Eruption cyst?

I’d definitely contact babies pediatrician ASAP

So I ended up being very stern at the GP surgery first thing this morning and got seen! He said it’s an infected abscess and gave me some antibiotics! She’s still not touching solids or putting anything in her mouth, and is in a lot of pain.
He said there’s nothing the dentist could have done as it needs antibiotics and that it should drain itself once the tooth pierces through. He also apologised for her not been seen on Friday!
It has however spread across her gums and he said to monitor her symptoms and call back, or out of hours, if she worsens as she may need the gum slicing so the tooth comes through and it drains

Poor baby :(
