Second Look (a project of DAMS, Inc.) is a national, educational non-profit initiative. We are concerned with the science and politics of public policies based on "acceptable" levels of risk that result in "low-level" toxic contamination with possible long-term health and environmental damage. (Please see About SL for a more detailed explanation of who we are.)

Second Look has always been concerned with the ubiquitous but "invisible" contamination by fluorides and fluorine compounds from all sources, and the resulting toxicity in humans and the environment.

We are proud of our huge Bibliography of Scientific Literature on Fluoride, through which one can access abstracts for most of the references, and whole papers or excerpts for many. Virtually all of our listings are peer-reviewed articles from mainstream medical, dental, and scientific journals worldwide, and most offer legitimate reason for concern regarding the health effects of fluoride toxicity.

One area of Second Look’s concern has been the public policy of water fluoridation, its health and environmental impacts, and its complexity as a social and ethical issue. provides scientifically oriented information representing all sides of the fluoridation and oral health policy related issues, from the best sources available. Read, compare, and decide for yourselves.

Do you think you may be fluoride poisoned? We also provide scientific and medical information on fluoride poisoning and related health effects in individuals. In recent years, we have been concentrating efforts on our developing program, The Fluoride Toxicity Research Collaborative (FTRC). This unique program seeks to help individuals suffering from fluoride illness, both chronic and acute, while engaging in research projects to make that end more feasible. Go to the FTRC WebCenter for more information about fluoride poisoning and suggestions for how you can help yourself.

We are currently preparing to publish our first book on fluoride illness, which is being written for those afflicted with fluoride poisoning. We will announce on this website when this book is ready and how to obtain copies. We also have in progress a book on fluoride poisoning in animals.

We have started a very special FTRC project: an online listing of fluorinated pharmaceuticals.  As we develop this list, we expect to offer detailed information on each drug to aid laypersons, health professionals, and researchers in their quest to learn what they can about the relative toxicity of these medications.

We are now in the process of developing our newest - and non-fluoride - program, the EMF Toxicity Science program, which concerns exposure to Electrical and Magnetic Fields and resulting health effects. We now have a third website-within-our-website, the EMFTS WebCenter, along with its own separate Bibliography, to provide scientific information on this controversial issue. See the Links page for a comprehensive, categorized, and annotated list of resources and links for the best organizations, services, and websites that deal with EMF health information, research, advocacy, products, and consulting.
