Unlike braces, your Invisalign aligners can be removed. However, if you don't wear them, they won't work. If you don't wear them enough, they won't work well. We find that most patients can eat any diet they choose during treatment. However, we do recommend you avoid foods that will stain your trays, like curry, turmeric, and yellow mustard. If you must enjoy foods that stain, we recommend you do so on the last day you'll be wearing a tray.
