Impressive Smile Dental Cheek Retractor Mouth Opener for Teeth Whitening Clear Blue C-Shape (Size S, M, L Pack of 3)

These work perfectly when whitening my teeth! I am glad they came in a pack of 3 sizes because I would not have known what size to order. As it turns out, the medium size fits me best and the large size will be used by my husband when he whitens his teeth. This was easy and comfortable to use and it was effective at keeping the whiten gel from touching anything but my teeth. These are a good value for sure! Only a few dollars and I was able to use the harsh tooth whitening gel safely. They seem well made and durable as well.

Came on time and worked perfectly. Easy to use and easy to wash. Great price! I’m personally using it to whiten my teeth and apply tooth gems. Recommend for an affordable choice for personal use.

I use this to help keep my teeth dry during teeth whitening. It’s not super comfortable, but I don’t know that anything that pries your lips apart for an extended period of time would be. I made the mistake of using the wrong size because I just kind of assumed the middle size would be best, I guess I’m like Goldilocks in that way. So just make sure you try all three.

lo utice para u juego es bueno ya que teia varios size

They worked, but they're really uncomfortable and they kind of hurt. They would be better if they were made of softer material.
