If you're here because you've seen some of the hilarious videos featuring the "mouth opener game", there's not much more you need to know. You've come to the right place, and these are the things you need to play the game. Unlike some similar products, these retractors are comfortable to wear for most people over 13 (the game is less fun if it hurts!) and don't unintentionally slip off. If you haven't seen people playing this game yet, you should open a new tab in your browser right away and do a search for "mouth opener game" videos. It's a great game for family gatherings, parties, or any time a few friends get together. In addition to the challenge-phrase game, other fun (and messy) things to try are drinking water and eating. Not just for fun and games, these appliances, technically called "cheek and lip retractors," have serious uses as well. Some people using home teeth whitening kits find that these retractors are much better than the usual trays for allowing you to apply the whitening compound to the teeth while keeping it off of the lips and gums.
