Ow ow ow ow ow. Oh the PAIN! It's unbearable! It's like I sunk my teeth in freezing cold ice cream and just left them there for days straight. Someone make it stop!

"Your teeth may become sensitive when using Crest Whitestrips Supreme." Yeah. That's like saying, "Pulling your toenails out with pliers may cause minor discomfort." I seriously can't think about anything all day but this unceasing pain.

But this stuff does work amazingly well, and amazingly fast, and I'm going to continue using it. I just can't stand the thought of a few more weeks of this torture.

If you use these they will make your teeth whiter but it tastes horrible and once your done with the kit you have to buy another to keep them white and then another and another. Save some money go to the dentist and talk about your options. Ohh and stop drinking coffee soda and using tobacco or teeth whitening in general is just pointless... unless you get vaniers...hmmm?

The biggest problem with this product, other than the time it takes to lighten your teeth, is getting the strips to align to your teeth and not slip off. I actually had to use two whitestrips per row of teeth because the first one would invariably slide off or curl up in a ball at the ends.

The second problem is that what I was able to do using Touch of White Simple Kit 36% in three days still wasn't nearly as white as 10 days of these whitestrips. And if you look at the prices, you'll see why I was so happy to have found Touch of White after spending so much money on this product. So save your hard-earned cash and give TOW a try. And for sensitive teeth, be sure to pick up some Sensodyne! I use it for cold-water problems, so I didn't have any problems with this product.

I purchased this product for my son. He was looking for a tooth whitener but I didn't want to spend a fortune for a dentist to do this so I thought I'd try this product after seeing a few reviews. I'm amazed at how white his teeth are! Even the fluoride marks on his two front teeth are gone--bright, white but not fake looking. I highly recommend this product and will purchase it again!

I decided to buy this product after a popup showed up on my screen one day for "Celebrity Sexy Teeth" which completely bashed Crest WhiteStrips Supreme. As I began researching it, I realized that there is no research to suggest that this other supposed whitener is any good and that individuals are even unsure of the ingredients coupled with the poor reviews it received.

Anywho, onto this GEM! I bought two boxes thinking that my teeth were so yellow that I would need two boxes to get the desired results. How wrong was I! After using the strips for less than a week, I already saw results.

I experienced minimal sensitivity, but I believe my teeth were more sensitive if I brushed them before using the strips which Crest does warn against. As such, I never had to skip a few days and my teeth are getting naturally whiter and I continue to receive compliments.

The box is not completely done yet; but my teeth are already several shades whiter!

I could not more highly recommend this product as I feel the results are equivalent to what one would get by paying hundreds of dollars for an hour in the dentist's chair; the results are just spread over a longer period. I feel that whitening over time, progressively, will cause people to wonder "Wow, there's something different about you but I can't put my finger on it!" Which I would much more prefer than "Oh wow, now your teeth are white!"
