thanx for sharing your concern,
you have mentioned that you have got six fillings done. so, in that you have to trace which tooth is most painful.
after tracing it, get the filling removed. if it is temporary, on your own else you need to visit your dentist
. once the filling is removed you will have great relief.
the reason for pain is, now your infected tooth is behaving like a closed chamber.
where pressure is built up from bacterial products. once it is opened all the infected material will be pushed out.
after that you can take an xray and then discuss it with dentist , like PULP CAPPING or RCT
meanwhile take tab combiflam
500mg every six hourly. hpe
it helps ,
