You can see results just in one use! I have used these on the plane before vacations or before big events like weddings. Easy to use and to travel with.

Crest whitening strips are honestly the best way to whiten your teeth. You can spend money on all the other things but none of it will work nearly as good as these. I have always used them and they are the best.

Although it left my teeth sensitive, this works better than the other strips that also leave my teeth sensitive. The light I think really helps boost the whitening and the batter of the light wasn't a problem.

i love this product because it's helped improve my smile everyday it giving such a beautiful white look from the crest whitening strips! definitely get them if you don't it, it's a need

I love that if I want a quick fix for my coffee stains on my teeth I can just pick up the strip put it on for 10 to 20 minutes and automatically feel so much fresher

This teeth whitening product is high quality for the price point. You get quite a few uses from it and I definitely notice a difference in the color of my teeth

I have tried manyyyy different teeth whitening products! But the crest whitening strips by far show the biggest change. I usually only do them once a year. My teeth are very sensitive, so i use the kit but instead of daily i use it every other day!

I loved these. They made my teeth whiter after just one use which was amazing because I needed them in a rush. However, I would've liked to know that if you have sensitive teeth they might make them sore.

I love crest white strips. I've done several different whitening treatments but none that work as well as crest. And the light, takes it to a whole different level

This is great for someone who is sensitive to in office whitening and cannot tolerate the intensity it comes with ! Using this 1-2 a week leaves your teeth a nice white natural shade with no blotching spots !
