Crest3DWhite Teeth Whitening Pen – Easy to Use, Erases Surface Stains – Up to 75 Uses per Pen – Convenient, On-The-Go Teeth Whitening Solution

This product helped me get rid of some nasty stains that whitening strips wouldn't touch because they were more in the cracks. I used to have crooked teeth and the stains became apparent when they straightened out and you could see where the teeth were in front of each other, if that makes any sense. I could slide this brush in all the hard to reach areas! Thank you, thank you, thank you.

Love

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.

Works great I keep it in my purse

Works well!

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.

Dont recommend at all. Teeth feel too sensitive after using this. I regret experimenting with this
