The syringe format makes it easy to apply evenly into trays without wasting product, and the consistency is just right—not too runny. What stood out most is that it actually works without causing any sensitivity. I noticed a gradual whitening after a few uses, and my teeth looked noticeably brighter without that sharp discomfort some stronger products can cause. The mint flavor is mild and not overpowering, which helps during wear time. Also, each syringe lasts longer than expected since you don’t need much per application. Overall, a reliable and effective option if you want professional-level whitening at home with lower sensitivity. Review: This really works!!! - 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. ## Features - PROFESSIONAL LEVEL TEETH WHITENING: Opal by Opalescence - A teeth Whitening Experience in the comfort of your home, with over 30 years of expertise, 50+ Teeth Whitening Awards, and 100 million smiles brightened. - DELUXE OPAL BY OPALESCENCE LINE: NO LED Light Needed or Recommended.

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 ### ⭐⭐⭐⭐⭐ Effective whitening with minimal sensitivity *by B***S on May 4, 2026* I’ve used a few whitening products before, and this Opalescence 15% gel has been one of the better ones.

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! ## Frequently Bought Together - Opalescence 15% 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 - Opalescence 20% Teeth Whitening Refill Kit (2 Packs / 4 Syringes) Carbamide Peroxide.
