when he examined me he did xrays which showed bone loss around 1 1/2 of the teeth and also that the nerve to 1 tooth had died. my question is, could the bone loss
be due to
a nasty sinus infection or chronic sinusitis, or to
a small cavity which was filled 35 years ago with a gold filling which was replaced with a normal filling 8 years ago. also, if the nerve is dead, even though the infection seems to have cleared up, why is the tooth still aching a little?
