Message From the Author
The first question people ask me is why?
Why write this book?
Why re-expose yourself to the attacks that are sure to follow?

When the NYS dental board came after me in 2005, it was by far the worst experience of my life. Up until that time I believed in our country’s system of justice. I believed in the guarantee of freedom of speech.

Furthermore, I believed my colleagues would embrace the opportunity to constantly further the science of our profession. Not so much anymore.

I expect that this book will again bring forth the personal attacks and attempts to discredit me. I have come to realize that is just the way things work. Discredit the messenger and suddenly the message is discredited too. I get it now.

In spite of all the published research to the contrary, the ADA still insists that root canal-treated teeth are safe and cannot leak bacteria or toxins to the rest of the body. It was time for a new book. The Toxic Tooth is not for people who prefer never to question established practices and the status quo, or who allow themselves to be distracted by the self-serving and blind attacks that this information is sure to provoke.

This book is for open-minded individuals who are interested in hearing an objective evaluation of the data and choose to make up their own minds.

The Toxic Tooth Summary

Over 100 years ago, Weston Price, DDS, began to demonstrate the correlation between infected teeth and systemic disease. In his meticulous research he showed that most, if not all, root canal-treated teeth were infected, highly toxic, and linked to heart disease, cancer rheumatoid arthritis, neurological disorders, and many other chronic degenerative diseases. Since that time the dental industry has tried to discredit Price’s work in an effort to “prove” the safety and efficacy of the root canal procedure.

In 2002, authors Kulacz and Levy dared to echo and turn up the volume on the warnings of Price and others about the risks of this dental therapy. Because Robert Kulacz, DDS, was so vocal about the health risks of root canal-treated teeth, he was targeted by the New York State Dental Board who attempted to revoke his dental license.

Now Kulacz and Levy double down on the powerful indictments brought in The Roots of Disease with an exposé that leaves no wiggle room for the root canal procedure or the dental/endodontics industry. They masterfully show the impossibility of sterilizing and/or sealing a root canal-treated tooth. They also document the massive failure rate of the procedure with research from the industry’s own journals. In addition, nearly 100 citations from the most current medical and dental literature solidly establish the links between root canal-treated teeth and the same systemic diseases that Weston Price reported a century earlier.
Although written for the layman, there’s more than enough science in The Toxic Tooth to counter any protest from the dental community. If you or a loved one has undergone or is considering root canal treatment, this book is a must-read. It leaves no reasonable doubt that root canal treatment can negatively impact your health. Perhaps most importantly, The Toxic Tooth will show you how to “save your smile” without endangering your long-term health.

The Roots of Disease Summary
The Roots of Disease: Connecting Dentistry and Medicine represents the collaborative efforts of a dental surgeon, Dr. Robert Kulacz, and a cardiologist, Dr. Thomas Levy. For almost a decade now, these two health care professionals have had the opportunity to directly observe the enormous negative impact that infective dental toxicity has had on the health of many patients. Drs. Kulacz and Levy have also found that the removal of, and complete healing of, sites of infective dental toxicity can often result in seemingly near-miraculous improvement in many of the patients so treated. At the very least, substantial improvements in the clinical conditions and abnormal laboratory profiles of many patients have been observed very frequently by the authors.
Hopefully, this book will both educate and enrage its readers. The appendices in this book further attempt to demonstrate to the reader that a very large amount of hard scientific data already exists to support all of the assertions made. Dentistry and medicine must always be practiced in conjunction with each other, although presently such collaboration is rarely found. Dentists and physicians need to become working colleagues on a regular basis.
