Hello,
During mechanical enlargement of my root canals, my dentist broke the tip of an instrument, which has now remained in the tooth. He said he would simply leave it in the tooth. Since I did not want this, I asked about possible solutions and received a referral to the dental clinic. I am now waiting for an examination there. What is your opinion regarding treatment in such a case?
Kind regards.

Dear Sir/Madam!

Fracture of an instrument in a root canal is a classic complication of root canal treatment. Removing the instrument can be a complicated and difficult procedure that can ultimately also cause additional complications in the affected tooth. If the tooth does not cause symptoms and follow-up X-rays do not show deterioration of the condition (periapical resorptions), the fractured fragment can be left in the tooth, as it represents only part of an apparently good root canal filling. Otherwise (symptoms, X-ray shows periapical changes), the instrument would need to be removed, since theoretically it could represent the cause of the listed complications.

Have a nice day!
