😷 Bad Breath!

I have told my husband repeatedly about his breath. Idk what the problem is he goes to the dentist uses mouthwash, gum etc. has never had tonsil stones. It's disgusting where I don't even want to kiss him because then I'll smell like his bad breath. His mom and grandmother have also said something to him. This bothers me because he loves to socialize and works with the public. What else could I possibly do?
