I thought root canal removed the nerves that cause pain

    I had a root canal and crown 2 years ago on one of my molars. Good job or so I thought until this last week. I now have re-developed sensitivity to hot and cold in the same tooth...the very same symptoms that led to the root canal initially.

    Heading back into the dentist on Friday to investigate but what could possibly be happening here?

    Thanks

    It may feel like it is coming from the root canal treated tooth but it is most likely coming from the adjacent one. Your dentist will test this by applying cold air to the other teeth to reveal the source of the sensitivity.

    It turns out that the sensitivity is not from a tooth that has a root canal and crown. It's from a tooth with a filling...2 years old. If I recall it was a replacement filling by my current dentist. There was talk at the time about a little crack in the tooth. Fast forward to today, the tooth is becoming increasingly sensitive to hold/cold/pressure. It's not too bad but it's noticeable and therefore slightly annoying (tending to chew on other side of mouth). Last week the dentist said to leave it until after xmas but that an implant may be the solution.

    I didn't ask her: why not root canal? I'd prefer to keep the tooth. Are there cases where root canal is not suitable and an implant is the only answer? This tooth is not rotten to the core or anything...just a deep filling.

    Thanks.

    A root canal is only worth your effort and expense of it has a good long term prognosis. If there is very little of the tooth left it is likely to fracture more after root canal and then need to be removed. If your dentist doesn't think it is going to last long, she is advising against spending more of your money on it. You can of course insist on a root canal rather than an extraction but you would then have to accept the limitations of the treatment and the loss of both your tooth and the money paid for the root canal if/when the tooth breaks.
