Dr. Mark, Thank you! Your products have helped me so much. The one upper molar pain is going away, that is, around a crown where the gum was receding slightly. That area has hurt for many years and the dentist always thought it might be sinus/allergies, but I have truly been helped with the use of Calcium Therapy. Also, I have a chipping away on a front bottom tooth at the base that is actually filling back in with the products of yours that I use every day. Sincerely, PW in Indiana
