My Husband has BAD Breath
He uses a cpap (?) machine for sleep apnea; he has allergies; he goes to the dentist twice a year and was just there about a month ago and all was well dentally. He flosses daily and uses Listerine (the strong yellow variety) twice a day. His breath could stop a bus. He has a new job that involves talking to people much of the day (!) and I know this problem is NOT going to be an asset for him. I recently purchased a Neti Pot and have been using it for myself; I am going to get one for him and get him to try that; any other suggestions??
