JMU 3Pcs Dental Cheek Retractor C Shape Mouth Opener Size Medium+ Small+ Large, Clear

These are fantastic when laser whitening teeth at home. The different sizes are great so that you have options. They are good quality as I've used them a number of times and there has been no problems. Before I would hold my mouth open for the 25-30 minute laser whitening and this product does it for me. They are perfect and a must have item.

I had stopped using my teeth whitening strips because it was too difficult to keep them in place for any length of time. So I thought I would give this item a try since that’s what the dentist uses. IT WORKS GREAT and I didn’t have to worry about ordering the wrong size since there are 3 sizes in the package. Whitening strips stay in place for at least 45 minutes now! Also provides me with my laugh for the day when I look in the mirror. No video with this review…LOL!!

I love these but be careful of the big one -it breaks easily.

Great for whitening and easy to use! Loved the multiple sizes!

The retractor does a good job of keeping the mouth open. I used the smallest one of the three, but the plastic is hard and was very uncomfortable on my gums. I do have a very small mouth, so I will be looking for a silicone model.

A dental hygienist on youtube recommended this product to those who use whitening strips to whiten their teeth. Apparently, using this plus a whitening strip is very similar to an in-person dental treatment, and it helped me minimize getting saliva on mh whitening strips.

Item came with dust, dirt, and debris on it. Ewww! This is an item that goes in your body so I don’t know how this got shipped out without them being clean. totally disappointed as others said they received them in excellent condition.
