I hate how these burn and recede the gum line** A: You should only use about 1/3rd of the syringe per tray. If it is squishing up and out you are using too much. **Q: Do you need to use a teeth remineral gel after use? If so , how does one do that procedure?** A: I first used this stuff when my dentist gave it to me many years ago and now here it is on Amazon. I have never used a remineral gel. **Q: what is the expiration (or use by) date on the item i will receive?** A: I bought them in July/August 2019: My expiration date was 2021.03.31. **Q: Is this percentage(15%) to strong for sensitive teeth.?** A: If your teeth are sensitive use Sensodyne toothpaste as your regular routine for a couple weeks before using 15% and that should help. That’s what we give our patients. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very pleased! *by on Reviewed in the United States July 26, 2026* 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! ### ⭐⭐⭐⭐⭐ Awesome teeth whitener *by on Reviewed in the United States July 6, 2025* 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. ### ⭐⭐⭐⭐⭐ Whitening without sensitivity *by on Reviewed in the United States November 21, 2024* 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.
