Dental Cheek Retractor, 9-Pack 100% BPA-Free C-Shape Autoclavable Mouth Opener Retractors for Teeth Whitening, Party, Mouthguard Challenge Game (3X Size S, 3xSize M, 3xSize L) (9 Pack)

They did not break in half when using them. Prenty of extras

Comfortably practical.

I needed to hold my lips away from my gums while I cleaned plaque off them and it worked perfect at doing that. The largest size worked best, because I have a big mouth. Cleaning my enamel wouldn’t have been possible without using this aid. Great invention & easy to use!! Thanks & Much Appreciated, David C.

Got for a photo shoot

Loved it!

Trying to whiten my coffee stained teeth, saliva would and natural lip tendencies would the remove whitening gel too quickly from the tooth surface. This simple device does easily and comfortably hold the lips away, allowing time to apply and hold the whitening gel time to work.

These things are not cute nor comfortable, but they do their job! I wear them to bleach my teeth.

Way too big for the average person. Hard plastic was painful too.

Good

Para el precio cumplen su función. Pero no hay que pensar en su durabilidad a largo plazo

Trae tres tamaños diferentes, la variación entre el M y L no es mucha, el platico no es muy delgado pero tampoco es muy grueso así que si lo manipulas fuerte se rompe, yo los uso para verificar mi progreso de ortodoncia y facilitarme el lavado de los brackets así que me gustó
