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.

Worked great! I didn't want to spend a fortune at the dentist so I used these instead. I'm sure that the results weren't as dramatic as they would have been at the dentist, but they were good enough for me.

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.

These work great i could definitely tell a difference just after one use. I drink coffee every morning and red wine at night so I definitely needed some help keeping my teeth white.The only reason I give this 3 out of 5 stars is my teeth were extremely sensitive after just one use. Can only do 1 treatment a week. Getting jolts of nerve pain in my teeth the whole next day. But pretty amazing the results, I would say just as good as getting my professional trays from the dentist and ALOT cheaper option.
