These crest white strips work wonders! They are very effective, and they are easy to use. The taste is pretty terrible, but it's worth it. I do usually have sensitive teeth for a few days after, but again it's worth it.

I have used crest 3D whitening strips maybe twice within the last 4 years and my teeth are still very white! It stung my gums a little but at first but went away after a few minutes. I will buy them again when I feel the need to touch up!

A little messy and I wish the packaging the strips came in was more convenient. I do feel like I had dramatic whitening after only two or three uses, but I experienced a lot of sensitivity and had to pause using them.

These strips are easy to use and super effective! I definitely see a difference after just one use. They also don't make my teeth sensitive like other brands do. I am very satisfied overall with this product

These really do work and make your teeth so much whiter BUT warning IF YOU WEAR THEM LONGER THAN 30 minutes your teeth will hurt the next day and be extremely sensitive so be careful and don't wear them longer than recommended time

Love these so much! I have issues with teeth sensitivity when using whitening products and haven't noticed much with these. I definitely notice a difference in whiteness when I use these! Highly recommend!

Not as amazing as the ads make it seem but definitely effective. The new technology stays on soooo much better than the old ones, making them a lot more comfortable.

I thought this product worked very well. My only issue was that it was summertime because they having him back and had to be done in order to achieve any substantial change in the color of your teeth!

Great product . You can tell the difference. Helps make your smile look bright if you do it consistently.its effective and the price isn't bad . I'm also a repetitive user ! I'm overall satisfied with this product. Works good if used correctly .

I personally love these teeth whitening strips! They work wonderfully and they don't make my teeth too sensitive which I love. I have experienced sensitive teeth with whitening strips before, but these ones aren't bad.
