Thanks for all your feedback. I think most of the pain that I'm feeling is coming from the tooth that I had filled about 3 weeks ago. To be honest, the one next to it that I had filled on Thursday doesn't appear to be given me too much trouble which seems to be a good sign that one of them might have worked anyway
I spoke to the Emergency dentist yesterday about it and she said that from what I'd described it certainly sounds like the tooth that is giving me trouble has abscessed again. She gave me some more antibiotics and pain medication, and told me to see my regular dentist this week about it but suggested that it might be a good idea that I have it extracted.
It's a shame as this tooth is on the front lower jaw so it will look terrible with a gap in it but a friend told me that you can sometimes have a bridge built or something like that to cover the gap - is this correct?
Thanks.
Ian
