Mercury Free (Amalgam Free), Mercury Safe, Holistic, Cosmetic, Family and Sports Dentistry

Dr. Leonard Fazio has practiced mercury free, mercury safe, and metal free dentistry since 1993 and he is dedicated to the practice of holistic, integrated dentistry. He was trained by the renowned Hal Huggins D.D.S., and continues to expand his knowledge on all complementary therapies and protocols used to promote oral and overall health.

His goal is to treat his patients in the most healthy, caring, holistic way possible and to share information about dental wellness with his patients so that they can make educated decisions about their oral health. He fully understands the critically important relationship of oral to overall health and realizes that; "You cannot be truly healthy without good oral health!"

Safe Mercury Amalgam Filling Removal Protocols
As your Oral Health Doctor, Dr. Fazio is aware that mercury vapor, dental infections, and TMJ (bite) problems can have a negative impact on oral and overall health. Because of these concerns, we focus on patient education and strive to remove mercury amalgam (silver) fillings in a safe way. For information about why it's important to use a mercury safe dentist, Click Here.

To accomplish this, we utilize safe & proven removal protocols based on recommendations of the International Academy of Oral Medicine and Toxicology (IAOMT) and other prominent biological and holistic dental organizations. For more information about why we use safe protocols to remove amalgam fillings and an explanation of what they are, Click Here.

Dr. Fazio has taken patient protection to a new level. He created and designed a Safe Room for mercury amalgam silver filling removal. This environmentally controlled treatment room is a well-designed and beautifully appointed dental operatory, built specifically for the purpose of providing a mercury-safe haven for patients seeking replacement of mercury-amalgam/silver fillings. This “positive-pressure” dental and surgical “clean room” was constructed to insure that the ambient environment would be the safest, most comfortable space to undergo dental treatment of any kind.

Holistic Dentistry
Holistic/Biological Dentistry is a philosophy that recognizes that the teeth and associated oral structures are a part of the whole body. Because of this important relationship, we offer a wide range of treatment options. Dr. Fazio also takes a unique Whole Body approach to oral health care; combining sound dental science, modern technology, and years of experience with a deep concern for his patients' physical health and emotional well-being and comfort.

Whole Body Dental Philosophy
This Whole Body philosophy stresses the use of biocompatible dental materials whenever possible. He also works closely with highly qualified health professionals to assist him in his efforts to return the patient to optimal oral and overall health. His Health-Focused - Patient First approach to holistic dentistry means that he treats the teeth, jaw, and related oral structures, with specific regard to how that treatment will affect the entire body.

Advanced Education 
Dr. Fazio believes that continuing education is a powerful tool that allows him to give you and your family the best, state-of-the-art dental care. Each year he takes many hours of advanced continuing education courses in many areas of holistic and traditional dentistry.
