I was lucky enough to be selected by the Product Review Club to test out the Crest 3D White Whitestrips Intensive Professional Effects.

How well did this product perform according to its advertised claims (e.g. quick results, easy to use, etc)?
These strips were very simple to apply. Each individual package comes with two strips ( a short and a long one). That's it! No goopey mess, no additional product to use. However, I didn't know which strip goes on the top teeth and bottom teeth. The instructions don't mention it. So it was trial and error :( Now, the instructions said to leave it on for 2 hours. I noticed the first time I used it, my teeth started to tingle about an hour into treatment, but I left them on for a full two hours. The next day (I did the application at night), my teeth were fairly sensitive..I've never experienced sensitivity before, so that was a new experience. I decided that I wouldn't do an application every single day. I gave my teeth a break for 2 days and then did another application. So instead of having 7 days, I was able to drag it out for 2 weeks which was good! I noticed a big change about 2 or 3 applications into it. It was a huge improvement!!! I was totally surprised, but very happy to see that my teeth whitened! The only challenge was making sure I had 2 hours free to leave them on. I tried to do the application late at night before bed, so I knew I was going to be eating/drinking or going out.

These strips really work! I was very skeptical but they proved me wrong! To buy the package in the store is a bit expensive. I think I would purchase them for special occasions....weddings, vacations, etc. But if you haven't tried them, get them!

I was chosen as one of the lucky ones to try this product. I was very ecxited about using it and started using it everyday. After the 3rd day, I experienced some discomfort on my gums and my teeth were quite sensitive. I read the label and it did say that this could happen so I stopped using for a few days and resumed using the product every other day. My teeth are much whiter and am so happy with the results of this product!!

I received this for free as part of the product review club.
This product was very easy to use. I did find that having it in for two hours did make the strip come off of my teeth so I had to push it back on but it didn't seem to have a negative effect on the quality of whitening I got from this product. I noticed results after using the first strip. I have used crest whitestrips in the past but they were the cheaper ones and I think I only left them on for 30 minutes. These strips seemed to work much faster than the other ones and gave me a brighter smile right after the first use! I would definitely recommend this product if you want to have quick results without having to pay for a whitening treatment at the dentist. I would probably use this again depending on the price in the future.

I received this product from Chick Advisor's Product Review Club.

I would consider my teeth to be a bit on the yellow side, even though I don't smoke or drink alot of coffee. After the first 2 hour treatment I could already see a change!
It is a bit difficult to get used to the strips especially for 2 hrs, but the difference it made was well worth it.
I would purchase them in the future.

i love this product it is amazing it made my teeth 3 times more white then they were i will deff be buying these again . LOVE IT LOVE LOVE IT :)

I would like to comment and add a review for Crest's 3D Professional Whitestrips. This product is meant to be worn for 7 days straight and the outside box claims that it is as effective as whitening your teeth with laser procedures. So i began the 7 day program. The box and instructions are very easy to understand and read. For 2 hours every day for 7 days straight, you place the upper and lower strips on the top and bottom of your teeth. Crest states that you can drink water with the strips on, and I tested this claim and it is in fact true, no issues at all with being able to drink while the strips are on. These Crest 3D whitestrips as well have a no slip technology called "advanced seal" which as well is a nice feature. I have had no gum discomfort or irritation or tooth sensitivity. I only wish that they could include a color shade indicator to see how many steps you have advanced on the scale. From what I can tell the shade of color I started with has lightened at least 3 steps for sure after the 7 day program. I would definitley recommend this to any one looking at purchasing a teeth whitening program. It is something that doesn't cost a fortune and can give you a much brighter smile with minimum effort. I have tried a tooth whitening strip before but just the occasional one, not a one week program and I have noticed that it is worth buying this product, rather than the occasional one, alot better results. I did receive this product for free to try and I would recommend that everyone try it. You will not be disappointed. Two incisors up!!!

I received the Crest 3D Whitestrips from the review club, I used them for 4 days 1 hour each day, I just couldn`t keep them on any longer as I didn`t really like the taste in my house or the feel of the plastic on my teeth. Even though I did not use them for the for the recommenced 2 hours for 7 days I was still very happy with the results.

I received Crest 3D White Whitestrips Intensive Professional Effects free to test from the produce review club. Ladies these strips do give you a super bright shiny white smile, yet this doesn’t come easily. Your smile will definitely get white after the first day. It is actually dramatic how white my smile becomes after one day of a 2 hours use. The strips are much easier to apply than its contenders, thanks to the advanced seal. The strips are super sticky and will adhere to your teeth extremely well. On the package it states that “you can even drink water while wearing the whitestrips”; although this is true the taste that is left is not wroth it. After using the strips for two days I experienced extreme sensitivity at random time during the day. It felt like shooting pains up the center of my teeth. Given these pains I decided to only use them every 3rd day for 2 hours. Another downside to these strips is the amount of time (2hours) that is needed in order to wear them. When out and about, it’s impossible to wear these strips in public, without people noticing your lisp or the strip. In sum, compared to other strips theses ones stay on better and produce a whiter smile, yet the teeth become more sensitive. This is the price we have to pay for beauty or shall I say whiter teeth.

I received the product for review from the Product Review Club, I must say Im a bit of a sceptic when it comes to whitening products, but these worked great! I did notice a change in the color of my teeth and it wasnt too uncomfortable to wear for the 2 hours. Plus the convience of 2 hours worked out well in my busy schedule. I did not get any sensitivity from the strips although it does state you might. Overall I would definately use them again.

Hi, I was one of the few who were chosen to experience the effectiveness of these strips. I feel that they did what they were made for. For convenience sakes, it was great. I did however have a small amount of tooth sensitivety, so all I did was skip a day and continued on. I will purchase these again in 6 months as it says on the box to do again.
