I have used other Crest Whitestrips in the past to no avail. I got these from Chick Advisor to try and was a bit skeptical at first. I took a before and after picture from the first day and was pleasantly surprised that these actually make a difference after one day! I will say they do make my teeth a bit sensitive, especially to hot food, which I've never experienced before. I would say I have very low sensitivity to cold food normally and these have not made any difference in that.

My one concern is the fact that these DO NOT stay in place for 2 hours! After half an hour they seem to get really loose and i have to constantly push them back down on my lower teeth. The fact they have to be on for 2 hours can be a bit of a nuisance but it is definitely worth it so far! I drink coffee/tea/soda on a regular basis and needed these. Other than that I'm super impressed and I will post before/after pictures after the 7 days.

I was so excited to be chosen to review the product and am so happy with the results. After 20 years as a smoker this was exactly what I needed to whiten my teeth and will definitely buy again.

thanks so much Crest

I was really excited to test out this product. Overall, I enjoyed it and its results. As I DO indeed have whiter teeth.

PROS:
You get results
Not as expensive as going to the dentist
Easy to apply/remove
Does not take long

CONS:
Left little white spots on my teeth for quite awhile.
The strips are annoying in your mouth

I personally did not have any pain. It was a quick easy way for whitening.

I have used the Crest whitestrips and i must say i was very impressed with the results. My teeth look wither than they ever been! I even receive several compliments from friends about how white they look...yeah for me! Putting the strip wasnt that fun though, the process was a little boring to do but it was well worth it.

Thank you ChickAdvisor for selecting me to review this great product! I was so excited when I first received the Crest 3D White Whitestrips Box, that I rushed right into my bathroom and put the strips on my teeth. I wasnt sure what to expect, since my teeth are a little sensitive.
The directions said to leave the Whitestrips on for 2 hours, but by the 60 minute mark, my teeth started to feel a little bit of pain, so I removed the Whitestrips. I must say though, I was impressed with the results after the very first try! My husband even noticed when he got home, that my teeth were a tad whiter:)
I followed the directions throughout the 7 day trial period, but could only keep the whitestrips on for 60 minutes due to the sensitivity in my teeth. Even still, I was VERY impressed at the results by the end of the 7 Days! My teeth whitened like 3 shades brighter, which was noticeably huge! I had friends and family comment on how white and how bright my smile was~ they all asked me where I went to get my teeth done;) When I told them I had used Crest 3D Whitestrips they were shocked, yet impressed that the product whitened my teeth just as well as a treatment at the Dentist's. Since my experience with Crest 3D White Whitestrips, 4 of my friends, and 5 of my family members have gone out and bought this product too!
Thank you again ChickAdvisor for giving me the chance to review Crest 3D White Whitestrips Intensive Professional Effects. I am very happy with my results and I will DEFINITELY be buying this product again! This product may be a little pricey, but its totally worth it! :)

Got this from Chickadvisor to test out. I must say these really did the job perfectly!!! My teeth are at least 4 shades whiter!! They were a bit tingly after I had them on, but overall, a great product & investment indeed!
Thanks ChickAdvisor!

I received this product as part of the Product Review Club for Chick Advisor.

I was excited to try these out because the last time I used white strips was about 5 years ago and I found the product messy and annoying to use.

These, however, were easy to apply and thanks to the advanced seal. stayed on really well without any funky taste in my mouth.

HOWEVER, I only made it one day with these things, as after using them for only 30 minutes on day 1, I woke up to excrutiating pain (worse than when I had braces) and I couldn't stand it. It lasted a full 8 hours -- I couldn't make myself put them on again.

That being said, I read through the instructions, and because these were the highest level of intensity, they do warn you they will most likely cause sensitivity.

I wish I could have handled these for longer, but I am a bit of baby when it comes to teeth pain (I can't stand any kind of teeth related pain)...

For tough chicks who don't experience sensitivity, these may be for you. I didn't think I had sensitive teeth, but maybe I do. But if you are concerned about having painful teeth and gums, then please don't use. its not worth it for a brighter smile.

Thanks to ChickAdvisor I was chosen to try Crest 3D Whitestrips Intensive Professional Effects for FREE :) Thanks a bunch!!

So the day I got the box I went to the bathroom read the pamphlet and I too didn't know what was top and which was for the bottom. I think maybe a T or a B would have helped, but I figured it out.
The taste was soooooo gross, hard to get passed...maybe add a mint flavor to help cut back on the chemical taste.
After wearing for 2 hrs the first day I noticed that my bottom front teeth were really sensative with shooting pain from the top of the tooth to the gum line. The second day wasn't as bad with the pain but the taste was still nasty and made me gag quite a bit lol
I did notice a difference in the brightness of my teeth especially after the 5th day.
I would try again if they maybe changed the taste...for me it was really hard to get passed :(
I will recommend to friends who don't want to spend a lot of money and get almost the same whiteness as the dentist.

Thank you so much Chick-Advisor for selecting me to review these Crest 3D White Whitestrips Intensive Professional Effects.

These really works! I had a hard time the first couple days to put them on but I got it. My first day was excruciating my teeth were so sensitive. But it was less painful as the days rolled on.

The results were great! My teeth are noticeably whiter. I'm so happy and satisfied with this product! I would definitely use it again and recommend it.

I received this product from the product review club and used it last week.

I LOVE the results, I will use it again once it is needed. Even my friends and family noticed the results. My teeth were not heavily stained, but definitely needed a lift. I found the product easy to use, the instructions were clear, and the strips stayed on very well for 2 hrs at a time. I was able to have water while wearing the strips also.

The first time I used this product I experienced majorly sensitive teeth after about 8 hours. I don't normally have sensitive teeth, nor do products usually cause it. To relieve this sensitivity I used a toothpaste designed for extreme sensitivity and it helped. I used that same toothpaste the whole week I used the strips and it made it bearable. The sensitivity lasted until 2 days after I used the last set of strips, however, it would not prevent me from using this product again as the pain didn't last.

I would recommend a "Pro Relief sensitivity" toothpaste to go along with your use. I wonder if Crest has considered included a paste or rinse for sensitivity in the package, because it seems that even if you aren't prone to sensitivity it does happen.
