The dentist’s office in Harlan smelled like bubblegum polish and latex. It was a clean, bright smell, the kind that usually meant nothing worse than a small cavity or a stubborn baby tooth. I sat in the waiting room with Mason, watching him rub his thumb over the little plastic treasure chest he had picked from the bin. He wore his green dinosaur sweatshirt, the one with the sleeve cuff chewed thin from weeks of nervous habit. I had brought him in because he complained when he chewed his morning toast. Just a loose molar. Nothing to lose sleep over. I even had the insurance card with the bent corner tucked into my purse, along with a coupon for a fluoride treatment I had clipped from the Sunday paper.
