The reason you drool is that you sleep with your mouth open.
You couldn`t drool if you slept with your mouth closed and breathed through your nose. My son sleeps with his mouth open and drools. This is hereditary on his part because his mom (my ex-wife) was also an open mouth sleeper and drooled. They are also very heavy sleepers which may have something to do with it.
Perhaps TMI, but I got an ortho expander at the top of my mouth which caused me to begin making excess saliva, and no I still have that even though the expander is out.
Occassionally, (once/week, in public), I’ll be sitting in class with my mouth open when disaster strikes, and I’ll always realize it in that split second between when the drool leaves your mouth and it begins its long, precipitious descent onto the desk, leaving me crying out in my mind,
But it’s too late.
Any suggestions? Does changing tooth-paste really make a difference?
