Q. Next to the last molar top left of my mouth has had a root canal & crown (lont time ago) with re-treatment of root canal about 5 years ago. After infection and appt was told the root is cracked (11/08). I hesitate extraction and subsequent implant for financial reasons. It has not become re-infected to my knowledge. I have had a headache for 3 weeks. Could the tooth issue cause this? If I have it extracted (partically covered by insurance) how long to I have to perform a bridge or implant? Are their other options? Again cost is a huge factor. Wish it was the back tooth – I’d have it pulled without anything else, however this effects my smile.
