I would have given 5 stars for its whitening capability. However, it tastes awful, the way I imagine that hand soap would taste if I squirted some in my mouth. Oh, well. You have to be careful, as it is designed to adhere to the tooth surface (of course) and the black charcoal definitely can stain clothing. I use tissue to wipe it off my teeth when done, as I don't want to have a plumbing issue later on if it can build up on pipes. Having one larger syringe for the gel is great. Assuming I will order again (highly likely!), I may try the white gel instead, in hopes that it would be more palatable.

Started to notice teeth getting a little whiter.

I love knowing I can get my teeth white, without putting a ton of toxins in my body!!

I look in the mirror and now, Zoom, and find my smile to look wonderful! I am very pleased with the results of this tooth whitening system, more than experienced with others.

it works
