The Wonders of Large Intestine 6

So, a few times this year, I've been presented with cases of simple toothache. Normally, my response has been, "Have you seen your dentist?" Of course, with this economy, dental plans are even scarcer than regular health coverage. For emergencies, however, people still go to the dentist but are often in pain before they get the problem resolved.
Friends who know me know that I love to use luo-points whenever possible, because they do a lot, but the Large Intestine luo, Pianli, has proven itself a marvel in controlling the pain from tooth decay. Naturally, it can't stop the decay, but it can ease the suffering. One person I used it on asked me, "Is it supposed to work that instantaneously?"
This supports the chapter from the nei jing about luo pathologies, wherein it states that the luo-channel excess indication for Pianli L.I. 6 is tooth decay and deafness, while luo-channel deficiency signs are cold teeth and obstruction of the diaphragm.
I should add that whether deficiency or excess, one should probably refrain from activities that strip away the enamel from the teeth. Flossing and brushing are good, sensible actions, but over-brushing with harsh toothpastes can damage the dentin. Similarly, an excess of coffee can undermine the teeth by leeching away minerals from the system. In TCM terms, coffee's hot, descending and yin stealing nature harm the Kidneys, of which the teeth are the odds and ends. Too bad I love the stuff.
