Crest3D 1 Hour Express White Strips Dental Teeth Whitening Kit, Lasts 9 Months & Beyond, 7 Treatments, 14 Count

I love these strips, they work very well. Item came exactly as described.

I tried a cheaper brand here on Amazon and went back to Crest 1-hour White Strips. If you leave the strip on longer than one hour -- better results. My 55-year old teeth look nice and white using this product. You'll pay more, but you get better results.

I’ve used these strips for years now. I try to always keep some on hand for when I feel like whitening. They always do the trick and really do whiten teeth as they say.

I was initially very skeptical about buying these because let's be real..how well can whiting strips really work?? I'm so glad I didn't allow that negative thinking to stop me from buying this because I would've missed out on my best smile! You wear these for 7 days, once a day for one hour. After the first application you can already see a difference. I'm truly truly surprised but will definitely keeping coming back for more.

The box was squished when I got it

I am an avid coffee and tea drinker, my teeth are never as white as I'd like. Ive used whitening strips for years and these are the best. Try not to use right after brushing but make sure no plaque is on the surface of teeth. Works beautifully, teeth are shades lighter after one use. If tooth discomfort occurs, stop using and try again in a week.

Used these twice so far, once per week and I definitely see results !Not sure how often they are supposed to be used but I can’t wait to give it another go!
