HiMo Dental Cheek Retractor C Shape Mouth Opener Size S,M,L, Pack of 3

Needed it for teeth whitening. Not sure what those other huuuuge sizes are for! Used the smallest one. Found myself referring to the picture to rmbr how to use it properly. Does its job.

Great Product. I use this to help brush my adult son who has severe special needs and am able to clean his teeth with this mouth opener.

I use these while whitening my teeth and it makes it easier and more comfortable to keep my mouth open while putting on the gel. They come in three different sizes so there’s no guessing the size you need to order and for the price you can’t go wrong.

I bought these to keep my mouth open wide for when I used my whitening strips. They worked perfectly, although my keeps were pretty sore after wearing for about 15 minutes.

I purchased this C-shaped cheek retractor set expecting smooth contouring, adequate flexibility, and comfortable intraoral positioning. With three size options included (S, M, L), I anticipated better adaptability for different mouth openings. The overall usability did not meet those expectations. The primary issue is rigidity. The material lacks sufficient flexibility, making insertion less comfortable than it should be. Instead of conforming naturally to the oral anatomy, it feels stiff and creates noticeable pressure at the commissures of the lips. Edge finishing is another concern. The borders are not as smooth as expected for a device intended for intraoral use. While not sharp, the edges feel slightly firm against soft tissue, which reduces patient comfort during extended procedures or photography sessions. Size variation is present, but the dimensional differences between some sizes feel minimal. The fit does not significantly improve when switching between them, limiting practical customization. In addition, the material surface tends to attract moisture quickly, and once lubricated by saliva, positioning becomes less stable. It occasionally shifts, requiring readjustment.
