Failed to load media. The instructions were pretty easy to follow. Heat the water to almost boiling, 190 degrees Fahrenheit. If you don't have a thermometer, simply boil the water and then remove it from the heat until it stops bubbling. Soak the plastic in water for 30 seconds, take it out for a few seconds to cool slightly, then put it in your mouth and quickly mold it around your teeth with your tongue and fingers. It installs in seconds. Then immerse in cold water to fully cure. Ready. I did find that I cut off a few ends at the back of my mouth the first time I used it, thinking it was too long. But it does seem to compress so it actually left a gap and didn't cover all of my teeth, but there was also a lot of extra plastic building up on the roof of the mouth which was irritating and making me uncomfortable. The second time I cut off the entire inside edge but left the same length. It seemed a lot better. I think I could have trimmed more but that was ok. Another tip: you CAN use scissors, but I've found that meat scissors cut through meat more easily. With regular scissors it was too difficult for me to cut everything out. They contain 4 sets of teeth. So if you don't get it right the first time, you have a few more tries that I found helpful. I can do it again and cut off more before cooking. They also included a handy carry case. I recommend it.
