Opalescence Go 15- Prefilled Teeth Whitening Trays - 15% Hydrogen Peroxide - (10 Treatments) Made by Ultradent Products. Teeth Whitening Kit -Mint - 5194-1

I recently tried the Opalescence Go 15% Prefilled Teeth Whitening Trays, and I'm impressed with how easy they are to use! The prefilled trays make the whole process super convenient—no need to mess with gel or mold impressions. The mint flavor is refreshing, and I love that it’s gentle on my teeth while still delivering noticeable results. After just a few treatments, my teeth are definitely brighter, and I didn’t experience any sensitivity. If you’re looking for a hassle-free teeth whitening solution that works, this kit is a great choice!

Amazing results. You need to buy two kits. The first kit should be used on the top teeth only because people only see you top teeth when you smile. That's a total of 20 treatments. The second kit should be used for top and bottom together. That's 10 treatments. You'll thank me later!

The whitener works but i’m not sure the “one size fits all” approach is wise. Maybe if your teeth are well aligned, its easy to use , but i had trouble getting the lower to adhere to my teeth.

Literally THE best teeth whitening strips i use. I never try any other brand just because this one gets the job done after like 2-3 treatments without any sensitivity. my teeth stay white for a LONG TIME . very verg long lasting. its a little pricey but so worth the money. i would buy again again again….

Simply works. I've used dental strips and it just never feels as secure and easy to use. I'd say if you want pure white teeth you'd need 2 boxes but 1 is good if you're a heavy coffee drinker like me and want to touch up every once in awhile. Price and waste are the only downside but for something most people will only use once every 1-2 years I think it's really easy and convenient.

I am not sure these are working our not. I wanted to whiten my lower teeth as I am getting a bridge that I requested a shade lighter than my current color. I am able to use the uppers and lowers for my teeth so the box lasted me twice as long as a normal person. I don't know if it is because I am having a hard time applying them or just a bad batch. I bought another box to see if the shade gets better.They are very hard to apply. I dont know how many times that I have tried to remove the green tray just for the whitener to still be in it. I really have to press down hard everywhere and suck multiple times as well as wiggle it side to side to get the green tray to come off without the whitener. Very frustrating.My gums, also, are getting irritated from the clear tray that holds the whitener. It appears to be pushing down on my gums during the 15 minute or so time for application.As far as refrigeration, my dentist said that is only for if you are not going to use them for a while. If you are going to use them within a month or so, refrigeration is not necessary. I know there is a question as to 'well how long did they sit in my doctors office or at an Amazon facility' which I cannot answer.

I picked up my first box of Opalescence Go 15% from my dentist, who swore up and down these trays work just as well — if not better — than the in-office treatments. Naturally, I was intrigued. No appointment, no weird blue light, just pop in a tray and go? Count me in.So here’s how it went. You get ten prefilled trays, which is great. What the instructions don’t tell you is that the “just pop it in and the inner tray detaches on its own” thing? Yeah... that didn’t work for me. Not even once. I had to manually remove the insert (which actually holds the gel) from the outer tray and place that in my mouth. It’s not rocket science, but definitely not as plug-and-play as the directions make it sound.Once I figured out the manual detachment trick, they were easy to use. Wear them for 15 to 20 minutes, spit, rinse, and repeat the next day. I’ve gone through six of the ten so far. My teeth are definitely whiter, just not Hollywood blinding yet. That said, my wife used them twice and saw a dramatic difference—like, “You got your teeth done?” kind of difference.So I’m convinced: results vary, and your genes probably have more to do with whitening speed than the product itself. Also worth mentioning is that you can get custom trays made and buy the gel separately, which cuts the price in the long run. But you do have to lay out the upfront cost for custom molds.Bottom line: If you want a solid, dentist-recommended over-the-counter option, this is it. Just be ready to skip the outer tray, trust the goo, and manage your expectations unless you won the tooth lottery like my wife.
