Ooohhh, Hi everyone! I'm back. What were we...oh yeah...bugs...I think we were looking at bugs last time and I was trying to convince you bugs, by themselves, lack the ability to cause a cavity. I'm not sure if any of you went there with me but it's true. So...now we're looking at sugar. As is the case with bugs, sugar lacks the ability to form a cavity by itself. There’s no inherent property in sugar that gives it the ability to eat holes in teeth. Have studies been done on this you might ask? Yeah - what do they suggest? Dogs raised without sugar in their diet enjoy being cavity free. Reports suggest they are also very sad. Sad because of the "no sugar" thing, but cavity free none the less. So...dogs raised without bugs, eating all kinds of sugar, and dogs eating anything but sugar go cavity free. Cavity free sounds good, but we're trying to discover how cavities are formed. O.K., so how do we get a cavity? I think we'll answer it next time. Until then...
