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

I used to get this brand from my dentist so I trust the quality. Now that I have moved out of state, it’s nice to be able to access these trays online. I keep them in the fridge for freshness as it was suggested by my dentist. They are pricey but it’s a nice alternative to professional whitening.

These are quick to lift stains! I have noticed whiter teeth after 2 treatments. They are also pleasant on my sensitive teeth. Recommend to anyone with sensitive teeth who wants a brighter smile!

I have been using these for years and always get a lot of compliments on the whiteness of my teeth

They work great but sometimes the inside tray won't separate from the outside and it becomes unusable. Inside tray should stay on your teeth and outside tray comes away to be trashed. Inside tray sometimes fails to stick to teeth. Yes, I'm following the directions :-)

My teeth are very white love this product

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 haven't used the product yet (and yes, I hate it when people do this), but wanted to give everyone a heads up that it needs to be refrigerated. After a week of it sitting on my counter, I finally opened the box and read the directions, and buried at the bottom was a little note that these trays need to be stored in the fridge. This not written on the outside of the box or anywhere else on the packaging. This is no indication that the were refrigerated in the warehouse, either.Also, the timing on the instructions appears to have been written wrong. It says: 10%, 30-60 min. 15%, 15-20 min.

Great product
