Goodbye, Perfect Teeth

My once perfect, healthy, cavity-free teeth have succumbed to the inevitable: tooth decay. I suspected that this day would come sooner or later, and it has. The dentist's theory is that I produced too much acid in my mouth during my pregnancy and it ate away at the enamel on my back left molar. So this morning I'm getting my very first cavity filled. Such a bummer! Still, I am grateful that it is just one cavity and that I didn't develop any more.
