Who do I need to see? Dr or dentist?

I would say go to the dentist! It sounds like a possible infection - maybe try gargling strong mouthwash and see if that makes it better?

Definitely make an appointment to see a dentist though xxx

I would go for dentist if it's your gums.

Hope you get it sorted soon - sounds horrid, poor you!

Thanks both - will give the dentist a ring tomorrow!
