Leaves my teeth feeling clean unlike most clean toothpaste. Really enjoying it so far!

My teeth at age 59 have become many shades whiter. Easy to use, taste is not bad, and no sensitivity. However the pen itself seems hard to wind up and when it does too much comes out and ends up in the cap.

I'm pleased with this. It doesn't feel too harsh, but I still notice a difference in the shade of my teeth.

Had it for a few weeks now haven’t seen a big difference in my daughter teeth but she do love brushing her teeth now

I do notice a whitening effect when consistently using the whitening pen in combination with the berry flavored anti plaque spray.

I drink coffee everyday and this pen made my teeth a few shades whiter in just a few uses - truly AMAZING!! Thank you Dr Brite!!

Although easy to use, didn’t see much improvement on the whitening. I prefer the other Dr. Brite teeth whitening product.

I have tough stains so I'm still working on it.
