Teeth Whitening Trays Moldable – 4 Custom Dental Trays with 2 Black Retainer Cases, Thermoform Fit for Bleaching Gel, Compatible with Opalescence, BPA Free, Trimmable

These are great. Super simple to use and easy to understand. Definitely will order more to give as gifts. Have gotten a lot of compliments after using.

They work alright, but I had hoped the trays would be firmer once molded to my mouth. They feel a bit flimsy, so while I am using them, I must bite down the entire half hour the whitening gel is on my teeth in order for them to stay in place, which makes the jaw very tired. I'm not sure if this is normal, but the ones I've had from my dentist in the past have been easier to use and just stayed on without effort. These aren't bad though, especially considering the price.

This worked great for me! The trays are soft and bendable so it did not hurt my teeth or mouth while I was using them! I also really like the case so I can easily take them when traveling!

I wasn’t the biggest fan of these they are kind of big and slip all over. I used these for teeth whitening. I’m not sure what exactly I was expecting but if your looking for something cheap to use to put whitening gel these are it.

I lost my fitted tray for whitening so i thought I would try these out. They are big, they hurt the sides of my mouth. The material squeaks in your mouth and makes that awful squeak sound. My teeth dont sit in them to where you arent losing all your whitening product. Im disappointed for sure

I don't do the whole teeth whitening thing (can't, really due to having a few implants and crowns towards the front of my mouth that can't be whitened.) My (now ex-) wife would tell me that I ground my teeth "loudly" at night, and my dentists over the years have all mentioned that there's tons of grinding damage to the tops of every tooth... so I've been using mouth guards for a few years and like to replace them every six months or so. These are easy and quick to form/mold and fit great.

I wasn’t able to get these to work for me, but that might just be my teeth—they’re not the straightest! The process is easy and straightforward: you form them, drop them in water heated to the right temperature, and place them in your mouth to mold. While it didn’t work for me, it could work for others.

I was looking for a replacement for my whitening trays and these are the perfect ones. It comes in multi pack so you have plenty works with my current whitening for my teeth and it’s easy to just pop them in like my teeth rinse them out. they’re pretty sturdy so I think that they will last for a good amount of time. Easily washable for multi use and good for replacing what I had before.
