Hello.
This is Smile D Dental Clinic.
At Smile D Dental Clinic, three specialists work together in collaboration, and over the past 18 years, we have handled more than 5,000 diverse clinical cases.
We strive to plan and provide treatment that is appropriate for each patient’s condition.

You went through orthodontic treatment with determination, but ended up with a sunken-lips look.
We have met many people who quietly feel hurt because of these symptoms after orthodontic treatment.
Today, let’s look at why this happens and how to solve this challenging problem.

Could It Be About Me? Signs of Retracted Incisors
Retracted incisors refer to upper front teeth that have moved inward.
Normally, teeth should be angled forward by about 15 degrees, but
retracted incisors are characterized by extending in the opposite direction. At this time, what you may notice includes

Aesthetic concerns
The lips curl inward, losing volume, and as the angle between the nose and upper lip (the nasolabial angle)
becomes larger than the normal range (95–105 degrees), the philtrum appears longer. This makes the midface
look longer, creating the impression of looking older than your actual age.
The corners of the mouth do not rise naturally and appear drooped, making the nasolabial folds look deeper and more pronounced.
Even when you are just sitting still, it can give the impression of keeping your mouth tightly closed, which can lead to misunderstandings such as “Are you angry?” or “You look tired.”
When smiling, the teeth do not show clearly, and the smile can appear awkward and restrained, causing a loss of confidence.
Functional concerns
A normal bite allows the upper and lower teeth to interlock like gears, helping you chew food efficiently. However, with retracted incisors, the angle of the front teeth is abnormal, so the function of the anterior teeth in cutting food may be reduced.
Because excessive force is often placed on the muscles around the lips when closing the mouth, this may place a long-term burden on the temporomandibular joint.

In particular, if past treatment for protruding teeth focused only on closing extraction spaces without considering function and aesthetics, the likelihood of retracted incisors becomes very high. Since the teeth and surrounding tissues that have already moved must be restored to a healthy state again, retreatment is much more difficult.
Here Is How Retracted-Incisor Correction Is Carried Out.

The success of retracted-incisor correction depends on how accurately we assess not the visible crown of the tooth, but the tooth root (root) hidden within the jawbone and the alveolar bone surrounding it.
Through 3D-CT imaging, we precisely analyze in millimeters not only the inclination of the roots but also whether there is sufficient alveolar bone thickness to move the teeth outward, and then create a treatment plan.
Without this analysis, it is no exaggeration to say that successful retreatment is impossible.
If retracted-incisor correction is not done properly, it can also affect facial impression.
Therefore, it is most important to thoroughly consult with the medical team about your condition and establish a precise treatment plan.
One-to-One Dedicated Treatment Without Changing the Primary Doctor

Orthodontic treatment should continue with the original diagnosis and philosophy of the treating clinician until the very end.
At Smile D Dental Clinic, I, the clinic director and orthodontic specialist with 18 years of experience, personally stay with each patient throughout the journey—from consultation to the day the appliance is removed and through retention care—without changing the orthodontic specialist, taking responsibility every step of the way.
In addition, specialists with more than 10 years of experience work together in collaboration to strive for more successful orthodontic treatment.
Transparent Fee Disclosure

Orthodontic treatment, whether it is the first treatment or retreatment, can naturally feel financially burdensome.
However, Smile D aims to reduce that burden for patients through a transparent pricing policy.
- The cost may vary depending on the patient’s oral condition, the type of appliance, and other factors, and during consultation
we provide guidance while keeping all possibilities open.
Limiting Orthodontic Appointments to 30 New Patients per Month

Orthodontic treatment, especially retracted-incisor retreatment that must also consider bone conditions, requires a precise monthly process of tracking the minute movement of the teeth and revising the plan.
The reason we limit new patients to 30 per month is to focus fully on each patient’s subtle changes and communicate sufficiently, rather than providing mechanical treatment during this important monthly treatment process.
Time to Regain a Natural Smile

A sunken-lips appearance may not be your true natural look. Don’t miss the golden time,
and with Smile D Dental Clinic—Naver rating 4.82 = satisfaction 96.4%—we hope you can regain the natural smile and confidence you lost due to incorrect orthodontic treatment.
Thank you.
