What is a holistic dentist? 

Thank you Jindalee for the dentist info.Do the services covered by insurance company just like regular dentist?

This is the definition of holistic dentist (from wikipedia):

Holistic dentistry also called alternative dentistry, unconventional dentistry, biologic dentistry, or biocompatible dentistryemphasizes approaches to dental care which consider the patient's dental health in the context of their entire physical as well as emotional or spiritual health in some cases. It is part of the alternative health movement. Although the holistic dental community is diverse in its practices and approaches, common threads include strong opposition to the use of amalgam which contain mercury and other potentially toxic materials in dental fillings, nonsurgical approaches to gum disease, and the belief that root canals may endanger systemic health of the patient through the spread of trapped dental bacteria to the body. Many practices and opinions among alternative dentists are criticized by the mainstream dental community and skeptics of alternative medicine in general.

He is a qualified dentist (Doctor) so I imagine the medical insurance will reimburse if you have the covering for dental costs.

Hope that answers the question

Have you consulted Dr. Leopold Kun?  How good is he and does he have alternatives to root canals and gum disease? Thanks very much
