Moldable Teeth Whitening Trays for Gel Customizable Dental Mouth Guards - Compatible with Opalescence and All Gels - 4 Trays & 2 Storage Cases Thin, Trimmable, BPA-Free

I am one of those who usually don't write any reviews but this time I decided share my experience because what I read really helped me, so I am doing my part. Starting with the very obvious question : Yes, this stuff really works. I decided to go for the gel and tray kind of kit because I the strips did not really deliver the results I wanted. And I was kinda in a hurry to get my teeth white in 2 weeks or less. And I wanted to give this particular kit a try because of the cost, the fact that this is a complete kit with everything I needed and the good things people wrote. I do have sensitive teeth and I didn't want a product that will cause me any pain. The how water moldable mouth-trays were OK, you need to remember not to use boiling water - it needs to be hot but not that hot. Once you get them soft in water, you just press them against your teeth and suck the air out, shaping them to your teeth. You make the shape so that you can put the gel in. You will also need to trimming the trays a bit so that they don’t push into your gums - well may be you have huge teeth - IDK. Since, I am a bit weary about my sensitive teeth, I didn’t leave the gel on more than 15 minutes. But I think i would be OK with 20-25 minutes. Doing this every other day, 15 minutes was long enough my teeth white. To make sure I don’t get any gel on my gums, I made sure to use just a little bit of drop in the front of the tray, a drop per each tooth. When your tooth touches the gel drop, it spreads all over the tooth. No need to overflow the gel because you have to avoid getting the gel on your gums. Unless you want uncomfortable gums for a day or two. It burns and turns your gums a bit white. Now that I am extra careful about the gel burning my gums I tried putting a little vaseline on my gums before I put on the trays. The vaseline is like a protector. I was able to get my teeth white in less than 10 days. And I still have a ton of gel left. This was a very good deal and I am happy with my results. Hopefully, this helps others who are thinking about buying a teeth whitening product

These trays mold to my teeth easily and stay in place, making whitening much more comfortable. They’re thin, BPA-free, and come with storage cases. These trays are exactly what I needed for consistent, even results. Even when using the film whitening strips, I use this over them to keep everything snug and in place.

I replaced molds from the dentist with these to whiten my teeth. They’re much thicker trays than what I had- and didn’t get the snug fit that I was hoping for. As long as I’m only wearing for a short time they’re fine, but no overnight wearing.

A little difficult to work the bottom teeth, but if you follow the directions exactly it will conform well. Top teeth tray came out well.

In 2015 I bought a whitening kit that contained syringes filled with 35% carbamide peroxide that burned like crazy. As I recall, I wasn't seeing noticeable results after using two or three tubes, so I decided it wasn't worth the pain and threw out the rest. Because of that experience, I was prepared for significant burning from this 44% carbamide peroxide product. Therefore I was surprised to find no burning at all, not even when used twice as long as instructed. NONE. I had to hot-dip the trays twice, and the second time one of them deformed and couldn't be fixed. I emailed the company who immediately sent a replacement set. Later I had a product question so I sent another email - the seller did not respond. I began cautiously with the recommended 15-minute treatments, which I continued with through #18. I was seeing little, if any results, so from #19 thru #30 I did 30 minutes each. Still no progress. I must have been using the gel more sparingly than intended, because I got 30 treatments out of 4 syringes. I was ready to give up but decided to open the last tube anyway. I did two treatments of 15 minutes each, and then tossed the remainder in the trash. I don't think I received any benefit at all - my teeth aren't any whiter. They were on the darker side of the chart when I began, so plenty of room for improvement. But when I finished, my teeth seemed to be in the same spot on the chart - possibly a shade whiter. I don't smoke, don't drink a lot of coffee and not much cola. My teeth are in fair shape and had been cleaned a few months before the kit arrived. Because there was zero burning sensation and little to no whitening, I have serious doubts the product contained the stated amount of peroxide. It was certainly a waste of my time and money.

Needed an affordable night guard due to grinding my teeth. This one works great! It's comfortable and fits well. The moldable process was quick and simple. It's nice that there were different sizes included. The travel cases were a very nice addition. Good product, for a great value.

Doesnt even go to the molars, let alone the rear most molar. Followed all instructions perfectly too. Garbage

I've purchased custom whitening trays in the past - I don't remember the cost, but it was over $100 decades ago. I don't know if the cost has gone up or down, but I misplaced mine and ordered this. The set is easy to use, but you need a thermometer to get your water the correct temperature. I did not use a thermometer and it made the process more difficult since I overheated the guards. They get REALLY flimsy and stick to itself if you overheat them. I was able to get them unstuck and molded into a useable guard. You can actually thin the guard down a bit while it's hot. I don't think there is anyway to get these as comfortable as custom made guards, but it's easy to get something completely useable during the day. I don't know about using these overnight - they don't get thin enough where I found that comfortable. Completely worth the cost.
