Mouth taping during sleep can help individuals transition from mouth-breathing and snoring to nasal breathing.

“Many people, however, are starting to do this thing of taping their mouths shut, now, this sounds a little bit extreme, and you certainly don't want to do this in any way that's dangerous. James Nestor talked about this in his book, "Breath: The New Science of a Lost Art," that simply taping shut the mouth, with some tape that will allow you to open your mouth if you really need to, during sleep can allow people to shift over from being mouth-breathers and snorers to nose-breathers.”
