Dr. Sandra Lee Armstrong

Pediatric Dentistry General Dentistry


Sandra Lee Armstrong, DDS Dr. Sandra Lee Armstrong is a 1988 graduate of the University of Texas Health Science Center Dental Branch in Houston, Texas. After graduating from dental school, Dr. Armstrong attended a pediatric dental residency program at the University of Texas Health Center at Houston. She received intensive oncology training at MD Anderson Hospital, special patient training at Richmond State School, hematology and AIDS management at Gulf States Hematology Clinic and pediatric medicine and anesthesiology at Hermann Hospital. Dr. Armstrong decided to become a pediatric dentist at the age of 15. She began working for a pediatric dentist in Odessa, Texas as summer employment during junior high and high school. Through those years, she not only obtained a rich experience and education providing for children, but she also developed a love and admiration for that population. Sharing with children and helping them overcome their fear as it relates to dentistry is one of her many talents. Dr. Armstrong has been in private practice since 1988 and has served the Grapevine/Southlake area since 1991. Trained in the full spectrum of pediatric and adolescent dentistry, Dr. Armstrong is also an active member of the American Academy of Pediatric Dentistry, the Southwestern Society of Pediatric Dentistry and the American Dental Association. Dr. Armstrong is the genuine West Texas cowgirl turned pediatric dentist. With her blend of spirit and an extensive professional education, she excels in the profession of children’s dentistry. Being from the Lone Star State, she’s a natural at hospitality, valuing most the gift of relationship, which makes her a perfect choice for the young and/or anxious dental patient. This practice of pediatric dentistry, like no other, rests in the proud city of Southlake, Texas. Dr. Armstrong hung her shingle in the Metroplex in 1991. She developed a “sports” centered practice, which couldn’t be more suiting for the child athletes and participants who homestead in Southlake. Her attention to detail is fascinating and can be witnessed by her office environment created for her by Thiel and Thiel, a local architecture/decorating firm. Being the proud Texan she is, she boasts state-of-the-art furnishings and personal acknowledgements from our own Lance Armstrong, Nolan Ryan and Roger Staubach. It’s not, however, her office that makes Dr. Armstrong the choice of her peers as an outstanding doctor. Dr. Armstrong is consistently on the road pioneering a new and better way to provide preventive dentistry. She is tireless in acquiring the latest in dental technology to better the overall health of those for whom she cares. Board Certified in the specialty of pediatric dentistry, Dr. Armstrong is outstanding in her field. Please take the time to stop by this joy filled office for a genuine Texas welcome! Dr. Armstrong and her staff will be delighted to show you the duds and offer education or advice regarding pediatric oral health. In case you’re looking for Dr. A, she’s the one with the spurs.

"I would definitely give this practice a 5-star rating! After a negative experience at another dentistry, I was hesitant to take my son for his first visit. But I was pleasantly surprised by the wonderful experience we had at this child-friendly dentistry. The staff were incredibly welcoming and kind, and they made sure my son felt comfortable throughout the appointment. I couldn't have asked for a better visit, and I'm grateful to have found such a fantastic dental practice!"
