(+26...1) asks how can I tell my girlfriend that her mouth is smelling bad🤢?
The classic way to deal with bad breath is to offer her a mint or some other gum/candy/snack 🍬 that will make her breath smell better. Pop a candy 🍭 into your mouth yourself, and offer her one at the same time. Alternately, you can tell her outright that her mouth smells bad, but say it as nicely as possible. For example, "Honey, lately I've been noticing that your breath smells a little odd. Have you been eating something different/feeling sick😷?" Hopefully, she will go brush her teeth or go see a dentist. If you don't want to confront her outright, you could even try slipping her an anonymous note✉!
