Director Heewon Seo's story

A pediatric dentist who never loses sincerity

Why I became a dentist

For me, whether in clinical care or in meeting people, the most important value is sincerity.

There wasn’t a particular incident that made me become a dentist, but approaching people with genuine sincerity has always guided my life in a positive direction. Seeing patients in pain regain comfort through treatment, and helping that change up close, gave me great fulfillment, and those experiences naturally gave me the conviction to choose the path of dentistry.

Clinical expertise

As a board-certified pediatric dentist, I understand children's developmental stages and provide treatment and behavior management tailored to their pace of development, and I'm confident in this approach.

"Children are not small adults"
Children need an entirely different approach.

Even with the same symptoms, treatment varies by age, stage of development, and level of cooperation, and during care we also need to address emotions such as fear, anxiety, and curiosity. I consider it a strength to understand these complex factors in depth and tailor my approach to each child.

Treatment Style

If I were to express my treatment style in one sentence,

"Carefully meeting a child at their level and providing safe, precise care in a short, efficient visit."

A dental office can feel unfamiliar and stressful for a child. So from the first explanation through the procedure, I present everything in ways a child can understand, and I aim to deliver precise care in the shortest reasonable time to reduce their burden and fatigue.

Care Philosophy

The principle I value most is

"Care that understands development; treatment that considers emotions."

Pediatric care is not just about fixing cavities; it must consider the child's overall growth. Even with the same condition, diagnosis and treatment differ by developmental stage, and the way we approach care also changes.

Because fear and anxiety affect not only a child's cooperation but also their future dental experiences, I always work to ensure the child experiences trust, not trauma, through the treatment process and design their care accordingly.

Advice for Parents

I always emphasize to parents keeping regular brushing times and using dental floss daily as essential.

Regular fluoride applications are helpful, but ultimately the key to oral health lies in habits and daily home care. Because prevention is more powerful than treatment, I believe daily care is the foundation of all treatment.

Most Memorable Case

The most memorable case was the first I handled during my residency: a 3-year-old patient.

The child presented with a suspected periodontal abscess, but the radiograph suggested a possible malignancy, so a precise differential diagnosis was needed. It could easily have led to inappropriate treatment in another department, but with the right diagnosis and referral, the child was ultimately diagnosed early with leukemia.

It made me realize that an initial pediatric dental visit can go beyond a simple tooth problem and serve as an important gateway to protecting a child's overall health.

Current Interests

Lately, I have been studying clear aligner orthodontics, including Invisalign more systematically.

Because changes in the dentition during growth are intricately interrelated, I focus not merely on placing appliances, but on deepening my understanding of which treatments are most appropriate at each developmental stage. Orthodontic care during growth is a pivotal period that shapes a child's future oral health, so it requires an even more careful and systematic approach.

A Personal Note

My colleagues describe me as "a people person who naturally brightens the mood"they say. I enjoy meeting new people, and I also like organizing small get-togethers where those around me can connect.

This trait naturally shows in the treatment room as well, helping children feel at ease and giving parents a sense of trust.

Currently a parent of two children, I stay deeply engaged with children’s development, education, and emotional changes even outside the clinic. I find joy in everyday moments with my children, and these experiences add meaningful depth to my perspective and approach as a pediatric dentist.

At Seoul BD Dental, there’s just one experience I want children and their parents to have.

"This isn’t a scary dental office; it’s a comfortable place we can trust."

To help turn a dental visit—which can feel unfamiliar and scary—into a positive memory,
I will do my very best to provide care that never loses sincerity.

Interview with the Director

Dr. Heewon Seo shares her story

As a pediatric dentist, what matters most to you?

Children are not small adults. Even with the same symptoms, treatment methods differ depending on age, development, and level of cooperation, and we must address emotions like fear and tension as well. Care that understands development and considers emotions is the core of my practice.

What do you do when a child is afraid of the dentist?

For a child, the dental office can feel unfamiliar and stressful. From explanations to each step of treatment, I tailor everything in ways the child can understand, and I aim to deliver accurate care in the shortest reasonable time to reduce burden and fatigue. I design visits so children experience trust, not trauma.

Any message for parents?

Please keep regular brushing times and use floss daily. The key to oral health is habit and everyday care. Prevention is more powerful than treatment, so daily home care is the starting point for every visit.

As a mother of two, does that help with pediatric dental care?

Yes. Even outside the clinic, I pay close attention to children’s development and emotional changes. Everyday experiences with my children add meaningful depth to my perspective and approach as a pediatric dentist.

Care Philosophy

"Care that understands development, treatment that considers emotions."

Pediatric care is not just about treating cavities; it must consider the child’s 'entire growth process.' Even with the same condition, diagnosis and treatment differ by stage of development.

Fear and anxiety affect not only a child’s cooperation but also their future dental experiences. I always aim for the child to experience trust—not trauma—during treatment by how I design their care.
