root canal

[Katy47]

I went to an Endodontis b/c my regular dentist told me that one of my teeth, that used to be sensitive to pressure but was now hardly sensitive at all, appeared to be dying and that I might need a root canal.  Again, I was really not having any pain at this time.  The Endo declared, after xrays, that I did indeed need a root canal and he did the root cana at that time, removing two roots. (#3 tooth).  That was 4 full days ago. I have been having this throbbing dull pain in my tooth and along the whole side of my face where the root canal was done...even in my ear.  Is this normal?  I am on antibiotics (clindamycin) and advil 4 times a day.  Please advise.  
Thank you.

Well from the sounds of it the nerve must have been dying for some time. It is possible for the tooth to be completely asymptomatic sometimes.
As for what you said, it troubles me a bit, that tooth  normally has three and if young enough 4 canals sometimes. Now do you remember the Endodontist saying anything about calcification of one canal? that is possible also, but they normally would mention those facts to you.
the meds seem right, I would use the same combination, but the throbbing is not normal. Soem soreness, is normal, but not throbbing. Call the office and ask if they filled two canals or three? and mention that you are having severe throbbing pain. Something tells me they might have missed a canal..
Hope this helps. Feel better.
