Great!
I’m new to whitening products so this is my first experience with these items. On the first use I did see a difference in my teeth maybe like 1 to 2 shades. However since it’s my first time using whitening products I wasn’t aware of how long I supposed to keep my mouth open for went to rinse out I want to brush so that was a learning curve. However I’ve had mouthguards from previous aligner treatments so I’ve use that to keep my mouth open. It can get a little messy, but I think it’s definitely worth it and best thing is that there’s no teeth sensitivity! Flavor, is good, it’s very faint, but in a good way.
