A Palm Beach County, Florida, dentist named Dr. Joe has invented a device which vibrates and can be placed in the mouth to protect dentures, caps, fillings, etc. He dubs the invention the "Blowguard" and older swingers love it.
Dr. Joe got the idea when a female patient complained of denture issues when she performed oral sex on a male partner who she didn't want to know she had false teeth. He gave her a night guard to cover the dentures and that inspired this device.
According to Dr. Joe: "This is a unique, revolutionary product." He tested it with his wife before placing it on the market.
