I’m not sure how to approach this. My husband’s breath has gotten terrible. Really awful. I need to tell him but I’m not sure what the nicest way would be. He tends to get defensive and sensitive about things. I don’t want to hurt his feelings but it’s really bad and he needs to know. His dental hygiene is good…brushes 2-3 times a day and flosses, sees the dentist twice a year and doesn’t seem to have any bad teeth. I’m thinking either tonsil stones or his coffee habit. Any advice….please??
