Opalescence15% Gel Syringes Teeth Whitening Refill Kit - Low Sensivity (2 Packs / 4 Syringes) - Cool Mint - Carbamide Peroxide - Made in The USA by Ultradent Tooth Whitening 5195-2

Love this stuff. Used to have to buy it from my dentist but now can get it on Amazon for way cheaper. I was being charged $20 a tube so this is definitely the better option. Whitens really well but you do need a retainer which I had already molded at the dentist.

Bueno

I have had significant difficulty over the year finding a teeth whitening product that my teeth were not sensitive to. I would use strips or gel for a few hours and the pain in my teeth would be so painful I had to stop. I didn't think I could ever have white teeth, and I really wanted white teeth. So I saw this product online and decided to try the 15% strength, since my teeth are generally sensitive. I have plastic trays anyways since I did invisiline and so I tried it with my trays for a few hours. No sensitivity, no pain. I tried it again for a few hours and again, no sensitivity, no pain. I could see a slight whitening, even after a few hours of use. Then I decided to try it overnight (since that's what the instructions said) and again, no sensitivity, no pain. I have ordered this product 3 times (used almost 10 tubes), and my teeth are, without a doubt, white. The attached photo shows it to some degree, but in real life they are flat out white. So for about $100 I finally got the white teeth that I have always wanted. I have so much confidence now smiling and laughing, knowing that my teeth look fabulous. And I don't know what it is about this product versus others that I have used, but I am so thankful for the formulation. Great product!

Love this tooth whitening gel! Easy to use, gentle on gums, and tastes fresh. Noticeably whiter teeth after just a few uses. Highly recommend for a confident smile

Will buy again

I love that product. You can see a result after first day of using this

Muy bueno

Don't know if I got a bad batch or not, but this doesn't work as well as the Opalescence Go pre-loaded trays. They appear to be genuine, sealed product but neither has the mint flavor nor does it appear to work as well as the Go product.
