This is a classic response from some one who has worked with dentists. I am sorry to say, but my friend, you have been brain washed. root canals ALL fail. They are a breeding ground for anerobic bacteria. Read some books about it, written by actual dentists that tell the truth about this procedure.
You say :
"Having said this is the best alternative treatment removing the teeth? I have participated in studies where they evaluated the effects of tooth removal, in truth this is were your nutritionist alarms should be buzzing the loudest, Major TMJ effect are caused by tooth loss, dietary problems from constipation to stomach ulcers, Migraines, ear infections, vision problems the list goes on, but probably the most disturbing is the fact that the removal of a tooth causes an opening for future infections."
I say of course the removal of a tooth causes an opening for future infection. It is because the dentist does NOT take out the periodontal ligament, nor does the dentist clean out the place where the tooth was removed. Even medical doctors clean out wounds....sadly enough dentists DO NOT and that is what causes cavitations.
