I just bought the strips and have already noticed a huge improvement.. I am so glad that I choose Crest for my teeth and the best results.

I used the Professional Effects 20 uses & was disappointed that my teeth only lightened up maybe 1 shade.

These whitening strips are good for a quick fix but I didn't like them due to the slipping off my teeth

I️ used these white strips for about 6 weeks. They made a huge difference! My teeth are so much whiter now!

It does its job! However, your teeth will become more sensitive after using this, so be careful and try not to use it too frequently.

My mom and I use these and they work amazing! Easy to do at home doesn't take too much time and most importantly it didn't make my teeth sensitive!

Love these strips. They are a little pricey but do a good job. I'll buy again and again. I have sensitive teeth and they don't bother them.

The best teeth whitening ever! I swear it turned my teeth white in seconds. It works great, although it's a little pricey

After the 3rd day, I am fully impressed by this amazing product. My teethes are much whiter even my friends have noticed it.

Very good. Makes my teeth super white, but isn't permanent so you have to keep up with it. Also leaves my teeth hurting sometimes.
