Your Holly Springs Dentist

Get to Know Dr. Duncan

Dr. Gabriel Duncan earned his Doctor of Dental Surgery at UNC Chapel Hill School of Dentistry in 2012. While there he was honored to travel to Eastern Europe as a student-dentist as well as volunteer at the local SHAC clinic and the North Carolina Missions of Mercy Dental clinic. He was also a member of Delta Sigma Delta honor society. While serving in the orphanages of Moldova he had the privilege to provide dental treatment to the children with no access to dental care. He counts this as one of the most rewarding and life-changing experiences he’s ever had.

As a child Dr. Duncan was terrified of the dentist. It wasn’t until the age of 13 when an accident with a hammer prompted the need for an emergency dental visit. The care and skill his dentist displayed that day slowly began to change Dr. Duncan’s perception of dentistry. Many years later when he was considering dental school, he went back and shadowed the very dentist who had helped him, and it was at that visit It was then that he decided this was his life’s work. Dr. Duncan cares about his patients and applies the same level of care to them as his dentist did for him years ago. His goal is to build relationships, relieve discomfort and prevent large dental problems by fixing them while they are still small.

A self-described “education junkie”, Dr. Duncan is constantly learning and improving ways to provide the most advanced and quality dentistry to his patients in the most gentle and conservative way. Dr. Duncan is always adding to his dental knowledge so that he can provide the best care possible. He believes in in utilizing the latest advancements in education and technology, such as low-radiation Cone Beam 3D technology to bring the best in prevention and treatment to his patients.

Dr. Duncan is an active member of the Academy of General Dentistry, having successfully completed the Fellowship Exam in 2018. He is also an active member of Spear Education, IAOMT, CEREC doctors, and the ICOI (International Congress of Oral Implantologists). Dr. Duncan is grateful to be able to provide a full range of services, including Invisalign, Myo Munchee and Myobrace to patients of all ages.

Outside of the office Dr. Duncan enjoys traveling, volunteering, working out and spending time with his family.

Air Filtration System

We have a Airdec Filtration system that not only removes mercury particles from the air during our S.M.A.R.T. procedures but also other bacteria in the air such as covid and mold spores.  We also have 2 Medify Air filtration systems that run all the times to constantly purify our air in the office.  We have one in the back of the house and in the reception area. Spring Smiles also work with Medlin Davis cleaners to have all our scrub jackets, and lab jackets professionally cleaned after every shift.

Intertek tested Medify’s MA-40 and MA-50 air purifiers against COVID-19 and SARS-Cov-2 and the results are in - we successfully removed 99.9% of harmful particles from the air.
