I recently started researching the above and was horrified at the health risks of root canals. I had one in 06 (the last time i saw a dentist as i am phobic and that was as much as i could take)
Pre 06 i was super fit and healthy, trained and worked out daily - would think nothing of running 16km, etc etc. Was energetic and happy
After root canal in 06:
Developed crippling gastric symptoms (now known to be coeliac and IBS), anxiety
2007: enormous fibroid removed but not before i needed 3 blood transfusions due to severe anaemia. Personality changed to extremely anxious all the time
2007 onwards, worsening fatigue which eventually nearly cost me my job (2012), chronic hairloss and premature aging of skin all over body.
2008: hypoglycaemia, now much worse
2012: pernicious anaemia, chronic neutropaenia - thus frequent infections. Vertigo for best part of a year, severe fatigue
This is not an exhaustive list - i struggle to remember everything
So: decide i need to overcome my dental phobia. See a holistic dentist who says highly likely i have mercury poisoning (loads of mercury fillings from childhood) and that the asymptomatic root canal must come out as it is almost certainly infected
Won't bore you with the melodramatics but managed to have tooth extracted today. Sure enough, there was a bad infection (probably been there for years) and the root canal filling had actually penetrated the bottom the canal and come out the other side, so a steady flow of bacteria and toxins into my system.
I am CONVINCED i will feel the health benefits very soon. Next step - 5 sessions to remove the mercury
