Teeth Whitening Gel Refill for Trays - Professional Strength 44% Carbamide Peroxide Formula - Fast & Effective Bleaching Solution for a Brighter Smile

Good whitening product, smells good and comes with one tray to use. Has shade reference and directions were easy to follow after using almost every day for a week I do see a lighter shade, a good alternative to the strips and dentist strength. My teeth are sensitive and it didn’t bother them at all and I’m happy with the results so I will continue to use.

This is a great product for teeth whitening. I didn’t realize how discolored my teeth were until I seen the results of this product. My teeth are about 3x whiter than they were before, after using this gel. The product works really well and the best part about it is the gel is plant based, totally Vegan. It’s very easy to use and comes with many applications for to maintain a bright white smile.

Very good, I recommend it. I've been using it for a couple of days and have seen changes in my teeth, they've gradually cleared up. You have to be very responsible to do the treatment on time and thus be able to see the results. I definitely recommend it.

This is my second set after getting it as a gift. This gel really works! I’ve tried a few whitening products, but this one gave me quick results without sensitivity. Super easy to use with my trays—my smile’s already brighter!

Price is fair, and work as expected. Will buy this product again.

Recommend that you do not purchase but you do you. I had it on for a minute and felt burning on my gums and immediately took the trays out and flushed my mouth with water. Luckily I didn’t get burned too severely and was only sore for about a day but this product should only be used by dentists. Maybe with dentist grade trays that fit your teeth perfectly would work better but I molded the trays to my teeth as instructed and put a very very small amount in the teeth slots and it still was able to get to my gums and cause a good bit of pain for about 30 minutes and soreness for about 24 hours and that was only after a minute of applying this product it also made my teeth start to hurt which means that even after only a minute it was eating at my enamel. The risk is not worth the results for me.

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.

Used it last night once I received it. I can see it already working after one use. I have sensitive teeth and this was perfect. Does not leave my teeth aching after using it. So far, so good with the results.
