Hi Pamela, and welcome to the comments.
I'm concerned that there may be chronic inflammation here. It's not the tooth color, but the gums being swollen and red that makes me say this. Along with the foul breath.
I'd pursue a full mouth exam, which would take some light sedation. They have safe, reversible drugs these days (you should completely be upfront and disallow ketamine, however!). If they find some teeth that should come out, they can take the necessary precautions I mentioned and get that done as well.
Odds are, she'll have a far better quality of life going forward if the teeth that need to come out are attended to. And I'm guessing they'll find some. I could be wrong, but you'll know with a good exam, maybe some radiographs to assess root integrity.
Obviously: no vaccines! At her age, way more risk than benefit.
All the best to you and Baby.
