Crest 3D Whitestrips Sensitive White Teeth Whitening Strips, 13 Treatments

These worked well, were relatively easy to apply, and didn't cause me pain. In fact I only used about half the box to lighten to the pale ivory I wanted. Used one of the treatments on bottom teeth only to even out the color. Note that I don't expect or want to get glaring white teeth, which I think looks stupid. So I'll save the remainder and use again in about 3 months.

Whitens my teeth without the harsh effects of a regular whitening strip!! My teeth are important to me and theyre also sensitive!! This doesnt bother my teeth with sensitivity after treatment!!!

Love it. Worked in three days and it hasn't hurt my teeth or gums, usually with the other kind my mouth will be sensitive after the 3rd day but it hasn't.

Easy to use. I saw subtle, but real results after 5 uses. I have only used this six times of the 13 applications in the box. I skipped a couple of days in between uses because I still felt some mild sensitivity after using this three days in a row — so after third use I skipped two or three days in between uses, and this helped. This product has a strong adhesion and you have to pull very hard to get the strips off your teeth! Beware of that if you have any dental work. Directions could be better on the box. I had to look up more info online. It isn't clear when you can brush your teeth or eat around using this product.

I would recommend the full strength I didn't notice until I made it home I purchased the wrong one either way still worth the buy my teeth gradually got white as it mentions on the box

I need sensitive strips because my gums are sensitive to certain chemicals. Even with this product I can only keep the strips on for about 15 minutes.

I believe that they work over time and that you will probably need to buy more than one box to get the results you want...The strips do stay on your teeth well and l had no pain while wearing the strips...I would recommend them!!!

After my second use my bottom teeth are in pain when I drink water. I don't know how this is good for sensitive teeth. I will have no idea about the whitening results because I'm not gonna be able to consistently use this. Time to try a different brand.

I purchased these because my dentist said to try whitening strips before paying for actual teeth whitening at the dental office. I used these for about a month or so. Not much improvement at all. Seem like i would've needed to buy 2 extra boxes to get the results i wanted.

I could only use these a couple days in a row at a time since they caused shooting pain. As such, my teeth didn't whiten much by the time I finished the box.
