These Pro Level Whitestrips are super easy to use. I asked my dental hygenist which products work and she suggested these after my cleaning. Boy was I happy with the results! I used them for a little over a week until I was happy with the brightness and now I get compliments all the time! I just repeat after every cleaning for 2-3 days to maintain. Highly recommend!

I bought these for my husband who decided to whiten his teeth after using chewing tobacco for 17 years. His teeth were actually stained brown. Within 1 day we saw a difference, and by the time he was finished there were 17 years of chew tobacco stains completely gone. Fantastic, impressive results!

I was amazed at how quickly this product got my pearly's polished and white. I noticed immediate results! I used the trio of the strips, the toothpaste, and the mouthwash and have to say it is the perfect way to get a glowing smile - fast. Is it wrong that I actually looked forward to using the products each day? I must say, it's quite satisfying to watch your teeth become a mouth-tastic masterpiece. Whether you are getting prepped spiffy for a date, have a reason to celebrate or need a reason to start smiling more - these strips will give you the confidence and the results you need. I would not use any other product!

I love how the Professional Effects White strips adhere to my teeth for the whole 30 minutes. This allows me to continue multi-tasking, while easily whitening my teeth. I also love how I notice immediate whitening effects after using the products only a couple of times. I would totally recommend Crest 3D Whitestrips and plan on purchasing these for my sister for Xmas. #3DWhite

I had not visited my dentist in years and he told me that my teeth looked better than people he had coming in twice a year. I told him I had used the Crest 3d White Strips. Before I used these he had warned me years ago that I had some staining that would never go away. I showed him. These work...I had mild sensitivity but nothing too bad. Definitely will be going to get a new box soon.

I love this product and don't know where to begin! I love the fact that it makes it look like you have had a professional whitening at a really great price. I don't get the sensitivity with Crest 3D like I have with other products. I can't be without these white strips!

I wanted to whiten my smile before the holidays, i drink a lot of tea, so i purchased 2 boxes of the Professional effects white strips. Thinking that if i used two boxes back to back i was sure to have a whiter brighter smile, WRONG!!! I have used them and honestly I can't tell a difference and neither can my husband and family. My teeth aren't horribly dingy but they aren't bright white either, I don't understand why they didnt work. So needless to sayi just wasted $80.

The new crest professional white strips are the best thing ever made!!! I noticed a change in the color of my teeth within 3 days.My family & friends all noticed & asked what I was using.They are so easy to use & they stay in place & do not slide off.I can not believe how well they whitened my teeth.

[This review was collected as part of a promotion.] From the first strip it worked. Packaging is great nice and small. Price is great because it is super affordable. I noticed that the strip needs to be placed on teeth and not the gums. However, it didn’t make my gums that uncomfortable. It worked and beats from going to pay 100s of dollars.

Crest 3D Whitestrips are definitely effective, and they work fast to make teeth super white. The only draw back to bleaching teeth is that your teeth feel sensitive for a bit after (no hot or cold drinks for a day or two) but the dazzling white effects make it worth it, and it's much less expensive than going to the dentist for the same thing.
