Meet the Doctors


Dr. Carla J. Spann, D.D.S.

Doctorate of Dental Surgery, Texas A&M University Baylor College of Dentistry - Dallas, TX.
Bachelor of Science in Electrical Engineering, Duke University School of Engineering – North Carolina

Dr. Carla J. Spann, D.D.S. has great memories of growing up in a small town in New Jersey. She loves that even as Allen has grown, it’s still retained that same ‘small town’ feel.

“As a kid, my dentist lived a few houses down from me,” Dr. Spann recalls. “I went to the same high school that my parents went to. It was nice because everyone knew everyone else. That’s part of why I love Allen. I live here; I work here; my kids play soccer here. There’s a great sense of community.”

Conservative approach 

Dr. Spann offers a compassionate and conservative approach to dentistry. She believes that patient education is paramount to success in both resolving and preventing oral health issues. She also practices a team approach to general dentistry, coordinating the execution of complex dental treatment plans in close communication with dental specialists and her patient's medical physicians as needed. She is particularly skilled in helping fearful patients relax during their dental care and is certified to provide sedation for these patients when necessary, as well.

“My definition of conservative goes beyond not over-treating patients, but preserving tooth structure, taking preventive measures to reduce tooth decay and providing all options to patients,” she explains. “I encourage them to restore their teeth rather than extract them, whenever possible.”

Dr. Spann is a devoted mom of two boys, Carson and Cameron, who attend Lucas Christian Academy. Dr. Spann is also the proud daughter of the late Calvin J. Spann, who is an original Tuskegee Airman Pilot.

In her free time, Dr. Spann enjoys reading, movies, playing golf, cooking, and spending time outdoors.

Education and memberships 

A strong believer in keeping her knowledge and skills current, Dr. Spann has completed numerous continuing education courses and is an alumnae of the prestigious Pankey Institute in Key Biscayne, Florida where she has expanded her knowledge of principles of general dentistry to incorporate all aspects of patients’ oral health, nutrition and medical systemic conditions in her practice philosophy.

Dr. Spann, D.D.S. previously served as a part-time faculty member at the Texas A&M Baylor College of Dentistry and is an active member of:

  • The American Dental Association
  • The Texas Dental Association
  • The Dallas County Dental Society,
  • The Dallas Academy of General Dentistry
  • Christian Medical and Dental Associations
  • The Allen-Fairview Chamber of Commerce
