I think you should bite the bullet and tell her.
Someone has to inform her before she can change it.
I would appreciate someone telling me, discretely, my breath smelled.
1. Be nice about it. She will feel embarrassed.
2. Frame it optimally. Don't say she has Roadkill Pussy, but say she has a distinct taste/smell that you've heard is associated with some conditioned. You're not insulting her, you're looking out for her health. She will still feel embarrassed.
3. Discuss it when clothed and away from the bed. This makes it more distanced and thus less emotional.
