I;m a big tea drinker and I have found that over the years my teeth had lost some of it's whiteness and I really wanted to have the same white teeth that i had on my wedding day, so I bought the 3D white strips to try to whiten them as we were going to celebrate our 25th wedding anniversay and to my amazement it litned them 3 shades of white.

I have used Crest strips on and off for a few years now - the classic ones and these ones. They work great especially if you use them every day for a few days.

I don't always do the 7-day treatment because I find it too much for my teeth (they can get sensitive), however, even after a few days I can tell a difference in the whiteness of my teeth.

They are a little pricey, so I try to buy them when they are on sale. I love using before an event to make my smile ever better.

I received this product as a part of the trial test group. This product was extremely simple to use. As others have commented, the most difficult part is trying to schedule in 2 hours every day to complete the treatment. My only other negative comment about this product is that, because my teeth are not perfectly straight, applying these strips can be a touch on the tricky side. However, that aside, this product works great. After the first treatment I was able to see mild results but, by the end of the week, the difference was definitely noticeable. I think I had expected to see a bit more of a change but, nonetheless, the change that did occur wad definitely noticeable. The only other treatment that I have tried, aside from whitening toothpaste, was the the Crest Whitestrips that you use once every 4 months. Obviously, as this is a more intense treatment, the difference was more noticeable with this trial as opposed to the previous one.

All in all, although a touch pricey, I would definitely recommend this to others and will certainly consider purchasing this product in the future.

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 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.

I received this product through the review club. I was super excited to see i had been picked to try this product....earlier in the month i had been complaining about the colour of my teeth, and this did a great job of noticably changing that.
The strips were easy enough to put on, the instructions were clear and well written. I was surprised to see that I needed to keep them on for 2 hrs. That was the only down time for me. As a mom on the run I'm lucky if I ever get to sit for 2 hrs and wearing them out wasnt an option i was comfortable with. I will say however that i definately noticed a significant change and I would buy them again to keep my teeth this colour.

I received the Whitestrips free from the ChickAdvisor product review club.

After the second usage, I started noticing a visible difference. After the full 7 days of usage, my teeth were definitely whiter. My teeth had coffee and tea stains, but after using the Whitestrips, my teeth were white again!

I had sensitivity from the first day's usage, which remained until a day after I finished using the Whitestrips. It does warn this on the package as a temporary effect. I had this continual tingling, vibrating sensation in my teeth while I used the Whitestrips. It was annoying but did not hurt.

I had previously used Crest Whitestrips classic some years ago. The effects were similar, however you had to wear the strips for 15 minutes, twice a day, for 2 weeks. These new 3D Whitestrips are 2 hours, for 7 days. I found that wearing the strips for 2 hours felt like a long time, however, I did appreciate that the whole usage only took 7 days.

Overall, I am extremely happy with the results and think my white teeth look fantastic! I have recommended this to friends, and I will definitely be using this again.

I was lucky enough to received Crest 3D White Whitestrips Intensive Professional Effects as part of chick advisor product review club.

When I received them i was extreamly excited to start using them, as someone who enjoys their coffee, my teeth could use a little brightening. I put them on at night before bed time as i was watching some tv. They went on easy enough, and remained on, which was great. It didnt even feel (or taste - yuck) like I had anything on. They were easy enough to pull off after the 2 hours as well. The only downside was that after that first treatment my teeth were very sensitive. I knew that would be a possibility, but they hurt. The good thing was that the pain subsided within a day and I was able to continue with the strips. This product is definately something i would recommend and buy again. The results were amazing.
