Crest3DWhite Teeth Whitening Pen, Easy-to-Use, Conveniently Erases Surface Stains, Teeth Whitening Products

I like this a lot. I use it every night.

Works great for daily use and not too strong

Works well & cheaper than in local stores but can get better deals at warehouse discount stores I.e. Costo or Sam’s Club.

I don't know, in my case I think not, but maybe I don't know how to use it correctly? You are supposed apply it to your teeth but then not close your mouth for a while which was impossible for me. Try holding your mouth open for ten minutes, not getting your teeth wet, and you're going to end up drooling like a big old dog. Must be some method I don't know but I didn't have any success. Still I'm putting my rating at 3 stars because maybe it was user error.

I don’t know much about dentistry or teeth whitening but my dentist does and this is what he suggested I use. Works great and boosts my confidence

I didn't wanna spend $50 on the whitening strips and this was a great and quick way to whiten. The first time I applied it I could tell a difference

I needed a quick fix for coffee/tea stains and this pen did/does the job when used as directed. I was surprised when I found that out because I expected just more hype about teeth whitening, etc. It's a good item to have in my purse for quick use & I like that above all. I'm sold on using this pen.

Doesn’t work
