John S. Echternach, DDS

John S. Echternach, D.D.S., is a retired general dentist who maintained a private practice in Henniker, NH, for 40 years.  He has been an active member of the American Dental Association, the New Hampshire Dental Society (NHDS) and Concord Dental Society (CDS). His role in organized dentistry includes more than 16 years in a leadership capacity in both the NHDS and the CDS.

In his retirement, John has assumed the role as a teacher of healthcare professionals with his focus on a specific treatment: the science and clinical applications of silver diamine fluoride (SDF).  After learning about the uses of SDF toward the end of his career, he successfully used this method on both children and adults for the last three years in his Henniker practice.

In his spare time, Dr. Echternach enjoys bike riding and power walking with his wife, Judie.  He also practices tai chi and tinkers with old clocks in his cozy clock shop.
