So when I get a back-rub, different spots on my back stimulate feelings in different teeth. Is this a common experience?

That being the case, do you think that teeth are a nervous-system diagnostic indicator or something? Like there is a Kidneys tooth, and digestive teeth, and reproductive teeth, etc, and that you can get a sense of your internal chemistry by way of tooth-sensations?

I had this idea when looking at my cats' whiskers, and thought, "wow there are so many, and they are all sensitive and lead directly to the brain, so, when the body is affected, it must register in the whiskers." Then I thought about my own face and the closest thing I could compare that to was my back-rub tooth tingle sensation.

My friend says that chinese nerve meridian stuff addresses this, but I am unfamiliar with anything about that discipline. Anyone know about that stuff?
