Cool Teeth Whitening 5 x 5cc Tubes (25 Applications) and DIY Trays Included Fast Carbamide Peroxide Whitener Tooth Bleaching Gel Syringes At Home Use Refills Professional Dentist Grade, Enamel Safe

I had the Smile direct club LED tray with their generic whitening gel.. this stuff is easily 4x as powerful. I've used this 4-5 times and still have some left in the 1st syringe. My teeth are 100% whiter, idk like 5 er 6 shades? and I drink espresso and vape everyday. After my 2nd session my teeth were sensitive to cold drinks, I took a few days off and haven't had the issue since. Legit the only whitening system you will need! After a session my teeth feel so polished and clean its like coming home from a dentist cleaning!!!

Excellent teeth whitening kit! I'm very satisfied with this product. The gel is easy to apply thanks to the syringes, and the trays are comfortable to use. This is the second time I've bought it. After just a few treatments, I noticed my teeth looked whiter, and the coffee stains started to fade. I didn't experience any significant sensitivity, and the product lasted a long time, as it contains enough gel for many uses. The price-quality ratio is excellent, and the results are comparable to much more expensive treatments. I would definitely continue buying it and recommend it to anyone looking for effective at-home teeth whitening.

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 love this product. I have been using it for three months now twice per week since I took my braces off and I have noticed a change. My teeth appear to be much whiter. I would recommend this product to anyone. My only issue is that it can be messy due to it being difficult to spread in my retainer and it also causes extra saliva when in use. But all in all, it is a good product.

I've been very impressed with this teeth whitening gel. It worked much faster than I expected, noticeably reducing coffee and food stains after just one use. The application was simple, and although I experienced mild sensitivity initially, it disappeared quickly. A small amount goes a long way, making the kit an excellent value for the price. My teeth looked brighter and cleaner in a short amount of time, and I plan to use it periodically to maintain the results.
