchase from your pharmacy and one crystal especially designed for invisalign. Simply google search: invisalign cleaning crystals
Overall, since aligners are changed every two weeks, you should not be overly concerned with stains, etc.
