A few reasons I find the use of a pacifier might be good.
Stops night time teeth grinding.
Helps prevent snoring
For me it stopped my night time drooling
Helps prevent dry mouth.
Helps to stop tong clicking.
These are just a few reasons I find my use of a pacifier good.
I have found that I sleep better now that I'm using one.
If any one else knows a good reason to use one please share.
