Could pulsing/pain in the tooth still be present after RCT, even after the pulp has been removed......... if one of the canals wasn't fully treated?

[ToothPatient]

Tooth being an upper 2nd molar.

I know the endodontist missed MB2, he found the entry, but didn't treat the entire canal cause he said he couldn't get his file in easily, so he just left it.

Pain I had prior to the RCT is less, but not gone, and I'm getting that pulsing pain in the root area of the tooth still.

He seemed to think that having removed the pulp, any pain inside the tooth should be gone, and the abscess and all associated pain should have cleared up.

So in short, if MB2 canal wasn't entirely treated, can the tooth remain painful, even if all other canals and the pulp has been removed?

Or is that unusual?

Not fully treated canal in question.

Yes, any untreated canal could lead to the symptoms you are experiencing. If he has trouble navigating the canal, he should perhaps refer you to someone else. You get some endodontists who perform these procedures under a microscope, and you get modern, super flexible files, that make navigating a difficult canal easier. Some endodontists also use a laser as an adjunct in order to increase the disinfection process of the canal.
