Thanks for taking the time to explain - that's very interesting.
For me though, it still begs the question: If infection in the mouth and teeth have such important consequences, why doesn't dentistry devote itself to treating infections rather than amputation as the first course?
Here's what happened to me. I went to a dentist because one of my teeth that a filling dropped out of was in big pain - it was obviously infected. Before I even saw the doctor the aggressive receptionist (probably his wife) told me I would need a root canal.
I asked how she would know that and she replied "because 99% of the time when patients have lots of pain in the tooth, that's the only way to treat it. You do want to save the tooth don't you?" I said I thought that a root canal meant killing the tooth - and she responded that other teeth would go bad if they don't do the root canal. Mind you nobody had even looked in my mouth at that point.
I finally got in to see the dentist and he looked in my mouth and said I'd need two root canals and lets discuss payment options. I asked him that since my filling was out and the root exposed if he couldn't put some kind of Antibiotic in there and seal it up with a temp filling while i think it over.
No, an Antibiotic wouldn't help, but he very reluctantly put the temp filling in. So I decided to go home and pull with oregano oil - but it was too bad I didn't apply oregano oil directly while the filling was still missing.
But after a very painful day, enough oregano oil must have been absorbed in the gums to kill the infection. I believe that was a couple years ago and both of my teeth have been painfree and back to normal ever since.
Certainly in the year 2009, Science and medicine has come up with many different delivery systems for Antibiotics and antibacterials that would work fine in the mouth and for teeth. Maybe even better than swishing antibacterial oils.
So why is dentistry still focused on killing teeth instead of killing infections as the first course of action? My guess is it would be very difficult to talk a patient into shelling $1000 out to simply topically or otherwise apply Antibiotics to an infection.
Much easier to justify putting out that kind of money for a painful four hour extraction. Must be our puritan upbringing..
