Blue light instead of a toothbrush?

If elementary school taught us one thing, it's that the toothbrush is our most valued weapon in the harried battle of good and evil that goes on in our mouths daily. Oh, and flossing. And mouthwash. And chewing gum. So it's no wonder scientists were motivated to discover that blue light coming off a halogen lamp is highly effective at killing gingivalis and prevotella intermedia in lingua, and without harming the "good bacteria" up in there. The money quote,
however, is slightly more compelling: "We think it will be particularly beneficial to those who don't like using a toothbrush." Yeah, but how else would we get that minty fresh feeling of cleanliness in the mornings? And what would happen to Sonicare and Tom up in Maine?
