Bex,
This might help, I dont' know how deep the gangrene is? But I would think just by injecting Hydrogen Peroxide between the gums and your teeth it should definitely reach the area. Dead nerves reach pretty far down.

1) Order a dental syringe for treating gums that can inject Hydrogen Peroxide to the area. (Simple device to inject H.P. between the gums and the teeth.) Hydrogen peroxide provides oxygen and high amounts of antiseptics to the area.

2) Swish your mouth 3 times a day with pure water and sea salt. (Not table salt.) This Person was able to remineralize and grow back enamel where cavities used to be.

3) NEVER use toothpaste. They all have glycerin in them, which forms a coat on the teeth, and therefore the cells in the teeth cannot do their job.

4) Buy aloe vera gel and brush with that. The aloe vera plant has amazing medicinal properties and antiseptic properties. (Make sure you angle your toothbrush 45 degrees to get up between the gums.)

5) If your tap water is flouridated, buy a flouride filter IMMEDIATELY. Flouride is an industrial waste, and actually weakens the teeth. (But it's good for the dentists. Makes sure to bring back repeat business !)

I hate to say this but the dental community is almost the same as the doctors. Using methods that make them money, but rarely help the patient.

You're right if your teeth have infections the whole body suffers. Try what I mentioned and if you can get balancing herbs for the rest of the body from a Chinese doctors diagnosis, you'll see a big difference.
