It’s easy to keep both your teeth and your aligner trays clean because you simply take out the aligner trays to brush and floss your teeth. At this time you also clean your aligner trays. This is also simple.
You have some options when caring for your aligners. You can remove them and gently brush them every night with a toothbrush. You can also soak your aligners in denture cleaner, Retainer Brite, or the official Invisalign crystals to keep them clean and sanitized. Another option is to use clear anti-bacterial soft hand soap to clean your aligners.
