OpalescenceGO 15% (10 Treatments) Original Prefilled Teeth Whitening Trays w/Travel Whitening Toothpaste 1.0 Oz. Hydrogen Peroxide - Cool Mint - Made by Ultradent.

This is my go to teeth whitening kit. You can see a difference in one sitting.

This stuff keeps my teeth so white, I love it. Easy to use and affordable.

stopped using due to gum irritation

You control your whiteness!

As my headline stated it worked great, When I wanted to re-order; the price had gone up 26%. It is even higher now. So I think again it works great, but has gone out of my "Value" for price now asked for. I did then go to there toothpaste, but it does not seem to do much at all So for the price of this toothpaste, I think I will try other whitening tooth paste.

I ordered two of these. I ended up using both of them, a total 20 trays. I tried to follow the instructions but found that if I applied the trays using the green outer tray, removing it also removed the inner white tray. Therefore, I removed the outer tray before applying the inner tray. I doubt this had any impact on the end result. After using all 20 trays, I had no discernible whitening of my teeth.Considering the cost of the product, one would be better off using that money toward a professional whitening treatment

I researched a lot to figure out what to choose for whitening, and went with opalescence because that's what is sold in my dentist's office. This is easy to use and I saw a difference right away.I only needed three treatments, so I have a bunch for touch-ups from time to time, or for my husband to use.I did experience sensitivity and redness in my gums, and used sensodyne toothpaste and Aleve to mitigate it the discomfort. Works way better for me than Crest white strips. I only used for 20 mins once a day. Very easy!

I have 3 more trays to go, but really haven’t seen a big difference yet. I use the trays at night, 1/2 hour.I’ll try adding more time to see if there is any lightening. I was hoping t the cost, I would see more.
