Taking care of your Invisalign trays is easy and simple. Each morning and night, you should take out your Invisalign aligners and thoroughly clean both your teeth and trays. It’s recommended that you rinse your trays with water, antibacterial soap, and a soft-bristled toothbrush to prevent plaque and bacteria from building up. You should also soak your aligners once a day and rinse them before putting them back in your mouth.
