I've been placed 3 unit cobalt chromium pfm dental bridge in upper right side. The abutment tooths containing first molar which was previously restored with composite resin filling (deep filling). After preparing the tooths doctor placed temporary crowns in that place. That time also that molar tooth sensation was there. Doctor, said in absence of accurate margins it may happen. Now after placing the bridge with gic cement permanent on 20th april (last saturday), from last 1 week I feel painful sensation to that tooth always. When consuming any cold food it increases intensely. I've asked doctor he told me to do opg and examine the bridge thoroughly and said placement is perfect. He saying it may be the pulp got inflamed during tooth preparation. Take 2 flexon each day for 3 days. If sensation still there then need to do rct. Already I have spent inr23000. Now he is saying he will drill the bridge and do rct. The bridge integrity will remain intact. Please tell me this sensation is normal. What should I do now? Please suggest.
