question: I had a root canal treatment (BMP) done a week back and had some pain in the following days along with swelling of the face (same side). I was told by the dentist (on phone, when i explained the problem) to have Clavam 625, twice daily for 5 days. The course got over yesterday but the swelling is not completely over. It is much better now (i would say 80-90% better), but some discomfort in the jaw joint while opening the mouth to full extent and I feel a funny taste and bad breath in the mouth too. I am due to meet the dentist again this week for crown cutting. Should I be worried about my present dentist or take a second opinion. Also, please note that my root canal was done on the upper tooth, right adjacent to another tooth where an earlier root canal had been performed, with post and crown around 5 years ago by a different dentist. thank you.
