Dental Insurance Plus, Toothache with old filling
Question: I had a filling done around two years ago, about two days ago I started noticing some pain like a dull ache. Now today it is very painful. The pain seems to come and go. What can this be it never hurt before now.
Answer: I would advise you to go back to your dentist. Off hand I would say it could be either a new cavity in the same tooth (which does happen all the time) or it is possible that not all the decay was removed when the filling was first done. However either way you need to see a dentist.
Dental pain is not a good sign. It is telling you something is wrong. You do not want to wait until it become a larger issue such as infection/abcess.
