First let us separate two things: sensitivity in the tooth for a few days after a root canal is expected; as the tissue heals, the feeling usually fades on its own. What I really care about is pain that persists after weeks or months, that stabs when you bite, or that comes and goes with swelling.

Pain like that usually has a cause, and the cause can be found. The ones we meet most often are a canal missed in the first treatment and left untreated, an area inside the canal that could not be cleaned, a filling that has started to leak over time, or a crack in the tooth. Examination and X-rays together show which of these we are facing; and the microscope is our greatest ally, especially in finding hidden canals.

So do not sit and wait, thinking 'the root canal is done, why should this tooth hurt at all'. Persistent pain is a message; finding its source is our job.

The most misleading moment in tooth pain is the moment it stops. A good share of patients decide the problem is solved once the pain settles, and cancel their appointment. Yet when a fiercely aching tooth suddenly goes quiet on its own, it sometimes means the nerve tissue inside has lost its vitality. The pain has fallen silent, but the infection has not; it can go on advancing quietly in the bone at the root tip.

The same illusion has a version inside treatment too: when a root canal takes several sessions, a patient who feels relief after the first may not come to the rest. A temporary filling is exactly that, temporary; a tooth with its treatment half finished does not count as healed just because it does not hurt. I tell my patients this: pain is an alarm bell, and the bell going silent does not mean the fire is out. Show the quiet tooth to your dentist too; the real picture is told not by pain but by examination and films.

A patient arrived with an X-ray in hand; at an examination elsewhere a fractured instrument had been seen in the canal of the tooth, and they believed the tooth had to come out. A broken instrument sounds frightening, and the patient had already said their goodbyes to the tooth.

I assessed it under the microscope and told them two things at once: that attempting to remove the instrument was possible, and that there was no guarantee. We also agreed from the start that the attempt had a limit; if we began to harm the tooth, we could stop. After that openness, the patient wanted to try.

It was a calm, long session. When the instrument came out I showed it to the patient on the microscope image; seeing that tiny piece of metal, they laughed and asked to keep it as a souvenir. We completed the treatment, and the fragment stayed with them. What was valuable to me in this case was the conversation as much as the instrument: when you can give a patient the hope and the limit in the same breath, the decision becomes truly theirs.
