Opalescence PF 15% Teeth Whitening 8pk MINT (Latest Product)

I left this on over night and I definitely noticed a BIG difference in color. My teeth are definitely whiter after using this only one time. This stuff does work. But be careful with it. My teeth were pretty sensitive for 2 days. The 1st day after, it was fairly painful. And I noticed that my gums were irritated in a few places. The day after that, the sensitivity was still there, but to a lesser degree. Definitely not for daily use. More for a deep whitening. I wouldn't recommend over night use. I'd say an hour or two at a time would suffice. Overall, I am happy with the job that this stuff does. You need trays for this item. Something that you can get from your dentist.

The Opalescence works well. I have used it the last time about 2 years ago. Now with the "update" I used only 1 pk of theeth whitening and everything was white again. Don't put to much!!

Opalescence PF 15% Teeth Whitening 8pk of Mint flavor syringes (GUARANTEED FRESH) My dentist told me about buying this product on-line otherwise I would be too skeptical. Still it bothered me because I was worried about shelf life. My product had the shelf life scratched off - which is not good. 3 Starts for that. Nonetheless, it really worked and my teeth clearly whitened up. 5 Stars for that. Would only use this occasionally - hope it really is from the company branded on it and not some China knockoff with cow urine, toxic lye or some other awful chemical in it! 1 Star for that. This would be a 5 Star rating if not for the scratched off shelf life which ratcheted up my concerns about origin or quality.

meets expectations

I have bought this product in the past from the dentist and it worked great. The same product from this supplier had little (if any) postitive results. I think that it is expired. Suspiciously, it did not come in the normal box that I am used to which contains the expiration label on it. I will not buy from this supplier again and recommend that you go elsewhere.

Very good product and cheaper than anywhere else I've looked. Would recommend to anybody.

The product does exactly what it advertises. You need to have your own trays for your teeth. I had mine fitted at the dentist. The dentist whitened my teeth and I use this product as maintenance. It works much better than Crest Whitening Strips and the results last longer. I use Brite Smile toothpaste. Although pricy, I also found that it keeps my teeth whiter between applications of the Opalescence.

I wanted 15% and I got 20% that is ok with me thanks
