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.

I really loved the Crest 3D products. I could tell a difference in the color of my teeth in just one use. I would recommend this product to anyone. Great Product and worth every penny! (Posted on 01/10/2011)

I used to be long time smoker and am still a coffee drinker so my teeth are not as white as I would like for them to be. But after using this product just once, I noticed a huge difference. I had noticed myself smiling more, and so did others around me. They couldn't quite put their fingers on it, but knew SOMETHING was different about me. it makes me feel so much better about myself, with just a hint of mystery. (Posted on 25/09/2011)

...the lower strips are too short. It would have been nice if they were as long as the upper strips. (Posted on 25/09/2011)

I have used other Crest Professional Whitening strips with great results. These are a big dissapointment. I like the stickiing power. But I'n not seeing much whitening from them. (Posted on 15/09/2011)

I have been using the Crest 3D whitestips now for 6 days (2 times a day) and I have seen little results. I am a smoker and thought I would try it because I want to make my teeth whiter. I will finish this product but as of now I would not recommend this product to my friends. It is expensive and does not give good results. (Posted on 10/09/2011)

I have been a regular user of Crest original white strips. Now that type is discontinued, I decided to try the Professional Effects 3D whitening strips. I figured, for $50, they should work, especially since the original strips worked great.
After 1 box, my teeth are dingy and discolored. My teeth before were white already, I was just trying to keep them white from using the regular strips 5 months ago.
I understand that the originals had an issue with the strips being slippery and the new ones fixed that. But what happened to the whitening gel?? It's like its non existent on the strips! If only Miejers would grant a refund on a used products :(

I bought these strips in hope of a professional level whitening experience. I don't smoke, drink staining liquids, or have any other discoloring habits. Just looking for something a couple shades whiter. However, a whole box later and my teeth are just marginally whiter. Not sure whether or not it was worth the $45 but if you want to see a slight noticeable change, give em a try. (Posted on 05/09/2011)

Decided at 62, the teeth needed to be brighter and tried the 3D for the first time. Not having anything to compare to, I am happy with the results, definetly whiter, but would like to give it another treatment soon to make them even brighter. I know I'll get good results, but how long should I wait for the second treatment? (Posted on 27/03/2011)

I was pleasantly surprised by the results I got with this product! I have tried whitening strips in the past and not seen any noticeable differences, but i have a big event coming in two days so i decided to try one more time. my teeth are visibly whiter! yeah! i would like to see if i can get even better results by using them one more time before i go to this party--is this safe? i noticed the box says use once every 3 months.....

I bought this product last night and tried it out today. It does work, however I would have liked to have seen a bigger difference for the amount of money spent. I may do another treatment to see if I can get better results. I am overall happy with the product. (Posted on 20/03/2011)

I myself have not noticed a difference after using this product. However everyone around me has been asking me about what I have been doing different. I have read a lot of the reviews on here and am beginning to wonder if some of people who are not seeing the results are just having the same problem I am. I mean if people that didn't even know that I was doing anything to try to whiten my teeth are noticing a difference maybe that really says something about this product. (Posted on 10/03/2011)

I've done the Classic (14-day) strips in 2004, so I thought I'd try this. To my surprise there were 4 sets of strips in the 2-hr box...so although it's 40 quid - you're paying for a YEAR supply . So my husband and I both tried it at 10pm. I flossed and wiped my teeth dry as someone suggested. They stuck like GLUE, unlike the classic set. When we took the strips off at 12, we didn't see any real difference. The next morning I did see some whitening, but not a DRASTIC difference, and my husband's teeth still had no difference. I don't think we would purchase this product again. I will stick with the pro line or the longer day boxes. (Posted on 01/03/2011)

I have used all of the Crest whitestrips in the past... my fave: "Advanced Vivid & my teeth reacted very well...shades whiter...I'm not sure what happened with the 3D Whitestrips 2 hr. express, but, my teeth did not react at all... I'm a avid user of Crest Products but these strips are not working for me. (Posted on 28/02/2011)

I had been wanting to try a whitening system for a while...I didn't see a noticeable difference. I don't drink coffee, or coke and have never smoked so I had hoped for better results. I'm not giving up on your brand I plan on getting a different version to see if it will give me some results. I use many of your other products (Tooth brushes, paste, mouthwash) (Posted on 11/02/2011)

Years ago I used a Crest Whiting product and had phenomenal results. This time around I decided to go with 2 Hr Express and was hugely disappointed! I would not recommend this product and would not use it again. Next time I will use another one in the line NOT the 2 Hr Express.

This is the only disappointing product of the Crest Whitening line that I have used.
After wearing the product for the 2 hours, I saw about as much difference as when I used a single foil pouch of the Pro Effects.I would recommend that you buy the pro effcts from the begining. (Posted on 26/01/2011)

I decided to try 2hr whitening strips for a wedding that was coming up in a few days. It looked like it was whitening while the strips were on but after all the gel washed away I noticed a bit of a change but I expected a lot more for the money. I am going to try professional effects whitening strips because they have a much better rating. Hopefully those work better. (Posted on 17/01/2011)
