RE: biden dentures. found this picture while digging around on it. looking at tooth shade and the obvious undercut shadow on the right hand side (his left) first premolar and applying my years working in my father's dental lab, i would venture that biden wears lower partial dental appliance that consists of 4-5 false teeth. further if we look gum recession, they are mounted from behind on a framework that does not have an acrylic saddle, a method used to make them appear more natural. also, that dude is jacked up on something the way he is jawing.
