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

Dr. Preetha Thomas'office is mercury-free (amalgam/silver filling-free) and mercury-safe and she is dedicated to practicing safe and healthy dentistry.  Her mission is to share information about all aspects of dental wellness with her patients so that they can make educated decisions about their oral health.  She fully understands the important relationship of oral to overall health and realizes that; "You cannot be truly healthy without good oral health!"

Holistic Dentistry
Holistic 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 healthy treatment options. Given her advanced training and emphasis on total health, Dr. Thomas 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 her patients' physical and emotional well-being and comfort.

Safe Amalgam/Silver Filling Removal Protocols
As your Oral Health Doctor, Dr. Thomas is aware that mercury vapor, dental infections, and TMJ (bite) problems can have a negative impact on oral and overall health. Because of this concern, we focus on patient education and strive to remove mercury amalgam (silver) fillings in a safe way.

We believe it is important to protect the patient, the environment, and our staff from exposure to excessive and unnecessary occupational exposure to mercury during the amalgam removal process. Doing so is supported by the ADA and other dental organizations. For information about why it's important to use a mercury safe dentist, Click Here.

To accomplish this, we utilize safe amalgam 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 removal protocols and an explanation of what they are, Click Here.

Whole Body Dental Philosophy
Dr. Thomas ' Whole Body philosophy also stresses the use of biocompatible dental materials whenever possible. She also works closely with highly qualified health professionals to assist her in her efforts to return the patient to optimal oral and overall health. Her Holistic - Patient First - approach to dentistry means that she treats the teeth, jaw, and related oral structures, with specific regard to how that treatment will affect the entire body.

Continuing Education
Dr. Thomas is a strong advocate of continuing education because it allows her to give you and your family the best, state-of-the-art dental care. Each year she takes many hours of continuing education courses in holistic and conventional dentistry in order to provide her patients with the most advanced dental care possible.

NEW! Dr. Tom McGuire's new Video, Mercury: The Poison in Your Teeth conclusively proves that amalgam/silver fillings not only release toxic mercury vapor - but that the common act of brushing just one amalgam filling - will release more mercury than allowed by governmental regulatory agencies at the workplace! It also tells you what you can do about it. Click Here to watch this amazing video demonstration - and don’t forget to tell your friends and family!
