I have had my teeth regularly cleaned by dentists all my life, so I assumed that they were as white as they could get. In particular, I had a front incisor that had always been a noticeable shade of tan. After just ONE use of this product, all of my teeth are noticeably brighter, and the tan tooth is now almost indistinguishable from my other teeth. Wish I had taken photos.

Been using these teeth whitening brushes for a few weeks now and I can def. see the difference. My teeth look way whiter. It's nice that it's so easy to use, no goopy trays.

I can't believe how amazing this teeth whitening pen is. I noticed my teeth are definitely whiter. Ive been using it for a week now and loving it. I have sensitive teeth and didn't even affect it. For the price and quality, you can't go wrong with this one.

I really thought this product might work. The peroxide in it bubbles up just like professional teeth whitening solutions. However, I got no results and I'm past the return date. Dang. I hate when that happens

Just got these a couple days ago, I see some difference but I think it's too soon to tell. The product application works great. The packaging was nice and the pens work great. But I will have to wait to see if they are actually whitening my teeth.

Works ok, but agitate gums

Ive Been using this product for couple of days and i can see a huge improvement . Im a coffee addict and coffee stains my teeth . Now i can confidently show my smile to everyone.

Waiting for it to work isn't fun. But it does work. I use mine in the shower and at end of shower I spit it out & rinse.
