I love these whitestrips. The work much better than any competitor brands and I did not have any sesitivety issues with these ones.

I was really wowed by these whitestrips! I have used the classic 14-day version in the past but it had been a while since my last whitening and needed something that would brighten my teeth a little more quickly.

The seal on these strips was incredible. I actually had to tug for a while before they came off after the treatment time! Unlike my previous experience with strip whiteners, the fact that they stayed in place led to less product getting into my mouth and producing extra saliva. I also think the staying power led to more uniform whitening. When strips slip and slide, I usually get patchier results in the early days. All of these issues were big reasons why I don't whiten as often as I'd otherwise like.

Another reason I don't whiten very often is because I have sensitive teeth. I knew all along that these strips are not specifically designed for sensitive teeth, but I needed to whiten and I received this box of product for free so I decided to pace myself and see how it would go.

So far I have only used the strips for one treatment, but that's all that was needed for me to already see noticeable results. I plan to do 2 or 3 more treatments over the coming weeks, but I think I might save the other strips for a later time. I had some discomfort for a day or two after the treatment but it was manageable. I took one regular strength Tylenol on the first day and that really helped.

I would recommend this product for the quick results, the highly effective seal, and the short treatment period (normally it's a 7-day treatment). Some sensitivity is normal, so pace yourself if needed, use Sensodyne or other sensitivity toothpaste, and make sure your teeth and gums are healthy before starting. I'm sold!

love it , i find your teeth look much whiter and feel more clean with the product, a bit pricey but worth it , does a good job

I received this product for free as a part of the Chickadvisor product review club.

I have used whitening products before with no avail, even went as far as buying a professional liquid one online. I didn't expect a lot from the Crest 3D Whitestrips Intensive Professional Effects, but I was pleasantly surprised. Within 7 days the product had made a big difference to my smile. I feel better about it already. I will certainly be referring it to my friends, and I will certainly be purchasing it again.

It was extremely easy to use, and stayed on really well. You can even drink water with them on and they are really comfortable. The only downside that I found with working 5 days a week and going to university the other two was finding 2 hours everyday to put them on.

Thank you again ChickAdvisor, for showing me another great product.

I received Crest 3D White Whitestrips as part of the Product Review Club! Based on my previous experience with whitening products, I didn't expect much out of Crest 3D Whitestrips. I was pleasantly surprised that these Whitestrips actually do perform as advertised!

First off, they are easy to apply and stay on for the recommended 2 hours. My results were most apparent in the first few applications. I experienced mild pain after my first application which was different than what I would call sensitivity. A pain in which it was hard to drink the extremes of hot or cold fluids - which personally, has never happened before. Based on this pain, I followed the instructions thereafter and increased the gaps between my usage to at least 2 days. Overall, the result using the Whitestrips for 7 days are my teeth are exponentially white - a shade that they've never been before! And the best part is, that it is a prolonged effect that has been lasting a couple weeks after usage as well.

This is a product I will use again in the future. If you're looking for increasingly whiter teeth and willing to pay for a pricier product, I definitely recommend Crest Whitestrips!! Happy teeth whitening to all!

Not sure why my other review didnt post but will repost :)

I got the Crest 3D White Whitestrips Intensive Professional Effects to try and review. They are very simple to use and surprisingly stayed in place for the duration they were on my teeth. Once I took them off I noticed a slight difference in colour just after one application. After completing another my teeth were significantly whiter and the only downside I experienced was a slight bit of tooth sensitivity for 2 days but it was nothing painful or overwhelming compared to other methods of teeth whitening.

I give this 4 thumbs up and suggest anyone trying to get a whiter smile for any reason to give them a try they are a great value and often P&G;puts out coupons for these - I currently have a $7.00 off coupon from them and look forward to finding it on sale and getting my next box on a discount :P

The Crest 3D white strips did do what they claimed, and were easy to use. The length of time that you did have to keep it on, was a bit bothersome. The strips did stay in place very well, and I received slightly above average whitening.

I may consider buying it again if a special occasion was coming up, and the price went down, and I would recommend it to a friend if they were in need of a product to try.

Please note I was fortunate to receive this product free to test.

I found the Crest Whitestrips very easy to put on and that they stayed in place for the required time.

As for effectiveness, I saw a slight whitening, but not much. Luckily my teeth did not feel sensitive as other advisors had noted.

I do agree that the adhesive, though efficacious, was a lot to get off after the treatment.

Although the Whitestrips did a decent job for the price (in comparison to a salon on dentist's treatment), I did not enjoy the length that I had to wear them for the whitening achieved.

Crest 3D Whitestrips Intensive Professional Effects worked well & did what it claimed. It did whiten my teeth, however, i used it over 14 days. My teeth are a couple of shades whiter, and i did experience some sensitivity (which is normal). They adhered well and peeled off rather easily. it's great that they stay put & don't move around like some other products i have tried in the past.

2 hours is a long time to keep them on, but if you are diligent & follow the instructions, the whitening is effective & noticible.

i would recommend them to others, but the price is a little high ($69.99 retail) for regular maintenance after initial use.

i thank chickadvisor for providing me with the opportunity to test them! my smile thanks you too! :D

I was very excited to try this product, however only recieved average whitening. My teeth were a bit whiter ( not a huge difference though ) and felt very clean. I did experience tooth sensitivity to the product so used it every second day instead of everyday ( maybe that is why the effect was not as good ). I am very busy and honestly finding 2 hrs to sit with teeth whitening strips on a day for a week ( or in my case 14 days) was very hard, I know people say you can do other things with them on but it was still hard haha! They did stay in place really well which surprised me I was expecting them to move around and slide off, but I almost had to peel them off :) Overall I think these are a good product even though they did not whiten my teeth as much as I was hopeing I will likely try them again in the future.
