“I haven't been to the dentist in a LONG time, so I was nervous about going. When doing in-take forms, there were questions about how long ago my last visit was, if I was nervous about going, and about my teeth sensitivity. Dr. Keynton and her staff was amazing! She walked me through the whole appointment from start to finish, described everything she was seeing and doing, and gave me good recommendations. Some of my teeth were very sensitive, and she and her assistant were very calming, allowed for me to take breaks, and were very comforting. I usually don't write reviews for anything, but really felt compelled to write this one!”

“Found this practice on Zocdoc since I'm new to the area and needed a good dentist. My first appointment was easily booked, they saw me right away (which was earlier than the booked time), and were very accommodating with my needs. ”

About Dr. Megan A. Keynton Sill
You can call me Dr. K! I was lucky enough to find my passion for serving others at the age of eight when I participated in my first school community service project working with homeless families. As I got older, I realized that my passions for serving others, art and science could all be embodied in Dentistry. I returned to where I grew up to attend the University of Louisville to earn my Doctorate of Medicine in Dentistry. Following graduation, I went on to participate in an Advanced Education in General Dentistry residency with East Carolina University where I gained extensive training in cosmetic and esthetic dentistry, prosthodontics, oral surgery and implant dentistry.
The opportunity arose to be closer to family in the Northern Virginia area so I made the move and I have loved it ever since! I met Dr. Hubbard and we became instant friends. The decision to become a part of the awesome team at Sterling Virginia Smiles was an easy one. I’m thrilled to have a team that shares my dedication to patient-centered care and providing the best experience possible for all our patients. I consider my patients like family and I love helping them achieve their ideal smile and getting back to optimum oral health.
In a world of ever-changing technology, I strive to stay up-to-date on the most current dental methods and techniques in order to provide the highest quality care to my patients with all of their dental needs by attending continuing education seminars.
When I’m not at the office, you can find me spending time with family and friends. My husband and I love to travel around the country and world to explore new cultures and experiences. One of my favorite experiences while traveling has been taking a cooking class in Italy learning to make homemade gnocchi.
