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.

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!

LOVE this item! I got the exact same brand from my dentist's office but at a much higher price with them. I found this same brand on Amazon (with different levels of options) at a lower price and knew this is what I needed to get. Comes in 2 packs of 2 syringes. I generally use this every other night (I don't want my teeth to get too sensitive) and the tubes last me a good while. I'd say I can get at least 3 days out of 1 syringe (using on both top and bottom, all teeth). Flavor is decent. Stays put all night in my retainers and actually whitens! I don't have a shade test, but they are many shades whiter now. I am very pleased with this product.

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!

Easy to use and definitely does not irritate gums (mine are sensitive). My teeth were not too bad, but I wanted them to be whiter. I used two sets of this product and achieved a whiter appearance without any side effects. If you want to improve your appearance but not become bright white, this product is good.

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

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.

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

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.
