if you want the simple answer -- there are bacteria that occur normally in the oral cavity. they group together to form plaque, which attaches to tooth surface. when you eat sugar, you're feeding this bacteria -- they metabolize the sugar and produce lactic acid as a byproduct. these bacteria basically eat away at your teeth. the way to prevent this is regular brushing/flossing to ensure removal of as much plaque, etc as possible, and regular professional cleanings to ensure complete removal of plaque calculus.
(can you tell what i'm in school for yet? lol...sorry for the rant, just finishing finals and it's all i can talk about in any sort of coherent manner)
