Dr. James Tong

Dr. James Tong

Board Certified Pediatric Dentist

With more than 30 years of clinical dental experience, Dr. James Tong has been practicing pediatric, orthodontic and family dentistry in Montgomery County for more than 20 years now.

Dr. Tong became interested in dentistry at an early age. His father was a chemistry professor at a medical school and his mother was a periodontist. As a boy, Dr. Tong was an outstanding student, but he developed a life-threatening heart condition that forced him to drop out of school. Nevertheless, he studied hard at home and in 1977, he was admitted to the West China University School of Medical Sciences. There, he earned a Bachelor's degree in Stomatology, and later, Master's and Doctoral degrees in Orthodontics.

After relocating to the United States in 1991, Dr. Tong earned a specialty certificate in Pediatric Dentistry from the University of Maryland Dental School. He currently serves as a clinical faculty member in the department of Orthodontics. Dr. Tong is a leader in his dental field and a respected member of his community. He is an active member of the American Academy of Pediatric Dentists, the American Association of Orthodontics, the American Society of Dentistry for Children and the Maryland Academy of Dentists.

In addition to his work and continuing education, Dr. Tong is an accomplished violinist and landscape photographer. He lives in Gaithersburg with his wife and their two children.

Our Services

Children’s Care

From infants to teens, our skilled dental team is familiar with the unique needs of every patient, no matter their age. Our goal is to help them develop great oral habits that will last them a lifetime.

Digital X-Rays

Our use of digital x-ray technology reduces radiation exposure and eliminates the use of chemicals. It’s better for your child and the environment. It's also easy to see what the doctor sees, and make informed choices about treatment.

Professional Cleanings

Professional cleanings form the foundation for preventing gum disease and tooth decay. We provide a gentle and thorough cleaning of the teeth and mouth and finish with a polish that removes stains from your child’s teeth.

Dental Fillings

The common silver filling contains mercury. Our doctor uses the highest-quality biocompatible, tooth-colored restorations to create healthy, beautiful smiles without all of the prep-work associated with traditional fillings.


Protect and keep badly decayed or fractured teeth while maintaining a beautiful smile. Made to perfectly match the shape and shade of your other teeth, they’re durable, strong, and undetectable.

Patient Comfort

Our office was designed with your child in mind. Our unique atmosphere helps children relax and enjoy their dental experience. Children deserve to experience a gentle, caring approach to dental care.
