Customer Question
crown and has had root...
I'm 74, and one of my lower left molars that has a full crown and has had root canal preformed became very sensitive to regular chewing pressure a week ago. My dentist looked at it, took an xray and made a determination that I may have a crack that has facilitated infection so I am on amoxicillin and the pain while taking the antibiotic is gone.
Is there any other explanation to my having that severe pain (on pressure only, not while tooth was idle)? My dentist wants to extract the tooth, and do the bone marrow prep for a possible implant.

Hello,

Thanks for putting up your question on Just Answer.

Root canals are blind procedures, and therefore carry a success rate of about 90-95%. What this means is, that in every 5-10 out of 100 cases, the root canal treatment fails and has to be done again.

The main reason for this is that some amount of pulp tissue that was supposed to be removed in the first attempt, gets left behind. This happens because teeth have a lot of variation in their anatomy, all of which cannot be seen on X rays.

The other reasons for your pain could be :

1. Inadequate instrumentation (some amount of pulp tissue is still left , which can be the source of pain)

2. An entire root canal missed (not picked up on an X ray and hence not cleaned)

3. A broken instrument being left inside the root canal which forms a nidus for infection leading to failure of the root canal.

4. The root canal is not filled entirely, which leads to an incomplete seal at the apex of the root, from which leakage of microbial products occurs and thus infection.

Hope this answers your question. Feel free to contact me again for more information. Please leave a positive rating for me if this answer has helped you. I do not get credit for it otherwise.

Good Luck !

Regards,
Dr. Behere

ElanorTracy, CA

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.

JulieLockesburg, AR

You have been more help than you know. I seriously don't know what my sisters situation would be today if you had not gone above and beyond just answering my questions.

John and StefanieTucson, AZ

I have been dealing with an extremely serious health crisis for over three years, and one your physicians asked me more questions, gave me more answers and encouragement than a dozen different doctors who have been treating me!!
