This is what literally saved my life and can restore your health as well:
1. Get rid of this root canal
2. Chelate heavy metals on the Cutler protocol. No other method I ever tried had the same effect http://www.noamalgam.com
3. Eat Rosedale ketogenic
By detoxing improperly, you merely redistributed the toxins. This is why you have been diagnosed with so chronic illnesses afterwards. You re-poisoned yourself, not "detoxed".
The ketogenic diet is the right hing to do; one thing to be aware of, though, is the fact that you must limit your protein intake to less than 1g of protein per 1kg of lean body mass per day or you'll poison yourself with ammonia and glucose (excess protein converts to glucose and kicks you out of your ketogenic state, reverting to glucose metabolism in the presence of ammonia, the worst diet to be on!).
Get rid of that root canal. As someone pointed out, dentists can't see anything on their bloody Xrays, they only pretend to. I had an inflammation that ate away half my face, and they maintained there was nothing, until an oral surgeon got his hands on it, and half my face gushed out of the cavity to his total bewilderment (he was so stunned, he hadn't see it coming, that I ended up not having to pay for the surgery).
I had about 12 root canal procedures over the years (repeat root canals in 6 teeth), until I finally got rid of all disease-causing dead teeth (in my 20s and 30s, not in my 80s, mind you!). All of them. I only wish I had done this sooner rather than later.
On my advice, my mom had a root canal pulled a year ago. For the first time in 30yrs, she did not get the flu this season (she used to have a cold all the time and severe viral infections every couple of weeks). Now my mom listens to everything I say...
