A dental file broke off in one of my canals 10 years ago and just found out about a year ago. There is still an infection underneath the file and though I'm not feeling any pain, am I better off leaving it alone or have it surgically romoved? Can having an infection cause other health issues? Is there more of a chance of the tooth fracturing by leaving the dental file or removing it? I'm leaning towards having it surgically removed because it's been wearing on me mentally knowing that there is a foreign object left in my mouth. I look forward to hearing from someone. Thank you.
