Seoul Gangnam

Yonsei First Oral Medicine Dental Clinic (co-directors Dr. Lee Jeong-eun and Dr. Woo Geon-cheol) is an oral medicine dental clinic on the 7th floor of the Hyecheon Building at 354 Gangnam-daero, Gangnam-gu, Seoul. Oral medicine deals with pain and function of the jaw and mouth rather than the teeth themselves, including TMJ disorders, grinding and clenching, snoring and sleep apnea, and persistent mouth ulcers and dry mouth, and specialists in this field are rare. Both co-directors hold doctorates from Yonsei University College of Dentistry and teach there as adjunct professors; they image both jaw joints at once with a low-dose cone-beam CT and link quickly to MRI at a partner hospital when needed. Treatment combines custom splints, in-house snoring devices, the clinic’s T-tox method pairing trigger-point injections with Botox, and physical therapy. With evening hours until 9 pm on Tuesdays and Thursdays it is easy to fit into a trip, and if you send your symptoms and schedule through MediQueen we will help with consultation, interpretation and booking.

Oneday Dental (Chief Director Dr. Kim Jin-hwan) runs Clinics 1 and 2 (implants) and Clinic 3 (orthodontics) in Yeoksam-dong, Gangnam, with the in-house OneLab on the 14th floor and a surgery lounge on the 15th. Its one-day implant pathway goes from diagnosis (3D CT and intraoral scan) to immediate placement, same-day prosthetics at OneLab and a T-Scan bite check, with PlasmaONE supporting early bone integration. On 4 October 2026 MediQueen refreshed the clinic page from materials provided by the clinic and named Oneday Dental its No.1 flagship clinic. International patients can be assisted in English, Chinese and Japanese, and MediQueen coordinators arrange consultation, booking and interpreting.
