GXXMEI 21PCS (7 Medium+7 Large+7 Small) C-Shape Teeth Whitening Cheek Retractor, Autoclavable Dental Mouth Opener, Disposable Dental Lip Cheek Retractor for Mouthguard Challenge Game

Really useful for cleaning, whiting, and photographing your teeth without the cheeks and lips getting in the way

Buen producto y resistente, como se indica en la descripción. Viene con 30pcs 10M 10S 10L.

These were very flimsy, and were way too large to fit into my mouth.

I needed these for teeth whitening... and they are perfect for that. they are slightly uncomfortable and I needed to put a lightweight small rubber band around the guard to minimize the how wide it was... but wit lh that tin modification they were awesome. priced right, the package comes with plenty, but you can also reuse them by just rinsing them, especially if you're using them for personal teeth whitening like myself (so like I said you've got PLENTY, and you won't be running out anytime soon.)

If you are someone that likes to use teeth whiteners but or unable to keep your lips away from your teeth this is for you! This is perfect to hold back your lips to ensure that you place the tooth whitener perfectly! They are a nice thin but thick plastic and font hurt your mouth. I have a small mouth and they still fit just fine and comfy. They are easy to clean also!

These C-shape teeth whitening retainer is a great way to keep the mouth open when applying the chemical agent to the teeth. The three different sizes make it easy to find one to fit one's mouth size. I just don't see other better tools to address the same intended use case.

I received c shaped cheek retractor undamaged in a bag and separated in ziplock bags.They're made of really hard plastic that you can bend to insert in the mouth as needed.They really help retract the cheeks to take a closer look at the teeth rather than using your fingers or can also be used for teeth whitening.However the shape and the size (even with the varying sizes) were a bit awkward for me. I ended up using it once and decided it wasn't work the effort and discomfort. However it does do what it says it will do so I think overall it's an ok product at best. You also get alot of them.

There were 21 cheek extractors in the set which came in small, medium, and large. The extractors are thin and are easy to place in your mouth. They did a pretty good job at exposing my full set of teeth. There was no uncomfort while I was using them. These are also good for when you are playing the challenge game. Overall, they are good extractors and they work as advertised.
