Just found something from your original WP link. Was considering extraction (mine is in a molar), but appears equally detrimental. See snippet from the WP link below:
Cavitations are the next big problem that result from dental procedures. Cavitations are areas of unhealed bone left over after a tooth extraction (see Figure 9).
Dentists are generally taught to remove a tooth and leave the periodontal ligament in the socket, a procedure which would be like delivering a baby and leaving the placenta in the uterus.
These socket areas with the ligament left in place rarely heal. After tooth removal, a cap of about 2 millimeters (one sixteenth of an inch) covers the extraction site, leaving a hole the size of the root of the tooth behind. In records of five thousand surgical debridements (cleaning) of cavitations, only two were found to be healed.14 When the periodontal ligament is left in the bone, the body senses that the tooth is still there, and the order for healing is canceled. These holes are lined with many of the same bacteria found in root canal
sockets, but actually more different species. Whereas root canal
teeth contain up to fifty-three different species of bacteria, cavitations yield up to eighty-two of the eighty-three we test for.
Of the five most frequently present bacteria found in cavitations, three affect the heart, two the nervous system and one the kidneys and lungs. They are as follows:
Streptococcus mutans (occurrence 63 percent of the samples), affects the nervous system, can cause pneumonia, sinusitis, otitis media and meningitis. It has also been blamed for causing dental decay in teeth, but this may be more the result of the fluid flow pulling bacteria into the tooth than actual active invasion by the bacteria.2
Porphyromonas gingivalis (occurring in 51 percent of the samples), damages the kidney, alters integrity of endothelial lining of blood vessels, and induces foam cells from macrophages, contributing to atherogenesis. It contains proteases that lyse red blood cells and extract nutrients (primarily iron) from the red blood cells. This action is called porin forming, which can destroy red blood cells rapidly. (By the way, P. gingivalis can both up and down regulate about five hundred different proteins critical to maintaining our normal biochemical actions.)
Candida albicans (present in 44 percent of the samples), in its yeast form is beneficial in the process of demethylation of methyl-mercury as well as its ability to destroy pathogenic bacteria in the intestinal tract. When converted into the fungal form by a shift in pH in the digestive system, candida can penetrate the intestinal wall, leaving microscopic holes that allow toxins, undigested food particles, bacteria and other yeasts to enter the blood stream. This condition is sometimes referred to as Leaky Gut Syndrome, which can lead to environmental intolerances.
Prevotella intermedia (occurrence rate of 44 percent) has as its primary concern coronary heart disease (CHD). P. intermedia invades human coronary artery endothelial cells and smooth muscle cells. It is generally located in atheromatous plaques. Cellular invasion of cardiac muscle is central to the infective process.11
