Opalescence Go - Prefilled Teeth Whitening Trays - Original 15% - (4 Treatments) - Hydrogen Peroxide with PF - Cool Mint - Made by Ultradent. 4648-1

These work extremely well! My teeth are definitely brighter! Only recommendation is to brush your teeth with a toothpaste that’s for sensitivity. Most teeth whiteners do cause tooth sensitivity and these are no exception to that but they work as expected!

One off the best teeth whitening out there! So easy to use and makes your teeth sparkle. I am a teeth whitener girly. This is by far one off the best.

Great product

this product is good and I did notice some difference but not a whole lot. as much as this product is good I’ll stick to using whitening strips.

This did not work. I wasted my hard earned $46 on this product. Used all 4 pairs of trays and saw 0 results. Absolutely 0 results. I previously used the crest whitening strip and got great results. I will go back to the crest strips. This product is absolute garbage.

I had tried Crest strips and other methods to whiten my teeth getting mediocre results. My sister-in-law had these, recommended by her dentist, so I got some to try. I was impressed the first time I used them. I left them on 45 minutes the first time, 30 minutes after that. Using once a month. Expensive but worth the money to get better than mediocre results.

Product does work only gave 3 stars because 2 trays that were packaged were completely empty maybe a mistake at factory but was very disappointed.

People constantly ask me how my teeth are so white. These little babies is how.
