At a routine teeth cleaning was informed that one of three roots of an upper molar must be removed(it extends into a sinus and a small pus pocket was found on X-Ray-no problem noted by me-dentist doesn't know why it formed) I thought maybe a EENT might just do a lavage of the sinus- but nooooo such luck. Then the news was when the root goes I'll be doomed to a root canal-UGH (all the horror stories heard zipped though my mind) My question to all is: Does anyone know of a dental Bulletin Board? and/or can give some information. I have read some sites re:root canals now a double UGH UGH. The tooth is capped already! Was informed the root canal can be done though the cap.
