A board-certified general dentist and dental surgeon, Dr. Gangwisch has practiced in Lilburn since 1979, and has relationships with local patients that stretch back more than 30 years. Together with his colleague Dr. John Hulsey, he has cultivated a practice that specializes in taking the fear out of a trip to the dental chair. To ease the discomfort and nervousness sometimes associated with dental work, Dr. Gangwisch regularly administers a variety of anesthetics that render patients blissfully numb to a wisdom tooth's extraction and subsequent embittered insults. In addition, his staff often allays anxieties by outfitting patients with headphones tuned to pleasant music. Likewise, reclining patients can distract themselves from the dental proceedings by watching the flat-screen television mounted into the exam-room ceiling.
