Been doing this for years and have nearly perfect teeth due to it, flossing, and non alcohol based anti-gingivitis/anti-plaque mouth washing.
Also, people who think fluoride is bad for you or think it's not effective for teeth are exactly the kind of people I'm terrified of paying in the context of developing software. I really wish people would wear their love of homeopathy, and other psudo-scientific bullshit more clearly so they can be more easily avoided.
