My Wall of Fire: A Story of Recovery from Dental Toxins is a nonfiction medical memoir by author Mary T. Kroening that shares her inspiring journey from chronic illness and pain to ultimate healing.

With the support of her husband and eight children, Mary embarked on a journey to research her ongoing pain and toxin infection. Her research led her to a team of highly skilled oral surgeons that helped cleanse her body of its ongoing mercury poisoning and other toxic infections. Using a healthy eating regimen of organic food and mineral supplements, Mary was able to achieve lasting health. Through each trial, Mary relied on her faith, trusting in God's goodness.
