Compare
Every sub-score, printed as is
The ranking is the plain sum of the numbers in this table — you can check it without a calculator. Specialists and cone-beam CT units follow HIRA registration; visitor review counts come from Naver Place.
Google ratings are collected from Google Maps and shown for reference only — they never enter the score. Clinics with no rating collected are left blank.
Insight
What stands out in Gangseo-gu, Seoul
Diagnostic equipment
10 of the 10 clinics listed have a cone-beam CT registered, 12 units in total. 더와이즈치과병원 has the most at 2. Unit counts follow HIRA registration.

Years in operation
The longest-running is 강서예치과의원, opened in 2005; the newest is 365서울원탑치과의원, opened in 2018. That is a 13-year spread, which is worth reading alongside review counts — an older clinic has simply had more time to collect them.

FAQ
Frequently asked
How was this ranking of orthodontic clinics in Gangseo-gu, Seoul decided?＋
We add up published facts on a 20-point scale: years open, how many visitor reviews have accumulated on Naver and online information on the clinic's website for every treatment, plus treatment-specific HIRA records such as registered specialists and cone-beam CT units. Every sub-score is printed in the comparison table so anyone can recalculate it, and no clinic can pay to move up.
Does this ranking measure clinical skill?＋
No. It ranks how much public evidence can be verified, not treatment outcomes. The right clinic depends on your own condition, so confirm the details in person at a consultation.
Which clinic in Gangseo-gu, Seoul has registered the most cone-beam CT units?＋
더와이즈치과병원 has 2, the most among the 10 clinics listed. A cone-beam CT scans bone thickness and nerve canal position in three dimensions; unit counts are as registered with HIRA.
Which clinic has the most registered specialists by field?＋
더와이즈치과병원, with 9 in total. The breakdown is Oral & Maxillofacial Surgery (1), Prosthodontics (4), Orthodontics (1), Periodontics (2), Advanced General Dentistry (1).
Which clinic has the most Naver visitor reviews?＋
이편한세상치과의원(화곡점), with 5,551. These are reviews left by people whose visit was recorded. The count reflects how much visit experience has accumulated, not how good the treatment is.
Which clinics have more than 1,000 visitor reviews?＋
8 of the clinics listed here — 더와이즈치과병원 (2,810), 365서울원탑치과의원 (2,381), 아이디마곡치과교정과치과의원 (2,136), 타임치과교정과치과의원 (1,073), 강서예치과의원 (3,043), 서울리더스치과의원 (1,004), 다온미소치과의원 (1,085), 이편한세상치과의원(화곡점) (5,551).
Are any of these 10 clinics a dental hospital rather than a clinic?＋
더와이즈치과병원 is registered as a dental hospital. The rest are dental clinics. The category follows HIRA registration.
Which clinic in Gangseo-gu, Seoul has been open the longest?＋
강서예치과의원, established in 2005. Opening dates follow HIRA registration.
Which clinics have a registered orthodontist?＋
7 of them — 더와이즈치과병원 (1), 365서울원탑치과의원 (1), 아이디마곡치과교정과치과의원 (1), 타임치과교정과치과의원 (1), 아너스치과교정과치과의원 (1), 서울리더스치과의원 (1), 주치과교정과치과의원 (1). For orthodontics, whether an orthodontic specialist is registered is the key published signal: each one scores 2 points, up to 4.
What should I ask at an orthodontic consultation?＋
Ask for the expected duration and cost per appliance type, whether monthly adjustment fees are included, the price of retainers, and the refund rule if you transfer mid-treatment — in writing. Also see whether the plan is explained from diagnostic records such as a cone-beam CT and a lateral cephalometric X-ray.
Why is 더와이즈치과병원 listed first?＋
It scores 16 points, the highest here. That comes from 9 registered specialists, 2 cone-beam CT units and 2,810 Naver visitor reviews. The sub-scores are shown in the comparison table.
Where does the information on this page come from?＋
Specialists, cone-beam CT units, opening dates and facility category come from Health Insurance Review and Assessment Service (HIRA) open data; visitor and blog review counts come from Naver Place. We have no partnership with any clinic, and the collection period is printed at the bottom of the page.
How this page was built, and what it cannot tell you
Specialist mix, cone-beam CT units, opening dates and facility category come from Health Insurance Review and Assessment Service (HIRA) open data; visitor and blog review counts come from Naver Place. Data was collected between 2026-09-21 and 2026-09-26, and a clinic that changes its filing can differ from what is shown here.
Implant brands, the extra cost of a bone graft, which dentist actually performs the surgery, and warranty terms are not in any public record. Those belong in a consultation, in writing. This ranking orders how much published evidence can be verified — not how good the treatment is.
