Hello doctor,

I had an RCT done on the lower molar (number 6) two months ago. The file was left inside the canal, which I did not know. It was a mild sensation for a month or so. Then I went for fixing the crown. The dentist asked to cut the gums because enough space was not there for fixing the crown. After clearance of gum, crown was fixed. The pain was not subsiding even after a week. Crown as fixed temporarily to check if it is normal for a couple of days. But problem was out of control. Crown was removed, and canals were cleaned again. But if the effect of pain killer is gone, pain used to go up again every time.

Then, I went to another dentist (endodontist) in his clinic. He performed re-RCT and said that he found another canal that was not cleaned. He did it and said that the pain would subside. But still the same situation. Even if I gently touch the tooth, it is a severe pain up to the tooth's deep root. What should be the cause of it? Is the file left in the canal causing the issue?

Hello,

Welcome to icliniq.com.

It may cause pain if the file is protruding out of the canal, but is not usually the cause. There may be a hidden canal infection.

Usually, such pain is caused when more disinfectant liquid is injected into the bone beyond the canal. It should clear up when the liquid is cleared away slowly. Ask your dentist to remove the crown until the pain goes away completely. Also, get an x-ray done to see if the file is protruding out.

Strong antibiotics are also required.

Thank you doctor,

I have attached two x-rays.

Hello,

Welcome back to icliniq.com.

I have seen the x-rays (attachment removed to protect patient identity).

I think the pain will subside in a few more days. You should take antibiotics like Augmentin (Amoxicillin and Clavulanic acid) 625 mg thrice a day for a week, along with a painkiller. The broken file does not seem to be the cause of continuous pain.

Do not place the crown for now until the pain is there.
