ACC to ur description it looks like recavitatikn must have happened little deep affecting the nerve tissue of that particular tooth.u might need root canal treatment ,visit a dentist

A permanent filling in the tooth does not ensure that Cavitation cannot occur again. It seems that your tooth is affected by Re Cavitation and the damage is deeper this time involving the nerves and causing the symptoms. Going by the description it seems that your tooth is affected by Irreversible pulpitis and will require root canal treatment of the same so that permanent relief of symptoms can be achieved and the extraction of the tooth can be avoided.
