44% 30cc Total Optimized Strongest Professional Strength Carbamide Peroxide Teeth Whitening Gel Syringe Kit Trays and Shade Guide

This stuff is strong! It does burn a bit on the gums and roof of your mouth. I get brief spikes of pain here and there on some of my teeth but only when the trays are in. The spikes in pain only last a brief second and are then gone. It isn't anything unbearable. The burning on my gums and roof of my mouth is because I am probably putting to much solution in. It is slightly uncomfortable but not really painful. Overall I think the results outweigh the costs. First off it is very reasonable. Second off they give you plenty of solution and last but not least is the fact that this stuff WORKS! I haven't even used half of it and my teeth are looking great. I drank coffee, smoked unfiltered cigarettes and chewed daily for years. I always brushed on a regular but my teeth were always dark and stained. I tried other solutions and they hardly did anything. This stuff not only zapped my teeth but also the gaps and spaces between them. Before I had distinct dark spots around the edges and in between each tooth. These are nearly gone. I compared photos of me and my gf. She has amazing teeth and her smile is one of the first things I notice. Side by side my teeth look horrible in past pictures. I took some recently and I can barely notice the difference between mine and her. She says the difference since I started using this is obvious. After using just over a tube I am getting great results. I probably won't use the 3rd tube and will save it for future treatments. If you have stained or yellow teeth and want to improve your look then give this a try. For the price there isn't a better option for improving your look!

It tastes like battery acid and will burn your gums if you get it on them, but as you can see in the picture, it does its job well. Keep a spit cup on hand as the trays and gel make you generate a lot of saliva. Oh, and a rag to wipe your mouth. Then just kill an hour a night with the tray in watching youtube. I recommend getting remineralization gel as this stuff will make your teeth ache without it. I'm talking bad sensitivity. Get the remineralization gel. Trust me. Keep the trays in for an hour at least. The more you put on your teeth per treatment, the whiter they get. Apply directly to your teeth from applicator and use a q tip to spread around. This helps you limit it getting on your gums. Then once you have the trays in place, use a rag to wipe off your gums. Repeat until you've used up all 3 syringes. Its worth it. The before photo is after the first treatment. The after photo is from the very last treatment. My teeth were dark yellow before. Get this and you wont regret it but be sure to get the remineralization gel too.

This system does work well to whiten teeth. I've used it twice (once for 15 minutes and once for 20 minutes), and I'm already seeing a noticeable difference. My teeth are fairly white already, but I've had some slight yellowing around the base of my teeth from coffee, red wine, etc. I've used Crest White Strips in the past, but they have really gone up in price. This system works must faster and gets my teeth a great deal whiter than the strips at a fraction of the price. The only reason I give it 4 stars instead of 5 is that it's very harsh. The first time I used it, I must have put too much gel in the trays, and my gums started burning after a few minutes. The worst part, though, was a needle-like pain in one of my lower molars. I have no idea what caused that, but it became almost unbearable and I had to spit out the trays after only 15 minutes. In reading some of the other reviews, I decided to try applying the gel to my teeth, then insert the trays. That worked much better, and I had no discomfort with my gums. I did still have the sharp pain in my lower molar, though it wasn't quite as severe as the first time. I'll keep using this in hopes that the discomfort will continue to lessen (I may need to just avoid that tooth), because I'm impressed by the quick results. I estimate I'll only need to use it a few more times to get the level of whiteness I'm looking to achieve.

This product is horribly irritating to the gums. I have been using the Plus White 5 Minute Gel for 10 years and really like it. It doesn't burn, or cause tooth sensitivity, works in only 5-10 minutes, and I can see a noticeable difference after only one use. However, THIS product really bothered my gums. Within minutes, they were burning and had become swollen. I had to take the trays out within the first 5 minutes (they recommend you keep the trays in for 20-30 minutes), because my gums were burning so badly. For three days after my teeth were extremely sensitive and throughout the day would begin to randomly feel like little needles were poking into my teeth. I don't know if the reviews are real or paid for, but this is truly terrible product. Pay a smidge more and go for the Plus White 5 Minute Gel. That's what I'm going back to.

This works for me but it works really gradually and SLOWLY. I waited at least 3 weeks to post a review because I wanted to give my honest opinion. So, this works but I wanted it to work a little better. I've bleached my teeth 3 to 4 times, once a week, 20-30 minutes each, and the results are slightly blotched, bleached, teeth. My top teeth show more visible results and I can see on my top teeth small white streaks. I am satisfied, although I expected faster results ..but patience is a virtue. I guesstimate in about three months, with at least 2 to 3 treatments a week, I'll achieve my pearly whites. It does make my teeth sensitive sometimes, but I use sensodyne so its not a problem. I also keep the gel in my refrigerator..
