paracetamol is the one I understood to have a particularly unhelpful effect on glutathione, I dont remember the mechanism. But when you are in acute dental pain, none of that matters. The DF's will probably make you constipated if you take them for anytime, so take a spoonful of linseeds soaked for eight hours in a glass of water once a day to get the bowels back online. This I discovered when nursing my father who was on them and other opiates when he had lung cancer. Longer term dental pain I am also treating with End Pain Now by fatigued to fantasitc, some people recommned pyconogenol, thats spelt wrong, ME brain, and I'm starting curcumin. Amoxicillian may have a limited impact on anerobic pathogens, I have also had flagyl and the one that really kicked arse - clindamycin. They all disturb the gut flora, there is a price to pay! But when you are in that pain, I know you just need it to go away. I looked at the Munroe Hall clinic website -I wish to god I had seen it a year ago. But I'm glad you posted it, if I can afford it, I am going to check out the cavitation thing. Good luck with the pain. When its acute you can also try pressing on some of the accupuncture points - it does at least distract you - like squeezing the tops of your thumbs firmly or pressing into the fold of skin between the thumb and first fingers. There are a lot of good sites online with accupressure points on.
