There was this stuff made by thus company Oragenics or something like that. It was a swab of modified bacteria that would replace the bacteria in your mouth. The bacteria in your mouth eat and then crap acid that decays your teeth. This new bacteria did not crap acid. So you wouldn’t get cavities. They had a daily pill but they made this swab that would last forever.
