Another root canal is complete!

Has anybody else had three root canals on the same tooth?? Or is it just me?

Root Canal #1- December 2010
Root canal #2- Two weeks ago
Root canal #3- yesterday afternoon

Seriously!  I even went to a root canal specialist for these last two root canals, he found an extra canal, so that explained why it had gotten infected.  But for the third time? He doesn't know.

As he was in there yesterday, he said he didn't notice any cracks in my canals and everything looked fine. He said it is sometimes hard to get rid of bacteria.

I have also had a lot of sinus and eye pain, but he doesn't think it's related, BUT he wants me to get that checked out before he does the final filling.

If my infection does not go away after this root canal, he says we will need to pull the tooth. :(
And since I am so young, he said my teeth would surely move, so I would probably need to replace the tooth with an implant. Sounds like fun, doesn't it??  This is also the same side that I have so much TMJ trouble on, so I definitely don't want to mess that up any more either!

(All my TMJ trouble started when I originally cracked this tooth back in February of 2010!!)
