Opalescence Opal Go - Prefilled Teeth Whitening Trays - Gentle - (7 Treatments) - Hydrogen Peroxide - Cool Mint - Made by Ultradent. Op-Tr-Gent-5526-1

I absolutely love these whitening strips! I initially got them directly from my dentist's office on their recommendation, and they have truly been the best I've ever tried. My teeth have never looked brighter. However, I do want to give a heads up if you have sensitive teeth, these will likely cause some discomfort or pain. It's a powerful formula, so be prepared for that sensation. Despite the sensitivity, the results are worth it for me!

I’m halfway through the 7-day treatment and already really happy with the results. The trays are super easy to use and only take 30 minutes a day. I like the light minty taste, and best of all, I haven’t experienced any tooth sensitivity. Looking forward to seeing the final result — so far, so good!

Love these whitening trays! I have very sensitive teeth so I just dont leave them on as long as recommended, but still get great results!

Great product - works as stated, excellent results when instructions are followed.

Didnt work as much as I hoped. Didn't really notice that much of a difference.

Not for sensitive gums and teeth. Used twice and threw them away. Painful mouth for several days. Could not get them to stay in place.

I was so excited to try these as I had read tons of good reviews but they didn’t work as I expected. I used according to the package instructions but didn’t notice any whitening results. I had lots of sensitivity with these as well. On the positive side these trays were very easy to use and it seemed like the product stayed on very good compared to others.

My favorite teeth whitening product. Brand was recommended by my dental hygienist and Amazon had the cheapest price I could find. Does not whiten as bright as other products but seeing as it’s for sensitive teeth it does a gentle whitening. Did not make my teeth hurt like other whitening strips have.
