Congested liver = not enough bile = not enough calcium uptake into the body = the body takes the calcium it needs from the teeth first then the bones.
I lost part of my lower right jaw before I got things squared away, and it hurt. Its all filled in now but when it was happening it was a problem.
Biles the key. Keep working on your liver, Once the bile is getting to the intestines in enough volumn the calcium uptake happens immediately and it doesn't take long at all to reestablish normal calcium levels thus the calcium loss in the teeth stops. But it may already be too late to save the tooth. And if there's infection behind the tooth it'll have to come out. Sorry.
