Price was concerned about the pathological bacteria found in nearly all root canal teeth of that time. He was able to transfer diseases harbored by humans from their extracted root canal teeth into rabbits by inserting a fragment of a root canal root under the skin in the belly area of a test rabbit. He found that root canal fragments from a person who had suffered a heart attack, when implanted into a rabbit, would cause a heart attack in the rabbit within a few weeks. Transference of heart disease could be accomplished 100 percent of the time. Some diseases transferred only 88 percent of the time, but the handwriting was on the wall.

Dr. Price discovered that root canals had within them bacteria capable of producing many diseases. They had no place in the body. Which is more important? The life of the tooth or the life of the patient? This is still the primary argument facing us today
