Thanks for the tip paddster16.  My husband's appt. was canceled until next week.  I'll still report on it when it happens.

However, what if he sleeps with his mouth open?  He has lots of allergies so breathing through his nose isn't always easy (although sprays have helped).  Do you know if someone is a diehard mouth open sleeper that this guard would help? 

I'm willing to spend the money but if it would just be wasted I don't want to do that.

Thanks.  *Kat
