Haha, I hear ya. I've talked to some people who have done it though and I do see a visible difference with their teeth. I've had inflamed gums for a number of years now, despite flossing and brushing due to effects from histamine intolerance.
I think the toxin stuff is a bit hooey, but bacteria in the mouth has been proven to impact heart disease. The problem with traditional mouthwash is that it kills ALL bacteria, even the good stuff (same reason that the Red Cross no longer recommends peroxide as a means of cleaning out wounds). I hate natural mouthwashes and don't think they are especially effective. I also do think that inflammation is a proven cause for many different types of disease in the body, so any way that I can reduce that is fairly important, as I've lost a decade to weird health stuff already and inflammation has also made it difficult to lose weight.
I've been looking into a lot of other factors, from emotional processing and habits to sugar intake, etc etc, so am just trying to do what I can to tip the balances in my favour. One friend who easily goes into anaphylactic shock from soy has said brushing, flossing and drinking copious amounts of water help a lot when she's having trouble, so I think there is some kind of mouth connection to how the rest of the body is impacted.
I'm having growing sensitivities to everything foodwise and I've seen how out of hand that gets if its ignored - one of our friend's had to live two years like a bubble boy as her immune system was shot. She couldn't even handle paper unless it was under glass, and her husband had to change from his street clothes to come into their apartment. Walking and vitamin C injections were big factors in her recovery.
