Is alcohol-free, sugar-free breath spray okay to use with invisalign? I ask this question because even with brushing and flossing after each meal I get dry mouth and slightly bad breath. I drink water frequently to help with this but I would like to have something to freshen my breath that won't require me to take out the aligners each time. This breath spray is just a little squirt bottle that I can stick in my purse. Otherwise, would sugar-free breath mints be okay?
