Follow your recommended oral hygiene plan. For most people, that involves: - Brushing your teeth after each meal using a soft-bristled manual or electric toothbrush. - Using toothpaste containing fluoride to help your teeth stay strong. - Flossing daily. Also, follow any other home care recommendations from your dentist. As you can see, you brush and floss as normal after removing the aligner. You will want to take special care to remove all food debris from your teeth after each meal before putting your aligners back in your mouth. Also, you will need to keep the aligners clean.
