I actually fully intend to start going regularly after all of this (5 visits in total, 2 for the root canal, the others to repair old fillings, and put in new ones, and one BIG filling - for the tooth next to the one that broke). My 'estimate' reckons just £250 or so for the lot, and (so far) she seems a fantastic dentist and is very understanding.
I still see her with devil horns and so on though.
but thanks guys, I just need to calm down and get on with it. Tough northerner and all that...
