I had a composite filling redone but it still hurts. what should i do?

See your dentist: One of the most common reasons for discomfort following the placement of a new filling is the height of the filling. Often all it takes is a small adjustment to make the discomfort go away. Other reasons may be nerve irritation due to overexposure to the acid etchant used in the procedure, deep cavity, gaps in the filling, or just transient sensitivity which will go away in time.

See dentist for exam: This problem is complicated. Oftentimes, smallest fillings can result in painful tooth. Bonding of filling requires careful attention to detail, and sometimes pain ensues. Different bonding approach can help sometimes (hard to explain). Ask you dentist about "self-etching bonding agents". Alternatively, the tooth nerve may actually be infected and require root canal therapy.

Wait or see DDS: Wait a few days if it does not get better go back to your dentist or find anew one.

Normal? Likely: This may\may not be normal and may subside in 1 day, two days, or longer. The full answer if far beyond the scope of this type of forum. It is not uncommon to have some post operative discomfort or sensitivity following a new filling. Basically if it's not too bad, wait it out a few days. If it gets worse or doesn't go away within that time frame, call your dentist and ask what he\she suggests.

Wait: Wait a few days. If you symptoms still persist more than a few days see your dentist for an evaluation. It maybe the bite is off.
