smile and much more. But who would ever thought that teeth could have a significant role in helping deaf people hear again?

Doctors at Oklahoma University have developed a way to transmit sounds through the teeth, allowing those who are completely deaf in one ear to hear much better!

Dustin Brown is a patient who lost his hearing in one ear due to cancer, causing what doctors refer to as “single sided deafness.” Instead of surgery, Brown opted for a system in a dental retainer-like device that was placed over the lower molarsand a small microphone put in his deaf ear. This then transmits the sound though his teeth into his unaffected ear.

Dr Betty Tsai, a physician at Oklahoma University said, ”
Bone is actually a very good conductor for sound. In fact, sound travels more efficiently through bone than it does through air.”

Dustin and his wife say this technology has not only helped him hear again, but it has helped them communicate. Jennifer Brown said it is a lot less frustrating now. Before he would have to say, “huh” or “what.” It’s so much better for us. Dustin said, “The most difference I’ve seen is when I’m driving and I can actually hear what my wife is saying now.

Not only can Dustin hear better, but just for saying that he wins Husband of the Year!!
