My teeth are whiter, it works!
I have used this 2x a day for about 7 days now. I notice quite a change in the whiteness of my teeth. The instructions only say not to eat or drink for 30 min but don’t say how long to keep it in. I brushed it on my teeth avoiding my gums and let it set for about 20-30 min until I have to spit it out. It doesn’t taste bad but wouldn’t want to swallow it. I avoid drinking dark liquids after too. So if you are a coffee or wine drinker do it after you drink. I haven’t went through one tube yet and 4 came with it.
