I had a abscessed tooth that was giving me fits. This is what worked for me. 2-3 oz. of very warm water, add 2 tablespoons of 10ppm colloidal silver and only 6 drops of DMSO. Swish this around your bad tooth. I try to keep it in my mouth about 2-3 minutes then spit it out. Keep doing this till you have used all the water mixture. Do this 2 times a day and in 2-3 days the infection and pain will be gone. It really worked for me.
