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.

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.

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