A new book, The Teeth Whitening Cure: A Holistic Guide to Bright Smiles and Better Health in a Toxic World by Lester Sawicki, DDS, was written in response to the potentially toxic effects of tooth-bleaching gels. According to Sawicki, "There is no safe way to whiten teeth with these kinds of products. They can cause extreme tooth sensitivity and mouth sores."
In the book, he proposes alternatives with ingredients that can be found and made in most kitchens. The book describes Sawicki’s method (which he says he arrived at after 10,000 hours of research) of using hydrogen peroxide, vitamins, minerals, herbs, and exercise to "detox the body, create a whiter smile, improve health and fitness, and boost energy levels."
