Any question answered...

It isn't general anaesthetic, it just sedation, so you're still conscious, but yeah the dentist seemed to imply it wasn't worth it. 40 mins is about the limit of what i could bear though.

If it doesn't hurt it doesn't hurt I guess, but I'll sleep on it. Thanks for advice again.

I've had a lot of work done over the past year- two teeth that were broken off flush with the gum line had to have the roots dug out, then once the bone healed I had metal pegs screwed into the sockets.

Also inlays/major fillings to a large percentage of my teeth.

Everything (bar the original wiring up of my broken jaw) was done with local anaesthesia, just make sure that you go to a dentist that you are happy with.
