I had two fillings done 6 days ago. the night of had some aching on teeth had been worked on but the next two days were fine. since tuesday though it's really sensitive after cold or sweet things and achy pain lasts few mins to few hours. normal?

Sometimes: Sensitivity after fillings can occur off and on sometimes for a while, so my dentist tells me! It is a good idea to call your dentist about this to see if it is normal in your case.

Fillings: You had surgery done on 2 teeth that were already compromised by infection. Post-surgical sensitivity is to be expected. If teeth respond well the sensitivity may already be demising. If not, call your Dentist. May need microscopic occlusal adjustment. If worsens, May need root canal treatment. In any event, call your Dentist and report your symptoms.
