Believe it or not, now you can listen to music through your teeth! The device, called Play-A-Grill, works similarly to how a hearing aid helps a hearing impaired person. It is mounted to a retainer and controlled with the tongue.
Aisen Caro Chacin, the inventor of this innovative product, explains, "There is a motor connected to the output socket of the MP3 player that vibrates to the frequency of the sound. When bitten, your teeth oscillate to the same frequency. Because they are embedded in the jaw, close to your ears, the inner ear bones also oscillate, allowing the nerves to process this vibration as sound information."
Although it may seem like a fun new product, many dentists are advising against using it. They fear biting down on something such as this for extended periods of time and vibrations throughout the jaw could disrupt the alignment of teeth.
