A new device will be able to block out the high pitched whine of dentist drills may soon make a visit to the dentist more tolerable. The device will consist of a headset that will contain a microphone and a microchip, which will use adaptive filtering to block certain sound waves, even when shifting frequencies. The selective blocking of the sound waves will allow music from the dentist or a mobile device to reach the patient's ears, while eliminating the sound of the drill.

The dentist office may have gotten less scary with the new plasma "brush", which can clean and prep cavities painlessly for filling. The brush will clean a cavity in under minute. The brush will use ions to kill bacteria and release the plaque from the tooth while also prepping the surface for treatment. The plasma-assisted filling may able be up to 60 percent stronger than conventional fillings.
