Georgia,
I have used CS with DMSO, oregano oil on cotton swabs and the godzilla for 
tooth infections and godzilla is the fastest and most effective of all.
Since time is of the essence make a 3 volt godzilla yourself. Get a CR-123, 3 
volt lithium battery. I would not use 6 volts. By itself it will provide too 
much current unless you do something to limit the the current such as use a 
resistor in line. (When I use 4.5 volts I need a 10K ohm resistor). Cut the 
ends off a cheap 2 wire extension cord. Strip the wires on each end of the 
cord. On one end of the cord wrap a small piece of cloth around one bare end of 
wire and tie the cloth in place with string. Do the same with the second wire 
at the same end of the cord. They need to be small enough to fit on each side 
of the infected tooth. On the other end of the cord, tape the bare part of the 
wires to each end of the battery. Wrap a heavy rubber band around the battery 
lengthwise so the rubber band holds the wires tight against the ends of the 
battery. If the battery or wire gets warm you have a short so quickly remove 
the wire from the battery and try again. 
Once you have done the above, wet both cloth ends and place one cloth covered 
wire on each side of the bad tooth. Every 5 to 10 minutes swap the cloth 
electrodes. Do this for a total of 20 minutes twice a day.
