I received this product as part of the Chick Advisor Product Review Club. I have been wanting to try these for a long time, I just could never justify forking over the cash!! I started the regiment immediately after receiving them in the mail! I did find that after the two hour application my teeth were a little sensitive, but that did eventually go away. The strips went on easily and came off easily. The hardest part was finding the 2 hours to wear them for. I did notice pretty good results even after the first application but I was hoping they would be a little bit whiter and brighter. But still not bad at all. I have had many comments on my teeth and would definitely recommend this product. After using it I would say to others unwilling to fork over the cash like I was to try it, It was well worth it for me and I will be buying them again in the future there is no doubt about that!!

I just bought this because i just want my teeth whiter, yes i am a smoker and unlike other strips ive tried, these ones stay in place, they dont taste gross, you can honestly forget about them once you have them in. I found the other brands dont stay and they taste very bad because they leak. This product is amazing, i love how effective they are, i literally forgot i had them on, you can even drink water with these on and no bad taste or anything. Overall i am very please and I noticed my teeth were whiter after ONE USE! unbelievable.Also did not experience any pain whatsoever.

AMAZING product. i would defiantly buy this again and would recommend it to ANYONE who wants whiter teeth.

There was some sensitivity after the first application, and I felt sharp piercing sensitivity in one tooth a couple of times that thankfully didn't last long. They stayed on fine, and there wasn't a terrible taste. One of the things to keep in mind about this is scheduling when to apply them, since it's for 2 hrs. (ex. I didn't eat or drink while they were on.) I purposely didn't use whitening toothpaste while using them. My teeth do look a bit whiter, but I took before & after photos, & there isn't as much of a difference as I expected really. I tried regular Crest whitestrips 5 years ago with the same results I'd say.

I was so thankful to be chosen as a tester and the timing was fantastic just before I had to attend a wedding! My smile is whiter and brighter! People were commenting on my pearly whites and asking how I managed to keep them so white and bright! Who knew what magic could be done in 7 days! This is a must have!

I received this product as part of Chick Advisor's Product Review Club and was very excited to try it out. I had occasionally used whitening toothpastes and had once tried another brand of whitening product, without much success.

As soon as I received the Crest 3D White Whitestrips Intensive Professional Effects I opened the box and read the directions. The instructions were very clear. The only thing that wasn't initially clear was whether or not they were to be used for 7 days consecutive days. (they are to be used consecutively)

The strips were extremely easy to apply and remained adhered to my teeth for the entire two hour whitening session.

I did feel a small amount of sensitivity on my lower teeth towards the end of the two hour period. The instructions had made it clear that this could be a side effect. The sensitivity resolved within a few hours.

The strips removed easily and I was thrilled to see that there was a noticable difference after only one application.

At the end of the seven day period, several people had commented on the difference in my teeth.

The whitestrips were easy to apply, and had minimal side effects (mild sensitivity). The results were very noticable. I'm not certain as to how long the results will last, but I will be purchasing these again.

I was very excited to be selected as a tester of Crest 3D White Whitestrips Intensive Professional Effects by the Product Review Club, which was shipped to my door for free.

As a frequent drinker of things that are known to stain teeth (coffee, diet coke), I found myself with moderately yellow teeth. Even after a recently cleaning at the dentist and my continued use of whitening tooth paste I found my teeth lacking a certain sparkle and shine. Needless to say I was in need of some whitening.

I've whitened my teeth in the past (2-3 years ago) and found that faced with the options in the drugstore, I was only willing to pay for some of the lower end products and was given lower range results. I hoped to learn that the new Crest 3D White Whitestrips Intensive Professional Effects would be worth the cost.

The 7 day treatment was very easy to use. The strips peeled easily off the packaging and were applied to my teeth in seconds. One of the major benefits I found with these strips was the advance seal technology which I had never experienced before. Earlier incarnations of whitestrips would slip and slide off of my teeth forcing me to keep my lips off my teeth, mouth open uncomfortable for the length of the treatment. This time I could talk and close my mouth without any movement from the strips. While I didn't test the claims that water could be drank with the strips on I believe it; those things weren't budging.

After the 2 hour treatment time I peeled the strips of my teeth with little difficulty rinsed the remaining gel off my teeth and was done with day one. I've never had sensitive teeth, but shortly after removal I experience some slight pain on the front surface of my teeth. This pain didn't cause me to change any of my habits as I was still able to eat hard, hot, and cold foods and drinks without any additional discomfort. The pain only lasted for the first day and a half, and was very tolerable.

I began to see some slight change in colour after the 2 day. By the end of day 7 I was thrilled with the results. My teeth were several shades whiter and gave me a shiny sparkly smile!

A few minor complaints I will add: My teeth are not 'Hollywood' white after the treatment. The change in colour is definitely worth the effort, and maybe even the price, but I don't think it would cause anyone to complement me on my extremely white teeth. Also, there is a slight gradation of colour on my teeth now with the ends being most white and the gumline slightly more yellow. Again, not a major complaint as I believe I only noticed it since I was inspecting my teeth so closely.

I will keeping this product in mind the next time I need a smile boost. I would especially think this product would be useful for special occasions and will be recommending it to my friends as they prepare for their weddings.

I am very pleased with the final result of Crest 3D White Whitestrips Intensive Professional Effects and am proud to show off my new brighter, whiter smile.

I received this product as part of Chick Advisor's product review club. I was extermely excited to try it out as I've wanted to purchase it in store but wasn't willing to shell out the cash.

The strips are easy to use and adhere well, even to my never-been-braced imperfect teeth. I was a bit worried that some teeth would turn out whiter than others, but the whitening effect was even throughout. I continued to talk and drink water like normal with the strips on, and they stayed one with my teeth throughout the whole two hours.

After my first use, I noticed whitening right away.. they were at least a shade whiter (quite white to start out with). There was a bit of sensitivity but it was nothing major. After using them for the entire week, there is a definite difference. I have gotten quite a few compliments on how much whiter my smile is. It is definitely a confidence booster and makes me want to smile more! Thank you Chick Advisor for the wonderful opportunity! I will definitely be re-purchasing this, and it is well worth the price.

I was very excited to try this product! The instructions were pretty straight forward and after a little bit of aligning, the strips were easy to use.

You may notice a bit of discomfort or sensitivity like I did near the 2 hour mark, but it didn't last long. After a week, I can honestly say my teeth are sparkly white and I am really pleased!

I would definitely recommend 3D White Strips to anyone trying to whiten their teeth without visiting the dentist.

I found this product easy to apply and it stayed on my teeth the entire time without issue. I found it difficult to find a solid 2 hour block of time when I wasn't busy or going to eat anything to actually be able to use these. During the process, one of my teeth had a sharp shooting pain through the middle that was excruciating. I ended up taking the strips off 5 minutes early (which I don't think is a big deal) because my tooth hurt too much. I have excellent teeth and have never had a cavity or sensitivity, so I will say that the pain was from the strips, but this is not my first time using Crest whitestrips, so I was expecting a bit of pain. It has been 4 hours since I took the strips off and my teeth only hurt slightly. I did notice that the tips of some of my teeth are completely white, and I'm hoping that will go away. Overall, I would say that these worked only as well as the regular professional effects whitestrips that only need to be worn for half hour.

The thing that really bugs me is that the instructions are written very generally so that they can be used for all Crest whitestrips products. NO WHERE in the instructions does it say how often you should wear the strips. It says that you should use only 7 per year, but does that mean you can wear them all in a week and then wait a year, or should you space out the use evenly throughout the year????

I don't think that I would buy this product simply because I like the Crest Whitestrips Professional Effects (original half hour version) way better and will most likely stick with those.

The strips were easy to use, strips were a bit tough to align properly as my bottom teeth are pretty crooked but no biggie.
After just one application, my teeth were a lot whiter than they were before, and after doing the whole process
and after drinking pepsi, my teeth are still relatively white.
my teeth did feel sensitive while wearing the strips and for a few hours afterwards.The only downsides to this product is that it makes your teeth a little more sensitive and it is a bit expensive.
