I wanted To try these so I bought some. I put one treatment on and everything seemed to be fine. That is until I felt the most in forgettable pain in my teeth after using that night. I felt like I had a toothache that kept me up all night long. Needless to say I won't make that mistake again.

May have worked for other people but after I used it I didn't see the difference at all. It actually made my teeth sensitive for a couple days and my gums were hurting a little bit.

I have been using regular whitening strips but recently i decided to try this ones to save some time but it was not worth it. I do have sensitive teeth but after thise strips my teeth were so sore even few hours after. So no more i will be back to my regular white strips. Moneywise it was expensive too.

Used my SDM Optimum points to buy these when they were on sale.

I followed directions to the letter. After about 5 minutes, every tooth in my head started hurting. I kept them on as long as recommended, and needed Advil. The pain subsided after about half an hour.
In terms of effectiveness they did whiten my teeth, but on the side teeth, actually left whiter dots, as though the whitening agent did not spread onto the entire tooth. After a few brushing so, it evened out.
I gave them to my sons...both have tried them. One experienced the same sensitivity as me, but had great results. The other experi need no pain, and was pleased with the results.

They whiten great but they make my teeth very sensitive, so I have to use them sparingly because of the sensitivity.

I wasn't impressed with this product. I found it was difficult to get off my teeth because it was so sticky. It was actually quite painful trying to get the strip off. After all that pain it didn't really whiten my teeth. I will just stick with the toothpaste.

Very expensive, but whitens well. It does really increase my tooth sensitivity though

I tried this and it is not the best for me, I don't like things in my mouth and definitely not for longer than a couple of minutes. I am sure some people can handle it, but it is not for me

I was disappointed with these 2 hour 7 day strips I didn't notice an amazing result with them. I got more compliments on the 30 day level 3 strips than I did with these... I bought them when I was finished with Invisalign and it just wasn't as awesome as I hoped.

I did not have sensitivity issues while wearing them, I noticed my teeth were a wee bit sensitive the next day. My boyfriend tried them and said they immediately hurt his teeth after 5 minutes.

While I have had success with the other strips, perhaps this one just didn't work well with my teeth? Next time I will just purchase the 30 day kit instead.

I would recommend this kit to someone looking to whiten their teeth fast, I just didn't get the results I was hoping to get from "intensive professional" whitening strips.

This product left white spots on my teeth and made my teeth super sensitive and very painful. Not a very good experience at all.
