Kelly J. Baker My six-year old’s smile is missing yet another tooth. She lost her second incisor three weekends ago, and all that remains is a gaping hole where it used to reside. Since the start of Kindergarten, she’s lost four teeth in total. Her adult teeth are crowding into the small gaps left behind. The teeth that she fiercely cut as a baby are disappearing one by one, and now, she spends much time wiggling her loose teeth to determine whether they are ready to pull out. Wiggle, creak, wiggle, creak, wiggle, creak. Eventually, she cajoles me into offering a second opinion on a tooth’s looseness.
