This is my preferred method of teeth whitening. It is obviously not professional grade, you really need a dentist for that or at least a UV light. However they are comfortable and convenient and they do work if you keep using them, rinse regularly and cut back on things like coffee, soda etc.

I like these whitening strips. The result time for me to notice a big difference was two weeks (on top of cutting down on coffee or taking it down to one cup a day and immediately brushing my teeth after drinking coffee). This doesn’t feel harsh on my gums either.

Work very well as directed, the strips are very comfortable and low profile. I’ve tried store brand strips and these are worth the extra. I always brush with an enamel strengthening toothpaste for a few brushes after and it helps eliminate sensitivity

I got the crest professional white strips as a quick fix for my dull & slightly yellow teeth. I'm a big coffee & sweet tea drinker. The product does its job, it works really well actually. BUT it makes your teeth very sensitive, when I breathed cold air it hurt my teeth, so yes it does work yes I do recommend it but be cautious, I'd recommend getting some sensodyne toothpaste as well.

I find many options in whitening strips to be a tad expensive. When using I have to make sure I will not need to talk for awhile. Any movement talking etc. tend to move the strips and they begin to raise up and are not as effective. Product does seem to whiten teeth when used.

Noticeably whiter teeth after 30 days! It is kind of weird to feel the strips on, but after getting my results, it was totally worth it! If I had more money, I'd buy it again! Does not cause any new sensitivity problems and it does work well! This is what was recommended by my dentist friends!

I started using Crest 3D White Whitestrips, twice a year, for the last three years. Every time I visit my dentist, he expressed his amazement at the whiteness of my teeth. I had to have a porcelain crown made for a molar that has caused me grief since I was 17 years old, and the dentist struggled to find a porcelain white enough to match the rest of my teeth! Of course he was eager to find out what I'd been doing to keep my teeth so sparkling white, and I was more than happy to tell him Crest 3D Whitestrips Pro Effect :)

This product is really great if you have somewhere to be and you want your teeth to be whiter or as something that you do maybe just twice a year for  generally whiter teeth but I recently stopped using this product because I noticed that my toothpaste was doing a really great job of whitening my teeth and this product might not be the best for your health so I don’t use it that often.

I think this is the kit I use. I typically use these right before a big event so not necessarily they’re “intended continuous use” that is how you’re going to get really noticeable results. But it definitely takes the edge off and I have gotten compliments on the whiteness of my teeth.

The hype for this product is crazy so I was excited to try it out but found them to be disappointing. I didn’t notice much of a change in my teeth color and found that the strips don’t extend far enough back to get some of my teeth on the back/sides. They did leave my gums/teeth a bit sensitive after use but the sensation did fade away after a few hours. I would not buy these again :/
