With a gentle hand and an eye for perfection, Dr. Wingfield specializes in general, cosmetic, and implant dentistry in Buckhead/Midtown, Atlanta. Committed to creating the perfect smile for everyone who walks through the door, he has celebrated an illustrious dental career that has transcended country borders. He specializes in evidence-based dentistry with a focus on helping patients achieve balanced oral and systemic health and is committed to establishing a stable foundation of health through dentistry and boosting self-confidence through a gorgeous smile.

Inspired to pursue a career in dentistry by his family dentist in his hometown of Bowling Green, Kentucky, Dr. Wingfield attended Western Kentucky University where he graduated cum laude. He continued his educational endeavors at the University of Louisville and graduated with the title of the Academy of Operative Dentistry’s Student of the Year along with his dental degree. Soon after, he launched his career with the United States Navy Dental Corps and graduated with top honors from their Advanced Education in General Dentistry residency program. During his four years of service, he had the unique opportunity to serve on the forward-deployed Bravo Surgical Company in Operation Iraqi Freedom. It was there that Dr. Wingfield was able to fine-tune his craft under the most extreme situations and had his skills tested when he encountered a young Iraqi boy who had suffered severe facial injuries during a raid on his neighborhood. Dr. Wingfield expertly cared for and treated the boy, and in that defining moment, he knew that he had the opportunity to truly and positively impact the quality of life for his patients. He has received numerous awards, including a Navy Commendation Medal and two Navy Achievement Medals.

Just as passionate about education as he is about dentistry, Dr. Wingfield has logged over 1,400 hours of dental continuing education and served as Director of Education for Nanston Dental Group. His dedication to his craft has contributed to the Consumers’ Research Council of America naming him “One of America’s Top Dentists” from 2005-2010. He is a consultant for the 3M™ ESPE™ Council for Innovative Dentistry, which manufactures and markets more than 2,000 products and services designed to help dental professionals improve their patients’ oral health care, and lectures extensively on the topic of periodontal disease for Zila Pharmaceuticals. He serves on the Board of Directors for the Georgia Academy of General Dentistry and is a member of the Hinman Dental Society, Fellow with the Academy of General Dentistry, and active member of North Georgia Dental Society, Georgia Dental Association, American Dental Association, and the American Academy of Cosmetic Dentistry.
