I recieved the Crest® 3D White Whitestrips Intensive Professional Effects, free to test as part of the chick advisor product review club. I was extremely excited to try this product upon recieving it. The first time i used it I noticed a major difference in my teeth colour. Although the bottom strip, did not stay on as well as I thought it would. I did experience a bit of tooth sensitivity, but mostly on my bottom teeth. After the fifth day of using this product, I am absolutly floored! My teeth are super white and feel amazingly clean. I will definatly be buying this product again, and will definatly be recommending it to my family and friends.

I got to review this product through ChickAdvisor's product review club (:

When i first received this in the mail, I was so excited to test it out, and tried it first that very day. Even after just one use, I could notice that my teeth were definitely whiter than before. Not extremely whiter, but definitely whiter.

Now, almost having used up the entire box, my friends and family have all been noticing my whiter teeth. My moderately yellow teeth have been changed to a very pale/light yellow. Many people have been complimenting my teeth lately, which is definitely a great sign.

The only downside to this product is that it makes your teeth a little more sensitive than usual, especially when you're outside and the wind starts to pick up. Nothing that a little sensodine cant fix, but other than that there are truly no down-sides to this product! I definitely would recommend this product to anyone who wishes to whiten their teeth in 7 days. For the professional quality and results this product gives, the price tag is definitely worth it!

Up front, I will say this product gave me amazing results. My teeth are absolutely glowing white and I love it. So, it you want super white teeth without the dentist cost, this is definitely an option.

HOWEVER, it didn't come without a cost.
First off, if you have sensitive gums, this product may not be for you. Personally, I do and this product caused them to become very inflamed.

I also found this product made my bottom teeth quite sensitive. Not super painful, but definitely flinched with super cold water a couple of times.

Using the product was pretty simple, although I did have trouble keeping them in place 2 of the days. Being a mouth-breather, I tend to create more saliva than most and I think this affected the 'staying power' of the seal. It was still better than other versions of this product I've used in the past (sometimes those didn't stay on for 20mins) but most days, these did last the full 2 hours.

Which is another somewhat tough thing. Keeping them on for 2 hours felt like a bit much sometimes and I removed them on occasion before the time was up, as they were starting to 'leak' a bit.

All in all though, as I said, they're definitely worth it if you really want super white teeth, but be warned there are certainly some side effects.

5 days ago I have received Crest 3D White Whitestrips Intensive Professional Efects
Firstly, I would like to mention that I have always dreamed about trying some kind of whitening, but the the idea of going to the dentist`s office was not really reasonable for me. Crest suggests an alternative 500$ at your doctor`s clinic. I am satisfied wirh the price.
Secondly, the quality is amazing. Now I have a great smile. It took me only 5 DAYS! Only 5! I am looking for day 7 to look at the final result.
Finally, there is the Advanced Seal Technology. It insures that the streep will not slip during those 2 hours. For me as a customer it matters a lot since I am slightly scared for my gums. They are not at all sensitive, but you never know what may happen.
To sum everything up, I am 100% happy with the whitestrips.
