That is the sound that I love to hear when I pull one of my student's teeth. I LOVE to pull teeth. I think I missed my calling as a pediatric dentist. One of my kids asked me to pull his front tooth today...imagine me grinning with delight while singing "I'll Be Your Dentist" from Little Shop of Horrors. Don't worry, I only pull really wiggly ones...clad in latex gloves of course!
