Teeth Whitening Trays Moldable 4-Pc Bleaching Trays for Teeth Whitening with 2 Slim Retainer Cases - Comfortable, Thin Design for Tooth Bleach, Compatible with Opalescence Gel Not Included

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.

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.

Bought these for some whitening gel I also ordered from Amazon. Easy to use with clear instructions. Seems like they will last along time. Price point was also very reasonable.

I purchased these to whiten my teeth, but it’s a solid tray. It does not conform to your individual tooth mold.

These are absolutely terrible! They do not mold to your teeth whatsoever. I tried multiple times, using water at the exact temperature recommended and following the instructions precisely. Complete waste of money.

It was really easy to adjust especially with heat to fit. I use them at night because I grind my teeth but also used them for whitening. Don't feel any discomfort and these were way cheaper than getting it from my dentist.

Great trays!! These are easy to use. Easy to place the gel in the trays. The molds are sturdy and don’t hurt my mouth. I can definitely tell a difference after using the trays. I like how it came with multiple trays. They are easy to clean.

I tried a few times to mold these to my teeth. It’s not as simple as the instructions say. They are thick and not easy to mold to your mouth.
