Opalescence 15% Carbamide Peroxide Teeth Whitening Gel Syringes - 5195-2 | (4 Units) Refills for Trays. Low-Sensitivity Formula, Mint, Developed by Dentist. Made in USA by Ultradent.

My husband orders these frequently. Happy with the product and results. Good price.

Had a healthy dose of skepticism about these working, but I was pleased with the results. My teeth can be very sensitive with teeth whitening, but I tolerated this well. I used old molds made by my doctor and followed instructions to use a rice-sized amount per tooth. The suggestion to wear for 4-6 hours seemed like a lot, but my teeth had no issues after hour 1, so I continued for 5. The end results were notable and teeth were white again. Very happy!

I work at a dental office and we sell this brand, however its cheaper to buy from Amazon. They have different percentage. Start a lower dose to see if you get sensitivity. This dose works well starting out it starts lifting stains which is what lightens your teeth to a brighter shade. Its easy to use.

I have been liking this product but it is definitely not a quick fix. I have been using for a week now and finally am noticing a difference. I do appreciate that it is dentist recommended and better for enamel, but be prepared to be patient! I am experiencing slight sensitivity but overall it feels very gentle!

always works on my teeth and get many compliments and questions on what i use!

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!

I’m very impressed! I honestly didn’t expect this to work, but it definitely whitened my teeth. I noticed a visible change after using just one strip. I’m not a fan of the "blindingly white" look, so I stopped early, but it was well worth the $32. My dentist quoted me over $300 for a professional treatment, so I used these strips along with my orthodontic retainers to get the job done for a fraction of the price. Now I still have another 3 stripes to repeat the process when needed.

I’m not sure about this whitening gel. I’ve ordered it a few times, and this package…the gel was extremely thick and hard to put into my whitening trays. The expiration date is good. The gel just seems different to me.

Really good, does its job, will definitely purchase again

جربتها اختي بس حسستها لانها تطول فيها سو انتبهوا لا تطولون فيها

Very good product

شوفوا استخدامها الصحيح ، انا بالبدايه كثرت وتحسست اسناني

I have used this before and it’s a great product. My teeth are sensitive so I go for the lower percentage.
