bone loss and sinusitis

I recently went to the dentist with a slightly swollen and sore gum behind my 2 front teeth he diagnosed gingivitis and presribed antibiotics which relieved the swelling. 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? I am to see a periodontist in a week but it is worrying me sick wondering what the cause of this could be. Hpoe you can help

The bone loss is not caused by any sinusitis. If you have a dead nerve then root canal therapy is indicated, even if you have no discomfort.I think the periodontist will give you an indication of how serious the bone loss is and the proper treatment.
