This link was sent to me by a good friend concerning safe Root Canals.
It is suggested that you print this and take it to the Dentist you
want to do your root canal and leave it with him to read and after he
reads it and talks to you then you can decide on having him do the
root canal. If you just walk in on the day of your root canal
appointment and hand it to him then he probably would not have the
proper material on hand to do the root canal correctly. You would
have to give him a little bit of time to read and study the IAOMT
document and then he could get the material in a couple of days.
