Hi doctor,I have done a root canal before few years. But it fell off, and nothing has been there for a few years. This morning, when I woke up, I saw a black pointy substance sticking out on my gum. What is it?
Hi, Welcome to Chat Doctor forum. I have gone through the attachment (attachment removed to protect patient identity). On looking your tooth and after going through your complaint, there is a retained root piece. It is left behind there. There is nothing to worry. You need to extract it soon from your dentist. Root canal treatment generally fails when the tooth is not capped. Since it has fallen on its own, the top portion of the tooth has come off leaving the root stump. In some instances, you can see it after a long time due to gum recession.
