Rinse your aligners each time you remove them to wash away dry saliva and plaque that can result in dental decay and bad breath.
Soak your aligners using denture cleaner, Retainer Brite, and/or the official Invisalign cleaning crystals.
Brush and floss your teeth before you put your aligners back in. Good oral hygiene is key to maintaining healthy teeth and avoiding cavities and decay. Failing to brush and floss properly can trap food debris and bacteria between your teeth and aligner, increasing your risk of dental problems and bad breath.
Clean your aligners with a clear, anti-bacterial soft soap. Clear anti-bacterial soap is an excellent and inexpensive way to keep your aligners clear, fresh, and free from harmful bacteria.
Brush your aligners gently so as not to scratch them, and then rinse off the soap. Then you're done!
