It doesn't touch the gums.  This works from passing through the cheeks.  The
device is used only on the outside of the skin.  So--that's why I don't know
if I actually need something that will conduct electricity, or if just
keeping the skin moist will conduct it.  

When I use my Godzilla, all you need to do is keep the electrodes wet.  This
wets the skin and allows passage of the electricity--but then I am also
using 2 separate electrodes, passing electricity back and forth between them


This is an ultrasonic device, simply put against the skin--no 'separate'
electrodes.  So I don't know if it still ONLY needs something to keep the
skin moist, or if there is actually something in a conductive gel that 
intensifies' the current.  Hence my question about the gel.  I'm thinking it
may be like what I've heard people that use TENS units use--a conductive gel
  

Perhaps I'll go ask on the electric list--someone there may know as there
may be more people there using such devices as I'm talking about.

What is the purpose of the gel?
 
I persume it is to provide a medium to conduct the ultrasonic waves into the
gums, much like the gel they use for baby ultrasounds.  I doubt there is any
reason to have it actually conduct electricity. 
 
My recomendation would be to try your own gel.
