I will not be arguing with you as you clearly made up your mind and think I am a loony. But at least inform and educate yourself before you start using something as dangerous as alcoholic mouthwash from a supermarket shelf.
We all agree with the dentists, you need to keep your oral cavity as pure and clean as possible. All disease starts there and the whole digestive tract. But there are many ways to keep your mouth clean and some of them are superior to others. Not only they are more effective but also less dangerous for the overall health. keeping your mouth clean at the price of getting a cancer is not my chosen action.
And one more thing, many people here experienced improvement and relief from periodontal disease. More than the best dental care can offer - the best they can do is slow it down.
