Q.
lower molar gets root canal 2 years ago. x-ray at time shows suspicious small shaded area beneath the root that may be infection. so no crown is put on in case the infection develops and removal is req’d. Now, infection starts to erupt from gum surrounding the tooth. Dentist suspects fractured tooth has been cause but not seen on xray. new xray now suggests infection spreading in bone. Is there really any option but removal?
