Where can I get orthodontic treatment in Seoul?

Options include metal braces, self-ligating Clippy-C braces, lingual braces, Invisalign and other clear aligners, and protrusion and surgical orthodontics.

One orthodontic department, every main appliance type
Orthodontics at Gangnam One Day Dental Clinic is a separate department, not a side service. It sits in our third building, the Heungkuk Fire Insurance Building 8F at 442 Gangnam-daero, Yeoksam-dong. Dr. Kim Do-hoon, Chief Director of Orthodontics, leads general, lingual, clear aligner and Invisalign treatment, protrusion correction and surgical orthodontics.
Because one team offers fixed braces and aligners, the appliance is chosen for your bite, not the other way round. How teeth move and how each appliance type compares are explained below.
- Fixed braces: metal braces and self-ligating Clippy-C braces
- Hidden or removable: lingual braces, Invisalign and other clear aligners
- Bite and profile: overbite, buck teeth, protrusion and surgical orthodontics
- Children: children's orthodontics within our family dentistry
How teeth actually move
Each tooth sits in bone, held by a thin ligament. When a brace or aligner presses gently on a tooth, bone on the pressure side is resorbed and new bone forms on the other side. The tooth travels with it, usually at around 1 mm per month.
This is why orthodontics cannot be rushed. Heavy force does not speed it up; it raises the risk of root shortening and gum problems. Planned, light force is safer and more predictable.

All appliances use the same biology. They differ in visibility, control, comfort and how much the patient has to do.
- Metal braces: brackets and wires; the widest control for complex movement. See metal braces.
- Self-ligating braces: brackets with a built-in clip instead of elastic ties, such as Clippy-C braces.
- Lingual braces: brackets bonded behind the teeth, hidden from view.
- Clear aligners: a series of removable trays worn 20–22 hours a day, such as Invisalign.
- Retainers: fixed wires or removable trays that hold results after treatment.
Which problems orthodontics can correct
Orthodontics moves teeth slowly through the bone with light, steady force. It treats crowding, gaps, rotated teeth, deep bites, open bites, crossbites and forward-flared front teeth. Where the jaw itself is the cause, orthodontics may be combined with jaw surgery, which Dr. Kim Do-hoon plans as surgical orthodontics.
Many adults come to us for protruding front teeth. Our page on protruding front teeth explains when extraction space is needed and when it is not.
Planning starts with records, not a sales quote
A plan needs X-rays, photos and an intraoral scan or impressions. From these the orthodontist measures tooth position, jaw relationship and available space before suggesting an appliance and a time frame.
You can start on WhatsApp by sending clear smile photos and any recent X-rays. The team replies in English, Chinese, Japanese or Korean with which options look realistic and what the in-person examination will confirm.
Signs you may benefit from orthodontics
Orthodontics is not only cosmetic. Crowded teeth are harder to clean, and a poor bite can wear teeth unevenly or overload certain teeth. Common reasons people seek treatment include crowding, gaps, a deep bite, buck teeth, crossbite and front teeth that flare forward.
Not every concern needs braces. Small chips or shape issues may be better solved with bonding or veneers, and the orthodontist will tell you when tooth movement is not the right tool.

Things to know before you decide
- Orthodontics takes months to years; short trips to Seoul are rarely enough to complete treatment.
- Poor brushing around braces can cause white spots, decay or gum inflammation.
- Some root shortening and mild soreness after adjustments are known effects of tooth movement.
- Teeth relapse without retainers; long-term retainer wear is usually needed.
- Active gum disease must be controlled before orthodontic treatment starts.
