desertcart.com: Opalescence 20% Teeth Whitening Gel Refill Syringes, with PF (8ct) 5401-4 | 20% Carbamide Peroxide with Potassium Fluoride Melon Whitening Gel for Custom Trays. Low-Sensitivity Formula. Made in the USA : Health & Household

Review: Best Whitening Product - The same product you get at the dental office for half the cost, I saw results after the first use and had little to no sensitivity. I read to just put a dot on each tooth in your retainer/tray, and this has saved so much product. Will be purchasing again!
Review: Did what I had hoped for - I had professional teeth whitening done at my denti$t's office and the result was meh. I decided to try it at home using these syringes of bleach and my LED face mask for blue light. With the initial use, I had a better result than the one I had when the dentist bleached my teeth. My teeth are noticeably whiter. I went conservative and bought the 20% strength and left it on for 14 minutes with the blue light on medium---I'll use that as a baseline. No gum irritation & teeth aren't sensitive, so I will cautiously increase the times by one minute and the level of blue light. * Good tip is to use a generous amount of lip balm before you "Light up".
