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.

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 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..

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.

This whitening system really works. It's much better than the Crest Whitestrips. I used two boxes of Whitestrips and barely noticed any difference. So I ordered this set of peroxide gel on Amazon for around $13. It's easy to use and the gel is as strong as the gel I got from the dentist 20 years ago. I use this with a blue LED light, which speeds up the process considerably. One hour with the blue LED light is equal to wearing the product overnight. I do this nightly for an hour, with the blue LED light and after about a month my teeth are as white as the lightest shade on the included chart. The light does not come with this set but can be purchased separately on Amazon for just a few dollars. My teeth were quite yellow when I started using this gel, despite using two boxes of the Crest Whitestrips. I noticed a marked difference after a week (approximately 5 or 6 one hour sessions) and continued to notice more whitening as the time when on. Because my teeth were so yellow, I didn't want to wear nude lipstick, which only accentuated the yellowness. I was reluctant to smile because my teeth were so discolored from smoking, tea, red wine and coffee. 20 years ago I did a whitening treatment at the dentists office, which includes custom made plastic trays and whitening gel, which was cutting age technology back then. I'm almost positive that this kit has the same strength of gel as the gel the dentist provided. I have not had any sensitivity at all, which is a good thing. I didn't experience any back then either. The dentist treatment was used overnight and took about two weeks to make a difference. I had to do two rounds of the dentist treatment which cost about $300 in total. Whitening treatment today run between $300-$600 but are done in an hour in the dentist's office. This price is not in my budget but I knew that this kind of whitening gel (44% carbamide peroxide) would work although it would take time. My teeth are now blindingly white but I'm not quite finished. I still use the gel a couple of nights a week, always with the blue LED light. I definitely think the key to successfully using the whitening gel is using the blue LED light. This speeds up the process considerably and I don't need to sleep with these uncomfortable silicone trays. However, if you don't want to get a blue LED light, use the gel overnight if you can stand it and you will get the same level of results. There are other whitening gel kits that come with one or more blue LED lights for almost the same price. I'm now on a second kit that came with four silicone trays, two blue LED lights and the same amount of peroxide gel for the same $20 price tag. So you may want to get that kit instead. The price for the kit I am reviewing here has gone up from $13 to $20. For the same money you can get a kit with the added trays, two blue LED lights and the same strength carbamide peroxide. I will continue to use whitening gel several times a week, just to maintain the whiteness. It really does work but if you want the fastest, best results possible, use this gel with a blue LED light.

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
