This whitening strips definitely work very well. The only reason I gave it one last star was because it does make my teeth sensitive. For that reason, I cannot use them every day for more than three days in a row.

This is seriously one of the best teeth whitening systems it always does the right thing and makes my teeth look super white at the end especially after a couple times I would really recommend this to anyone that wants to whiten your teeth for cheap

Don't try whitening your teeth if you have sensitive! I tried it worked, and tooth became white but I had sensitivity on tooth for a week or more after

Al thought these strips made my teeth really white they made my teeth super duper sensitive which lasted for quite a while. There are better alternatives that don't do that for me.

These actually do work! The box comes with upper and bottom teeth strips. Just put them on about 30 minutes and remove them. After a month you'll notice the changes. Your gums might be sensitive after a few uses but it passes. Try them out.

i have used these whitening strips since i was a freshman in high school and i am now a sophomore in college! my most asked questions are how i maintain my teeth so white and my answer is these!!

I love these so much. Sometimes I'll throw a few in my purse so I can use them on the go or while I'm running errands. Leaves my teeth looking flawless

I use my whitening strips everyday and absolutely love the way they make my teeth look. Before using my strips tho I love to go in with this tooth paste for the best results!

Crest 3d whitening strips are the only type of teeth whitening I like to use. They have been approved as safe by my dentist and as you can see in the picture they have improved my teeth.

I like these but they give me a lot of sensitivity which I don't like. I follow up with Sensodyne which seems to help enough but I wish they would put some helpful ingredients in there so I didn't have to use a whole other product.
