nyuszisie,

Typically a round black radiographic area above a root canaled tooth indicates that the bacteria has proliferated beyond the tooth into the bone. The dark area is usually a cyst that has formed at the apex (root) of the tooth. This is not an unusual occurrence at all. So I really don't know why he would have told you that. I truly have no idea what he is talking about when he says an air bubble. You could have a sinus communication between the tooth and the sinus in which the bacteria has proliferated beyond the tooth into the sinus. That would also show as a black area above the tooth. But an air bubble??? I really don't know anything about that.

The fact that he can feel this "bump" in your mouth makes me lean towards the cyst possibility.

Based on extensive information that I have provided here on this site and that you could find if you were to search a little bit for it..... there is no denying that this root canaled tooth is not healthy. Bacteria has been residing in this tooth for many, many years and unfortunately it will travel beyond the tooth. I cannot tell you why your dentist told you he has never seen this before... perhaps you misunderstood him or he misspoke? I really don't know.

I wish I could offer you something more than I already have. But there really is no mystery here and I wish you could find the help that you need.

It's the upper jaw, above tooth #5, root canaled 20+ years ago. But he said he doesn't see anything to worry about, no infection. He said it can be felt in my mouth, where the gums and cheek meet as a little "bump". My sinuses and everything else looked ok.[/QUOTE]
