After trying these, I will never try anything else! You really only need one box and after that, you just have to maintain with good brushing and oral hygiene! I get compliments on my teeth all the time and it’s 100% due to these strips.

Crest has the best white strips!!!!! They work so well and fast I love them and can tell a huge difference even after just 2-3 applications. They stick really well and are easy to apply and take off.

I love the results! Although sometimes it makes my gums blister if it touches them! I also have super sensitive teeth so I can also feel burning in my nerves!

These are so easy, cost effective, and do the job. You can put them on and do other things right in your home. My teeth instantly looked whiter after the first application! Highly recommend!

Not super effective but good enough, I have calcium deposits though so I had to have a special procedure done since all whitening products made the spots whiter so it was hard to really judge it.

I really liked these at first. They really work quickly but my teeth are far too sensitive for these strips. They don’t taste bad or leave that goo all in your mouth. They whiten fast. I wish my teeth weren’t so sensitive.

these whitening strips work miracles!! i’ve been using them for years and it helps me stay on top of keeping my teeth clean. i also don’t experience any sensitivity when using them!

This product is amazing! I was so satisfied after the first try. It definetly met my expectations. Ive only used it once and it has already made. Big difference in my teeth. Id defiently recommend others to try it.

I smoke, drink tea and coffee, couldn't ask for a better product. Work's great on my teeth. Crest 3D whitening is what I will use as long as I have teeth:-)

In between my professional teeth whitenings at the dentist, I’ll use these white strips for a little refresh. They work incredibly well and are extremely easy to use. I would recommend to others and continue to use personally.
