GO Teeth Whitening Prefilled Trays with Toothpaste Bundle (10 Trearments) 15% Hydrogen Peroxide Gel Plus Opalescence Whitening Toothpaste 4.7 Onz - Original Mint Flavor 5194-5166

After using the full box my teeth are a few shades whiter. Not stark white by any means, but it noticeably removed years of coffee, Diet Pepsi and the occasional glass of red wine stains. My husband used a different brand and he will try these now that I finished and had great results. My teeth were not sensitive with these. The toothpaste is also really good.

Works as advertised, however, I find the most significant thing about this product is its ease of use and clear instructions. It resulted in the significant whitening of my teeth.

I tried the Opalescence Go whitening trays and I’m very happy with the results. They’re super easy to use—just put them on and let them work, no mess or complicated steps. After just a few uses, I noticed my teeth looked noticeably whiter and brighter. The trays are comfortable to wear and don’t slip around, which makes the process simple and convenient. I was worried about sensitivity, but I had almost none compared to other whitening products I’ve tried. The mint flavor is also a nice touch, leaving my mouth feeling fresh. If you’re looking for a professional-level whitening treatment you can do at home, this is definitely worth it.

They really work! They are a bit pricy. But that last order I got I had two of the upper trays that were empty. There was no inner liner so I lost two applications from that whole box . Weird… but that had never happened before.

My sister and her husband own a dental practice- this is the only at-home teeth whitening kit they recommend. Works so well!

This stuff is awesome. I’ll admit I saw it at my dentist’s office and then immediately looked it up on Amazon. I’ve tried “opalescence” 30% strength in the syringe from Amazon before, but I think it was either a fake or I didn’t use it right. These trays are idiot proof and you'll have a brighter smile after just a session. I should’ve taken before and afrer photos just to show my 4 days of progress, but you’ll just have to believe me. One thing I’ll note is that I misread the instructions and thought the time was 20 min per tray. This definitely burned my gums some and turned them white, but they recovered quickly and I didn’t have to stop my sessions. I may even keep pushing it to twenty now that my gums seem used to it and I’m seeing such dramatic results. Otherwise, you should stick to the ten min per tray per the manufacturer’s directions.

I've heard they work well, not so much for me. The trays don't always easily release the portion that stays behind.

These work as advertised.
