1-800-220-3741 is the number given me by the Dr. Clark Association with the products I received from ordering online at drclark.com.
I have been using the HCL drops to purify my milk (1 drop per cup) for the last four days. I was very pleased with their purity and with the results, until last night I noticed the tip of my left front tooth, which was smooth, is now rough and ridged. Also, the rest of my teeth are more sensitive. Perhaps if I had brushed my teeth immediately, or even rinsed well, my teeth would be fine. Any hints on how to rebuild enamel?
