I have a huge filling in one of my upper back molars that the dentist had to refil a few days ago. He said the next time it caused problems I would need root canal treatment. Unfortunately my tooth is still sensitive and aches so it looks like I might have to go down that route.
I've heard that the treatment can be painful and not always successful.
Has anyone got any good experiences of this to cheer me up?
I really can't face a tooth extraction as an alternative. What a coward!!!
