This makes my teeth tingle, and it took a couple times to get use to. Otherwise, it's effective and my teeth are 2-3 shades whiter.

Crest white strips always make a noticeable difference in the brightening of my teeth and I use them regularly.

These keep my teeth super white and pretty! I always use them because white teeth are important to me

This is great. It's a little on the pricey side but it's a lot cheaper than getting your teeth professionally whitened.

These work really well. They stay on my teeth and I can keep them on without worry of them sliding. And my teeth always get so white.

these work really really well! they make my teeth super duper white, they do make them more sensitive to cold items though

I use these regularly. Typically my go to for teeth whitening. The only negative thing is they do not feed my teeth well.

I have never seen anything whiten my teeth more than these strips. If you need something quick to whiten your teeth go buy a few of these.

amazing results but not good for sensitive teeth. After a few hours of me doing it I get a very uncomfortable feeling in my teeth.

Great product just wish it was a bit cheaper. Have to keep up with it if not your teeth will stain again. Gets the job done if used correctly
