Just yes. Yes times a million.
Literally saw progress within the first day. My teeth are naturally on the yellow side and most things I use to try to brighten them up don't work all that well. Two uses is all it took to see a slight difference. You have to be careful with how you open it, where you spit, etc. because it's very messy and could end up all over the place if you aren't careful, but if you're careful about handling you should have no problem. Makes my mouth feel very clean, and could he paired with a nice mouthwash to really get your teeth feeling after the dentist clean.
