Average
I have been using for about 2 weeks. I think it works about average compared to other products I have tried. . I will continue to use to see if I get better results.

Gritty feeling left on teeth was unbearable…
I’m had high hopes for this product but sadly I was disappointed. First, I will say I like the packaging but the product is hard to get it. It’s supposed to be left on overnight but the grit it left on my teeth was not bareable to sleep with all night. It didn’t have a smell or bad taste so that was also a plus. Do I think it did anything after an unpleasant week of slumber? No. It don’t think it worked that well to remove stains.

inally found something that actually works
honestly i was pretty skeptical because i feel like every toothpaste claims to whiten but never does. but this one is legit. it sounds dramatic but i actually feel so much better about my smile now. i’ve been using it every morning and night and the difference is crazy... even my boyfriend noticed how much brighter they look! it doesnt hurt my teeth at all which is a huge plus for me. seriously if your struggling to find a good one just get this. it’s totaly worth it and i’m just so happy i found it.

Easy, No-Mess Whitening That Actually Brightens Yo
This little pen is super easy to use — just twist, apply a thin layer of the whitening gel to your teeth before bed, and let it work while you sleep. It’s a great option if you want teeth that look brighter without the hassle of strips or trays.
