10pcs Dental O Shape Oral Mouth Cheek Lip Retractor Opener Teeth Whitening Fun Game Tool

Worked well to help keep teeth whitening gel off from my lips and inner cheeks. Wonderful product for little things like tooth whitening.

They are so thin that they do not work well.

Excelente

I like the oral retractors but it’s not good for multiple use. In description there is written that we xan use it in autoclave machinr under theb 135 .I’m a manager of dental clinic and my doctors useed them but they were damaged after the autoclave process.So they are good for one use but in autoclave machine they are not good any more

Works great

Bought these to use when whitening my teeth at home. I have a small mouth and thin lips and did not have enough plastic on the inside to keep my lips from slipping.

Purchased these because I am looking for alternatives to classic lip retractors for my teeth whitening business. Unfortunately like many other reviews say, the inner plastic part meant to hold the lip back is too small and the lips fall out. You are able to hold it in if you “tense” your lips around the retractor to hold it in place, but it’s definitely not ideal for clients to be squeezing their lips around the retractor for the entire service. I also found the edges to be a big sharp, not like in a cutting way but more so a digging way. Could be a better design to have more of a slope on the edges of the plastic where the sides of the mouth are held back

Good
