Proper upkeep and good oral hygiene are essential in keeping your Invisalign aligners clean, invisible, and odor free. The aligners can be easily removed for eating and drinking, however, failing to properly clean your aligners afterwards can result in discoloration and a buildup of bacteria.
To maintain clarity, it is good to periodically clear debris from your aligners with a soft toothbrush and water, but do not use toothpaste due abrasives that can create micro abrasions that make your aligners cloudy and dull.
DO NOT use denture cleaners to clean aligners or soak them in mouthwash. These products can damage the surface of the plastic, causing it to become more visible, sometimes making the teeth look somewhat yellow.
Do not eat or drink (anything but water) while wearing Invisalign. Many foods and drinks can stain or discolor your aligners. And remember...using toothpaste to clean your aligners will scratch the plastic and dull your aligners. These scratches can also create small traps in your aligners for bacteria to dwell.
