ABC News Health: New Technology Could Silence the Shriek of a Dental Drill

If you cringe at the high-pitched squeal of a dentist's drill, you're not alone. Studies have shown it's that very sound that makes people anxious about going to the dentist.

"It's been demonstrated that people's blood pressures rise as soon as they hear the sound, even if they're not sitting in the chair yet," said Dr. Mark Wolff, professor and chair of the Department of Cariology and Comprehensive Care at the New York University College of Dentistry.
