I love how easy these strips are. I definitely noticed my teeth looking brighter within a few days. The only drawback is that it does add some sensitivity to my teeth. Love how easy they are to apply and how many stores carry them. I feel like they are a little pricey but they do work well.

Pretty good ans made my teeth really white. However, giving it lower rating cause it makes my gums feel sensitive and my teeth hurt. So… I don't feel like it's worth it in terms of my dental health. Hoping to find something that works a little better. But I do like crest a lot!!!

I've used the leading up to my wedding day and my smile was beautiful and white and bright. This brand is the one my dentist office sells and recommends. It's so convenient I can find it in stores so I don't have to go to the dentist every time to get it!

I've been bleaching my teeth for the better part of the last ten years and Crests Professional Effects have superseded everything I've ever used. I still remember when even Crest made the slippery, difficult to Stick on to your teeth whitestrips-but they still worked and gave me a beautiful smile, which kept me coming back for more. Fast forward to now and I always recommend Professional Effects whenever someone asks me about or comments on my teeth (which is quite often because I'm diligent with my teeth whitening). Although I'm now torn between trying the new Luxe Flexfits that are branded as "the whitest white" or staying with my traditional PE's, I know either way I'll be completely happy with my teeth. Also: I have extraordinarily sensitive teeth but I haven't had a problem with using Crest whitestrips at all, which is why I'll stay loyal to my favorite brand for dental care. Try the 3D toothpaste and mouthwash. I use them all year round and love both products as well.

They work well for some moderate discoloration and are good because they don't make my teeth painfully sensitive after using them. They are a little pricey but carry much less of a cost than professional whitening, plus you can conveniently do them at home and in less time without any trays or messy paste.

I'm 67 years old and used this whitening product because of an article I read in AARP's magazine that suggested ways to be appealing to your grandchildren. One of the suggestions was that you whiten your teeth. I'd been thinking about it previously so this article was the impetus I needed to buy the product. The effect is great! I plan on doing the strips every year from now on!

I can't believe the whiteness after 1 use! So easy to have white teeth in just 30 minutes. There might be some sensitivity for a short period of time after. Ultimately, there's nothing that tops these whitening strips. Everyone needs to smile confidently!!! :)

I actually faithfully keep coming back to these white strips. I'm a pack a day smoker and I drink coffee all day long. Everytime I notice my teeth are looking dingey I use these strips for 3 or 4 days. My teeth are always back to white for a few months after that. They taste a little strange, but they stay on your teeth and the gooo rinses off easy when you take the strips out. I love these things. Totally reccomend.

These definitely help whiten my teeth after just a few uses. My only issue with them is the price, but for the results it worth it. I only use them before I have an event like prom and usually do it the 14 days before and they stay white for a little over a month after!

I've been using these for years! Every couple of months I buy a box and two weeks later my teeth are pearly white! They're easy to use. The taste isn't bad. They're also great if you have sensitive teeth. Some of the other whitening products hurt my mouth, especially my gums.
