Low-Sensitivity Formula, Mint, Developed by Dentist. Made in USA by Ultradent. : Health & Household Review: Very pleased! - 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! Review: Happy - My husband orders these frequently. Happy with the product and results. Good price. ## 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 ### ⭐⭐⭐⭐⭐ Very pleased! *by A***A on July 26, 2026* Had a healthy dose of skepticism about these working, but I was pleased with the results.
