However, I think that this dental experience won't be too bad. One of my neighbours told me about this chap and he IS very nice. He spent about an hour today talking about the problem and options. He won't know until the filling is out whether or not he needs to redo the filling or do root canal. So I have an appointment for next week ...and a prescription for a couple of diazepam tablets.
By the way, please DO NOT leave any comments about how awful root canal can be. As a variation on what my dear old mum would say,'if you can't say something good about the dentist, don't say anything at all
