Best Dentist ever, Everyone in the office was very professional, friendly, and informative. My dental hygienist was very knowledgeable and helped me understand what was going on with my oral health in a way that made sense. She was friendly and it was easy to feel comfortable around her. Dr. Duncan is great, he was thorough and is genuine in his desire to help his patients understand the importance of oral hygiene and health over all. I can not say enough about how great this office is in every single way. If you have fear or anxiety about going to the dentist, Spring Smiles will eliminate all of that and become your new favorite dentist office. My wife and I will have a hard time finding a dentist office and staff to match this caliber if we ever move from NC.

I am so thankful to have a holistically minded dentist in Holly Springs! This is so important for overall health of every system in the body, not just your mouth! So many seemingly unrelated issues begin in the mouth so I am thrilled to have non toxic options so close! My experience was wonderful and every part of the team, from front desk staff, to hygienist, to the dentist was fully present with me, and all so knowledgeable! I didn’t feel like a patient filling a time slot, I felt like the priority. They explained everything so well in a way that made sense to a non dentist! I’m super thankful to have found Spring Smiles!

I love everything about Spring Smiles. They are really thorough at answering all my questions and informing me of the best options. I love the nontraditional practice that helps us integrate more natural approaches into our daily oral routine.

Spring Smiles is by far my new favorite dental team! My experience was wonderful. Their space is clean and well kept. During my cleaning, Courtney was kind, gentle, and willing to answer questions. One notable difference was their approach to patient care. All of the team takes time to get to know you — they make you feel very comfortable. The team isn’t rushing through things to get to the next patient. I cannot recommend them enough!

Dr. Duncan is extremely kind and knowledgeable and I was very impressed with him during both a telephone conversation as well as a consultation. He understood some very detailed points regarding subtle details of holistic health and the relationship of dental health to the health of the entire body. I would definitely recommend him.

Brought the kids in for cleanings and was amazed at how well they did. The hygienist was very patient and cautious; she also educated throughout the visit. It didn’t feel rushed at all, that was nice. The kids felt better here than our previous office. No unnecessary work needed at this time. We all felt very relaxed from the beginning all the way through to the end of our visit.

What a beautiful office! So glad that these folks came to Holly Springs, and easy to reach cause they’re right downtown. The thing that sets them apart from being just another dental office is their focus on holistic dentistry. If you are someone who, like me, takes their health and living a natural lifestyle very seriously, then this is the place for you. They employ modern tools and techniques, but time-tested, all-natural solutions. Power combo! Now I don’t have to pull out the periodic table of elements to figure out what they’re using on me next time I’m at the dentist office. 😃

We had the BEST experience at Spring Smiles!! Dr. Duncan and his staff are so kind, compassionate, patient, and knowledgeable! My two toddlers and I all had very positive experiences! Dr. Duncan explained everything that he was doing beforehand and in words my children could understand. He spoke TO my kids, not just over them. Which we loved! We left the office with both of them exclaiming how much they loved the dentist! (Which never happened at our previous dentist office.) They walked into Spring Smiles with a little bit of anxiety about dentists and left with no fear whatsoever! Which makes this mamas heart so happy! They even asked when they get to go back!! That alone is enough for our family to be permanent patients of Spring Smiles, but I also had a great check up! It is refreshing to find a dentist that is so well informed about dentistry and health as a whole, as it it all interlinked. We highly recommend Spring Smiles!!
