You're all so lovely, thanks! Slept a bit, and woke up much better. The pain has gone! Still very bruised, not my usual dentist, this guy had a rather rough manner! He had to inject more into the root, which really did hurt, but then went numb. It had a lot of infection, thanks for the info on the anesthetic, he said it probably wouldn't work well, but didn't say why!
This is the 4th of my back teeth to go, needing root canal. Dentist is non plussed as my teeth are really good, but I think it's two babies in 2 years that did it, they all went after dd3, I was very run down for a long time.
Now I can think straight I'm catching up on all yesterdays housework jobs. It has been a nsd, because I forgot my purse, just as well, heaven knows what I would have bought this morning, I was in such a state.
