The short answer

Protruding front teeth and open bite are two bite patterns that clear aligners can sometimes improve, and sometimes cannot. Habits such as tongue thrusting can play a part, and skeletal causes may need braces or a wider plan. Invisalign is published at ₩2.5M to ₩7M and fixed braces at ₩2.8M to ₩3.6M. Your dentist checks the cause first, then explains what is realistic for your case.

What These Bite Patterns Are

Protruding teeth, sometimes called an overjet, mean the upper front teeth stick out in front of the lower teeth. An open bite means the front teeth do not meet when you close, leaving a gap you can see between upper and lower teeth.

Both can affect appearance, and an open bite can make biting through food with the front teeth harder. Neither always needs treatment, so an examination comes first.

Some people also notice that their lips do not close easily at rest, or that certain sounds such as s are affected. These can be linked to the bite, but they can have other causes, so mention them to your dentist rather than assuming.

Seeing the pattern in photos and on a scan helps you understand it. Ask your dentist to show you where the front teeth meet and where they do not, so you can judge how much it matters to you.

  • Protrusion: upper front teeth sit forward of the lower teeth.
  • Open bite: front teeth do not touch when the back teeth meet.
  • Both can occur together, and both vary from mild to marked.
Protruding Teeth & Open Bite: how the treatment is planned

What Causes Them

Causes include thumb sucking in childhood, a tongue that pushes forward when swallowing, mouth breathing and the way the jaws grew. In adults, the cause is often a mix.

If a habit is part of the cause, treating the teeth alone may not hold. Your dentist may suggest ways to address the habit alongside orthodontic treatment.

Jaw growth is the factor patients can least change. When the upper jaw sits forward or the lower jaw is set back, the front teeth may look protruding even though the teeth themselves are in a normal position relative to the jaw. This is a skeletal pattern, and it limits what aligners alone can do.

Care for Taepyeong, Moran, Sujin and Bundang Patients

The clinic is by Taepyeong Station Exit 5 in Sujin-dong, Seongnam, serving people from Taepyeong, Moran, Sujin, Sinheung, Wirye and Bundang.

This kind of treatment needs regular follow-up. Opening hours are Mon–Wed 09:30–20:30, Thu 09:30–19:00, Fri 09:30–18:30 and Sat 09:30–13:00, with no lunch break; the clinic is closed on Sundays and open on public holidays. Use a map app to plan your route; we do not state travel times.

English consultation is available, so you can describe your habits and concerns, ask questions and understand the limits of each option. If you may leave Korea during treatment, say so early so the plan can be realistic.

Treatment Options

The right tool depends on whether the problem is in the teeth, the habit or the jaw. Your dentist may suggest one option or a combination.

Mild to moderate cases

Clear aligners

Can retract front teeth or close some open bites in suitable cases.

More control

Braces

Metal, combination, ceramic or Clippy-C self-ligating braces offer stronger control for harder movements.

When jaw is involved

Combined plan

Skeletal open bites may call for a wider plan, which your dentist will explain, including when a specialist opinion is sensible.

Alongside treatment

Habit support

Tongue habits and mouth breathing can undo results, so they are discussed as part of the plan.

Aligners or Braces?

Neither is simply better. The question is which one gives enough control for your bite and which one you can live with for the length of treatment.

WornRemovable, wear as instructedFixed to teeth

CleaningRemove to cleanNeeds care around brackets
Published fee₩2.5M–₩7M₩2.8M–₩3.6M

Published non-covered fees; VAT may apply. Your dentist confirms what suits your case.

Limits and Alternatives

Aligners cannot change the underlying jaw structure. If your bite pattern comes from the jaw, aligners might improve the look of the teeth but not remove the cause.

Your dentist will tell you where the limits are for your case, and we do not guarantee outcomes. The result depends on your case and how closely you follow the plan.

Teeth can drift back after treatment, especially if a tongue habit remains. Retainers are essential, and the clinic lists fixed retainers at ₩100K to ₩200K and removable retainers at ₩150K to ₩200K.

  • Mild cases: aligners often considered
  • Moderate cases: aligners or braces, depending on control needed
  • Skeletal cases: a wider plan may be needed
  • Habit present: address it alongside the teeth

What It Costs

Your dentist confirms which row applies to your plan after examination. Total cost may also include retainers and check-ups.

Crowded, protruding front teeth treated with Invisalign without extractions

Treated by Dr. Hyeonjoon Park

AfterAfter: Crowded, protruding front teeth treated with Invisalign without extractions
Front view before and after treatment
BeforeBefore: Crowded, protruding front teeth treated with Invisalign without extractions
AfterAfter: Crowded, protruding front teeth treated with Invisalign without extractions
Lateral cephalometric X-rays before and after: lip position against the aesthetic line

Why the patient came in

The patient came in for a protruding mouth and crooked teeth. The front teeth were severely crowded and tilted inward, the dental arches were narrow, and the lips were strained when closed. Crowding like this also makes thorough brushing difficult.

What was done

  1. The patient chose Invisalign clear aligners.
  2. A ClinCheck simulation was used to plan the tooth movements and preview the expected result.
  3. The arches were widened to create space for the crowded teeth, so no teeth were extracted.
  4. At the end of treatment the teeth were evenly aligned and the lips sat behind the aesthetic line on the X-ray.

Published with the patient’s consent. Photos and X-rays are from the clinic’s records. Treatment plans and results differ for every patient; only an examination can show what is possible for you. Orthodontic treatment can cause early discomfort, gum inflammation or root resorption. Retainers are needed afterwards to keep the result.

Protruding Teeth & Open Bite: frequently asked questions

Can Invisalign fix protruding teeth?

In suitable mild to moderate cases, aligners can pull the front teeth back. If the cause is the jaw, the effect is limited. Your dentist decides after examination.

Can an open bite close without braces?

Sometimes, with aligners in suitable cases, but not always. Skeletal open bites may need braces or a wider plan.

Does tongue thrust matter?

Yes. A tongue that pushes forward can keep an open bite open or push teeth out again. Habits are discussed alongside treatment.

How much does it cost?

Invisalign is published at ₩2.5M to ₩7M, metal braces at ₩2.8M, combination braces (ceramic upper, metal lower) at ₩3.1M, ceramic braces at ₩3.2M and Clippy-C self-ligating braces at ₩3.6M. Final fees are confirmed at consultation.

When are braces better than aligners?

When stronger control is needed for harder movements. Your dentist explains which suits your bite.

Will I need a retainer?

Yes. Retainers help hold the result. Fixed retainers are published at ₩100K to ₩200K and removable retainers at ₩150K to ₩200K.

Do protruding teeth always need treatment?

No. Some people are happy with their teeth. Treatment is a personal choice, and an examination shows what is possible.

Is English consultation available?

Yes. The clinic states that English-language consultation is available, and you can ask your questions before you visit.
