No. Thanks to the removable nature of the aligners, you can eat and drink whatever you want while in treatment. In fact, you’re required to remove your aligners to eat and drink. So, unlike when undergoing traditional treatment using wires and brackets, there is no need to restrict your consumption of any of your favorite foods and snacks unless you are instructed otherwise by your doctor. Also, it is important that you brush your teeth after each meal and prior to reinserting your aligners to maintain fresh breath and proper hygiene.
