Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that pain after
Root Canal filling that is not being relieved even after taking medication can be either due to infection below the root tips of tooth that has not yet resolved and filling is done over it leading to pain..
Other reason can be that any root canal is missed accidentally from cleaning and filling and as nerves might be present in it alive leading to pain..
I would suggest you to consult an Endodontist and get evaluated and an
x Ray can be done to look for exact cause of this pain and treatment can be done accordingly..
In case of infection removal of filling, re cleaning the canal, continue Antibiotic and painkillers and filling again once infection subsides is done..
In case of missed canal, locating the canal and cleaning and filling is done..
As of now take higher painkiller like
TRAMADOL or
Ketorolac to relieve pain..
Hope this information helps..
Thanks and regards.
