It appears I need a root canal.
It's the middle molar on the right side.
It's left side counterpart was the molar from hell and is gone now.
The rest of my teeth have always been very happy.
If I was techno-savvy I'd scan the x-ray and post it.
(Since Dr. Lang is sending me to a specialist he gave me the x-ray to take with.)
I'll keep you posted.
