Had a filling done on Monday, well actually it was to replace an existing filling. Think dentist drilled down pretty deep and said it was now more filling than tooth and it's possible it will be sensitive and may need root canal treatment or removal in future if it's a problem.
I've had toothache since it's been done, not really painful and haven't needed pain killers but nervous to eat on that side now and worried that it is going to stay like this. But frustrated tbh as I wasn't having any pain before the dentist decided to drill out old filling.
Is this normal after a filling, will it get better?
