Also look at Rami Nagel's sites. He has a book called "Cure Tooth Decay" based on weston price research that pulls it all together for the teeth.
He's been very generous with putting all his information onto websites so you could basically get the jest of it without spending money on the book. His videos are excellent.
I had a hyperthyroid problem about a month ago that pulled the calcium out of my two weak teeth and they hurt like crazy. I was using magnesium to calm my nerves and that really made it worse. Bad enough I thought I had an abcess.
I started upping my butter (Kerry Gold), raw dairy and bone meal and oil pulling. and My teeth have recovered nicely. The pain is completely gone. I went to my dentist last week to have both teeth looked at and he was stunned at how good my gums are for someone mid-50s.
I think if you try what's in Rami Nagel's book and on his sites you might be able to control the pain long enough to allow you to try a few things.
