Root Canal or Take It Out? A Wisdom Tooth Decision

Quick answer: Most painful wisdom teeth are better removed. The exception is a wisdom tooth that is fully erupted, straight, cleanable, and doing real work in your bite — particularly if the molar in front of it is missing. Then it is worth saving.

The call

Menachem, 44, from Beit Shemesh, arrived with a lower right wisdom tooth that had been aching for a fortnight. He had already been told by one dentist to have it out, and had come for another view because he was reluctant.

He was right to ask. His situation was one of the genuine exceptions.

What we found

The wisdom tooth was fully erupted, upright, in a normal position, and biting properly against the upper wisdom tooth. Crucially, the second molar in front of it had been extracted eleven years earlier and never replaced. That wisdom tooth was doing the work of two teeth and was the back stop of his entire bite on that side.

It also had deep decay on the front surface — precisely where the gap had made it a food trap for a decade — with irreversible pulpitis. Roots were reasonably straight on the x-ray, with two distinct canals, and access looked achievable.

Here is the decision framework we used, and it is worth writing down because the answer differs case by case:

1. Is it functional? Does it bite against something and contribute to chewing? An unopposed wisdom tooth grinding against gum is not worth treating.
2. Is it accessible? Can you physically get instruments to it? Limited opening or a tooth tucked far back makes good root canal treatment very difficult.
3. Is the root anatomy manageable? Wisdom teeth are notorious for fused, curved and unpredictable roots. Some are untreatable.
4. Is it cleanable long-term? A tooth you cannot brush properly will simply decay again.
5. What is behind the decision? If the neighbouring molar is missing or failing, the wisdom tooth's value goes up sharply.

He scored well on all five. A wisdom tooth that is partly erupted, tilted, impossible to clean and opposed by nothing scores badly on all five, which is why the usual advice is extraction.

What we did

Root canal treatment over two visits, with a rubber dam and a mouth prop to keep his jaw supported — treating a tooth that far back is tiring for the patient more than anything else. Both canals were located and treated to full length. Then a crown, because a root-treated molar taking that much load without one is a fracture waiting to happen.

We also had the harder conversation about the missing second molar, which is what caused this problem in the first place.

The outcome

Three years on, the tooth is comfortable and functioning. He kept a working back tooth and avoided a surgical extraction that would have left him with no chewing surface at all on that side.

What to do if this happens to you

1. Ask why extraction is being recommended. There are usually good reasons — ask what they are in your case.
2. Ask whether the tooth bites against anything. This is the single biggest factor.
3. Mention any missing or failing teeth nearby. It changes the calculation entirely.
4. Ask whether the roots look treatable on the x-ray.
5. Be realistic about cleaning. If you cannot reach it with a brush, saving it may only postpone the problem.
6. Do not delay while you decide. Get the pain treated; the strategic decision can follow.
