I did hear something weird yesterday.
Oil pulling, You take some tasty veg oil, like avocado, or coconut and swish in your mouth for 15 minutes. Repeat daily, (use fresh oil)
We know that mouth infections can go the rest of the body. Some heart disease, for example is linked to bad gum hygiene. And we can't workout with a head cold, It can lead to other infections as you force it around your system.
Oil pulling is suppose to be for the working it the other way, All the bacteria will gravitate into the oil for a rich meal. <spit>
Then after a few weeks and the mouth clears up. the bacterial migration begins from the rest of the body, (or the placebo effect, who care?)
Worth a try, maybe.
