Boo!

I went to the dentist this morning and they said they found a small cavity on my back molar. I was just in for my normal cleaning and check up when they found it. I guess the only good thing is that they said it was still quite small, which makes sense since I've not had any discomfort or anything. I don't know how it happened, since its not like I neglect my teeth or anything. I go back in a week to get it filled, WHICH I AM NOT LOOKING FORWARD TO.
