Dr John Kelly's office is near Devon and Central, and he focuses on what he calls the art and design of the mouth. So although he does general dentistry, he also does much more. They even talked about it on ESPN's "Monday Night Football.". "It relaxes the muscles of the head, neck and face. And from that bite position we create the mouthpiece.". But can this actually make you a better athlete? Some of the Bears are beginning to wear the PPM.
"I just needed to find an additional edge and so far it's helped me with endurance, strength and stopping injuries.". "The pro model is generally around $2,000," Kelly related. But for the newbies trimmed down PPM goes for roughly $1,200.
