In 1984, I may have had almost the worst overbite on the planet, but darn if my teeth weren't tough. After 32 years, I still don't have a cavity. So that's why I was so confused at the pediatric dentist today. My precious 3 year old girl needs root canals, caps and fillings, and she'll have to be put under general anaesthetic for the whole procedure. The dentist thinks it's from nursing Ana at night and letting her fall asleep with a breast in her mouth. As comforting as it was for her, it seems it's done in her teeth.
