Commonly seen in factories, on farms, and in other noisy arenas today, noise cancelling headphones have proven very successful at protecting the hearing of the individuals who don them, while still allowing them to communicate with others.

A new device that is sure to have a dramatic effect on the dental field is using similar technology to block out the dreaded sound of the dental drill.

This tool used by dentists when removing damaged areas of tooth before filling the cavity to protect it from further decay is often the leading cause of anxiety in patients. Much of the fear stems from the high pitched squeal that the drill gives off as it is operated.

Researchers believe that if the noise was no longer an issue, patients would be better able to relax and, therefore, more likely to consent to recommended treatment.

These new, specially designed headphones will make it possible for patients to plug into their handheld devices, so they can enjoy their favorite music. In the meantime, the noise of the drill would intentionally be drowned out, but the patient would still have the ability to hear the dentist and other staff members.

Professor Brian Millar of King’s College was the first to develop this idea. Though similar to other noise-cancelling ear devices, these would require an amplified ability to address the unusually high pitch of the dental drill.

Though not currently available (the college is seeking investors), it is thought that once developed, the headphones would be very cost effective for dental offices to invest in, making it possible for patients to enjoy them without it being tacked onto their bills.
