Movemints have been a life (and breath) saver! My orthodontist recommended this product on the first day I received my Invisalign, and I have been a hug fan ever since. They have really helped me with dry mouth at work (where I have to talk a lot!) along with freshening my breath. I've also found using them to seat my trays helps to ease the soreness the first few days of a new aligner. If I could give 6 out of 5 starts I would! Buy a pack and you won't look back!
