In periodontitis or pyorrhea, for instance, the gums are so irritated by bacteria that deep pockets of pus form between teeth, causing them to loosen and eventually fall out. Because this condition is usually painless, it's often ignored until it's too late. If the patient has pyorrhea and his teeth are loose enough, you can pull them with your bare hands. Since the people who visit psychic dentists are usually not examined beforehand, most of them probably have pyorrhea or loose teeth to begin with. That makes it easier for the healer to do his job.
Some healers use small screwdrivers to remove teeth.
These are carefully hidden from patients who are instructed to close their eyes during the session. Many die from tetanus that way. Once I had a patient who was suffering from severe bleeding. When I examined him, three of his molars were missing, including fragments of bone where they were attached. Obviously, the patient had visited a psychic dentist who removed these with crude instruments.
