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

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!

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".

This is the same product that my dentist charges 80 dollars for. The product works great to whiten teeth. Great product

effective

Excellent!

horrible. This was so thick and dried up wouldn't even come out of of the tube. Couln't even use. Waste of money

I tried the white strips and while they were good, they were not great. I decided to fork over the money and get the custom whitening trays from my dentist. The kit came with the Opalescence 20% Melon. My dentist said to purchase from her would be costly, but I should try Amazon. I am in the process of getting some old crowns replaced and wanted to whiten my teeth prior to getting the crowns so that the color would match as closely as possible. I am only in the second week, but my smile seems brighter. The price was definitely a plus!

I have ordered these before, but originally got them from the dentist. These are much cheaper and do the same for me.
