root canal

Hi, I have had the root canal procedure twice on a tooth over the past
two years. I only had temporary filling both the times. The last time
I lost the temporary filling was about 18 months ago and the tooth has
been open ever since. Now I am having pain and not sure whether it is
because this open tooth or any other tooth. Do you think I need the
root canal procedure again for the same tooth?

If I see a dentist and if he thinks I need the root canal procedure
again on the same tooth, should I always belive him? What if he is
trying to sell the procedure just to make more money?

Please help me with these two questions.

Thanks.

A tooth that has been open to the mouth for 18 months?  In general, a
long-term *very, very* guarded prognosis.  Please understand this when
speaking to your dentist.

IIRC it's 30 days and you will have bacteria to the apex
with GP and conventional sealers.

I say re-treat ! and be sure to get the crown soon !

Even with retreatment and a crown, it still has a very guarded prognosis, in
my opinion.

Would like to see a radiograph before making that judgement.

I'm not sure how much more info it will give you.  If the apex does not show
widening or a radiolucency, does that make the prognosis better?  I don't
believe so.  In my opinion, 18 months of bacteria all the way to the apex
says it all.  Sure, go ahead and try the root canal (if the tooth is even
restorable or endodontics actually possible), but best the patient know the
odds...this situation is not like the average endo.

    I've done endos on non-vital teeth where the reported provocative
incident was 12 years before (a baseball bat).  The area was the size of
Kansas and the smell on opening was indescribably.
    I'm with Newbie--if the tooth is restorable, the duration of bacterial
percolation should not be the deciding factor.

Have retreated endos before a crown replacement that were
a bit funky on the inside. If after removing the crown and
any build up material the GP looks stained and has an odor --> retreat.
Afterall a crown failure is usually due to leakage and/or recurrent decay.

Duration of infection is no contraindication to RCT.
