New Device Set to Combat Fear of the Dentist's Drill

An innovative device which cancels out the noise of the dental drill could spell the end of people's anxiety about trips to the dentist, according to experts at King's College London, Brunel University and London South Bank University, who pioneered the invention.

It is widely known that the sound of the dental drill is the prime cause of anxiety about dental treatment, and some patients avoid trips to the dentist because of it. This new device could help address people's fears and encourage them to seek the oral healthcare treatment they need.

The prototype device works in a similar way to noise-cancelling headphones but is designed to deal with the very high pitch of the dental drill. Patients would simply unplug their headphones, plug the device into their MP3 player or mobile phone, and then plug the headphones into the device, allowing them to listen to their own music while completely blocking out the unpleasant sound of the drill and suction equipment. The patient can still hear the dentist and other members of the dental team speaking to them but other unwanted sounds are filtered out by the device.
