My sister and I are like you. We've both taken somewhat spotty care of our teeth over the years and never really had problems. I've never had a cavity, never had gingivitis. I do get plaque, but I just scrape it off with one of those dental picks. A long time ago, a dentist we had told our parents we had good mouth bacteria or something. I don't know how true this is and I don't put much credence in it, but interestingly enough, the only time in my life I had any kind of gum problems was when I was regularly kissing someone with constant tooth problems. It went away after we broke up and i haven't had problems since again. Again more just a little side note than anything scientific or would recommend basing decisions on.
