Hi cinnamongym,

Infections in the upper posterior teeth can spread to the sinus. In fact, that is one of the major risks associated with doing root canal therapy and/or apicoectomies in these teeth.

When you get a chance... please send us a note about how things went today at the dentist.

drs.QUOTE=cinnamongym;888557]I'm heading to the dentist later today, and am interested to see what he has to say. I don't mind getting the tooth extracted, it's just frustrating after paying for 2 root canals now.

I just have one more question though, around the same time my infection started to hurt I noticed a lot of blood in my nose when I blow it. It never bleeds like a nosebleed, but there's always dried blood in there. Could that be related?[/QUOTE]
