in Songdo, Incheon
Real cases, real results. See the complete journey of Class III malocclusion (주걱턱) correction — from active treatment to final bite. Serving Songdo's expat community.
What Is an Underbite (주걱턱)?
An underbite — clinically classified as a Class III malocclusion — occurs when the lower jaw protrudes further forward than the upper jaw, causing the lower front teeth to sit in front of the upper teeth when biting down. It's one of the most common orthodontic concerns among the international community in Songdo, Incheon.
Beyond aesthetics, an untreated underbite can affect how you chew, speak, and feel day to day. The good news: modern orthodontic treatment offers effective correction for most cases — including Invisalign clear aligners, traditional braces, or a combination approach.

Prefer a More Discreet Option? Invisalign Works Too.
While braces are often the most effective tool for significant underbite correction, Invisalign clear aligners are an excellent option for mild to moderate Class III cases — and many of our Songdo expat patients prefer the invisible, removable approach.
With the addition of Class III elastics, Invisalign can address both the dental and mild jaw components of an underbite — all without metal brackets showing in your smile.
- Nearly invisible during wear
- Removable for eating, brushing, and social occasions
- 3D simulation shows results before you start
- Class III elastic compatible hooks available
- Comparable treatment time to braces in suitable cases

What Our Expat Patients Say
Experiences from international residents treated at our Songdo clinic.
"I had a moderate underbite and was worried about finding quality orthodontic care in English. The team at Songdo Dental walked me through everything clearly — treatment plan, elastic usage, progress checks — all in English. Remarkable results."
"My son had a Class III bite and we were nervous about navigating dental treatment in Korea. The staff made it so comfortable — and the before/after difference is genuinely life-changing. We're so grateful we found this clinic."
"I chose Invisalign for my mild underbite because I didn't want obvious brackets at work. The 3D simulation was impressive — I could see exactly what my final bite would look like. 15 months later, exactly as promised."
