### input:
I am being treated by a dentist for an infection for the past 2.5 months. The infection is still there and I am on antibiotics. Now I feel the pain in areas beyond where the tooth was and I cannot open my mouth fully.  Should I go back to my dentist or to an ER?

### output:

Hi... Can understand your concern... As per your query about tooth infection which is being treated for about 2.5 months. I wish to have details like your age and weather any X-ray of the infected tooth was done? Which antibiotics and painkiller you have been prescribed? Lf you are an otherwise healthy person, it seems that the antibiotics which you're being prescribed is not providing effective coverage .you are also not able to open your mouth because of inflammation in involved area of the infection may have spread a little more and due to proliferating bacteria... There is need to change the antibiotics along with some strong analgesic like tramadol with serratiopeptidase to reduce the pain and inflammation...Also, after the infection subsides you need to take its appropriate procedure like root canal or extraction etc. for a permanent remedy. Infections some times may traverse the tissue spaces in oral cavity and can cause much serious condition, and sometimes it can also reach bloodstream and cause more serious conditions, so appropriate treatment is needed soon. I suggest consulting your dentist again and ask him for change in medications and dosage for an effective treatment.Also, if you are not totally satisfied with him, you can go to ER.or an oral and maxillofacial surgeon who will evaluate and diagnose the condition properly. I hope the information helps you. You are welcome to have any further query... Take care.
