Teeth Whitening Gel for Trays – Pro Strength 44% Carbamide Peroxide, 5 Syringes (50 Uses) + 2 Trays, Enamel Safe Teeth Whitener, Removes Coffee, Wine & Tobacco Stains, at-Home Pro Whitening Kit

I have been using the 22% carbamide peroxide for many years to keep coffee and food stains from yellowing my teeth. I did not know the 44% was available and was even more surprised to find out that I do not have to get this from my dentist. I was grossly overpaying my dentist for this product. This kit says it has enough product for 50 uses as it does not take much. I used this the day I received it and for this strength it only takes about 10 minutes. I did notice some slight sensitivity at first but it went away quickly. This product is not intended to be left on your teeth for long periods of time. I had a few coffee stains on the edges of some of my teeth and on the top of some of my molars and this took off the stains I saw in that 10 minutes. This is a great product and very affordable. I only use about 1x a month to keep stains away as my teeth are already pretty white and this works perfect.

This works very well comes with 2 cups for your teeth that you warm up and shape to your teeth , great instructions. It is a stronger whiter for sure. Be careful..

used this whitening gel with trays and it does what it’s supposed to do — my teeth looked noticeably brighter after a few uses. The gel is easy to apply, and a little goes a long way, so you don’t have to load up the tray to get results. If you have sensitive teeth, start with shorter sessions and space it out, because using too much too often can make you sor

This whitening gel HURTS. It makes your teeth SUPER sensitive. But it does do a decent job whitening your teeth so it’s a trade off. The other thing I didn’t like is the tip you have to put on the pen keeps popping off. It’s annoying.

I’ve tried a few whitening kits before, but this one is by far the most effective and easy to use. The trays were simple to mold to my teeth, and once they fit, the gel applied evenly without any mess. I noticed a visible difference within the first week — my teeth looked several shades brighter, especially after years of coffee and tea stains. What I like most is that it didn’t make my teeth super sensitive like other products have. The formula feels gentle but powerful, and I’ve had no gum irritation at all. I also appreciate that it’s vegan, cruelty-free, and BPA-free — nice to know I’m not putting harsh chemicals in my mouth. The kit comes with plenty of product (up to 50 treatments), and the syringes have clear markers so it’s easy not to waste gel. For the price, this feels like professional whitening results at home. I’ll definitely keep using it and plan to buy refills when I run out. Highly recommend if you want a brighter smile without paying hundreds at the dentist!

I have very stubborn teeth. Nothing has ever worked. I have used the high dollar products that my wife uses and they do not work for me. But, they do work for her. I even spent $700 at the dentist to get my teeth white twice. It did not work. And, I have very sensitive teeth. This worked. I am giving it five stars because it really does work. I noticed a difference after the first try. I am now at the third try. My wife noticed a big difference. Thank you Amazon for introducing this to us. And, thank you for giving us a teeth whitening treatment that doesn’t really hurt.

I've done at least 7 or 8 treatments consistently and have switched to drinking less espresso, with more cream, through a straw (the next day. I don't eat for a whole night after doing my treatments.) My teeth don't seem too much lighter than before. Also, if this touches your skin and remains on it for more than a few seconds, your skin will start to react and burn. I wasn't able to wash it off easily once it started reacting. So make sure the gel doesn't get on your skin. Use gloves. Also, trying to shape the molds was a pain, and so was trimming them after. I had to submerge them in water over and over again because they struggled to take their shape. You may need to keep them under longer than recommended by the instructions. I am updating my review because the seller offered and provided a full refund for the product, as I was dissatisfied. I appreciated that and am awaiting any guidance they can give to make my usage of the product more effective.

Use a tiny bit apply directly to your teeth … than a tiny more “Tiny” in tray. Do not allow on gums, as it’s strong but seems to be great. The Neg reviews about burning I’m sure are using too much! Disappointed no blu light or color chart to compare progress….will update….only 3 days
