CS>silver plating in mouth

Thu, 13 Aug 2015 10:34:29 -0700 

I have some gum erosion in my mouth which leaves a bit of tooth root exposed.  
When I take eis on a regular basis the exposed tooth root turns black as if it 
was plating.  I wonder what is happening to other areas of my body where the 
eis lands.  
Any thoughts?Thanks.PT
