What is Gangnam One Day Dental Clinic?
Gangnam One Day Dental Clinic (원데이치과의원, Oneday Dental) is a dental clinic in Yeoksam-dong, Gangnam, Seoul, founded in May 2002. It has 13 dentists in five departments, three buildings totalling about 1,570 m², and an in-house lab, Oneday Lab. Its philosophy is treatment completed in fewer visits, supported by 3D CT, digital scanning and T-Scan bite analysis.

Our philosophy: treatment completed in fewer visits
Every extra appointment costs patients time off work, travel and, for many, anxiety. Since 2002 the clinic has organised its people, equipment and lab so that treatment can be completed in fewer visits without skipping steps. Accurate diagnosis comes first; speed is only offered when the case allows it.
That is why the clinic invests in 3D CT, intraoral scanning, CAD/CAM milling and its own lab. About 60% of implant patients travel from outside Seoul, and many international patients plan around fixed dates, so fewer visits makes a real difference. See our international patients guide.
The team
Chief Director Dr. Kim Jin-hwan focuses on implant surgery, T-Scan occlusion therapy and TMJ. He is Vice President of the Korean Academy of Stomatognathic Function and Occlusion (2026-2027; academy established 1980) and wrote the chapter "Controlling the Occlusion of Implant-Supported Restorations" in the IGI Global Handbook of Research on T-Scan Technology Applications in Dental Medicine, edited by Robert B. Kerstein.
Dr. Kim Do-hoon, Chief Director of Orthodontics, leads general, lingual, clear/Invisalign, protrusion and surgical orthodontics. They work with 11 colleagues across five departments.

Korean audioThings to know before you decide
- Fewer visits is a goal, not a promise: bone grafts, conventional implants and orthodontics still need healing or adjustment time.
- One-day prosthetics depend on the case; the dentist confirms after examination.
- Estimates given on WhatsApp are provisional until an in-person exam and 3D CT.
- The clinic handles all inquiries on WhatsApp only; there is no phone line or contact form.
