Many have read my page on fasting and you need to also if you want to fast since there are dangers. Here is
my other page on it with a personal experience with tooth and gum problem and fasting. You can learn from Weston Price mistakes. He suggests eating meat and he killed his son.
He gave his son a root canal and they did not have antibiotics and his son died. If he would have known about fasting, he could have saved his son's life. But how could he know about it? The bible only has 74 references to fastng.
But fasting releases a swarm of hungry killer T cells. Now if you put some people in front of some lions that just ate, then what would they do. They would do nothing. Now put some people in front of some hungry lions and they will eat them. So fasting causes all the resources that you put into stuffing your face with food and eats all this bacteria and nasty stuff.
So you need to do the water fast with pure water so you cannot make any choices since you will choose the wrong stuff. Now let us get this clear. Your body did not cause this gum disease and all your physical problems. You did. So by fasting you let your body clean up the misatkes you made.
It is like Hell's Kitchen. Chef Ramsey comes into save a failing restaurant that is during everything wrong. He is the expert at making the best restaurants. He starts to tell them what they are doing wrong and they start to call him nuts and think that his advice is stupid. So your body is the leading expert in the world on healing itself. You are the one making it sick.
So when fasting on water you give all your control over to your body. Also see first page of my fasting page. How long do you fast for? That is simple. Until you are done. So my advice is find a fasting doctor (see site above) and let him tell you what to do and fast for as long as he says. This one guy could walk on water, heal the sick and bring the dead back to life and yet he fasted for 40 days but I forgot his name.
More specifically your dental and gum problems were caused by you eating. So the cure for them is to stop eating.
