The short answer

Crowded teeth do not have enough room to sit in a neat line. Clear aligners can help with many cases by creating space in one of three ways: gentle slimming between teeth, widening the arch, or, in some cases, removing teeth. Your dentist chooses the approach after examining you, and tells you honestly when braces would suit better.

Why Teeth Become Crowded

Teeth crowd when the jaw is small for the teeth, when baby teeth were lost early, or when teeth shift over time. Crowding can make cleaning harder, because floss and brushes struggle to reach overlapping surfaces.

Some people are happy to leave mild crowding. Others want straight teeth for comfort, cleaning or appearance. Either choice is valid, and an examination shows what is possible.

Adults sometimes notice crowding increase after earlier braces, because teeth drift without a retainer. Wisdom teeth are often blamed, but the dentist judges that from your own X-rays rather than assuming.

Crowding is a space problem. Every treatment that straightens crowded teeth has to find that space somewhere, and the three routes below are how it is usually done.

Ways to Make Room

Which method applies depends on how much space you need and on your gums, bone and bite.

IPR is done in small amounts at planned stages, and your dentist will explain which teeth are involved. It is not suitable for every mouth, for example where teeth are small or enamel is thin.

Expansion tips teeth outward, and the gum and bone on the outside of the teeth limit how far that is wise. It can look fuller or flatter depending on the case, so ask to see the planned result.

Often a plan combines more than one method in modest amounts.

Slimming between teeth

IPR

A very small amount of enamel is polished from between teeth to create a little space. Your dentist decides if it is suitable.

Widening the arch

Expansion

Teeth are moved outward slightly, which suits some cases and not others.

Removing a tooth

Extraction

Sometimes used in significant crowding. It is a decision made with you after examination.

Crowding Treatment for Taepyeong, Moran, Sujin and Bundang Patients

The clinic is by Taepyeong Station Exit 5 in Sujin-dong, Seongnam, serving Taepyeong, Moran, Sujin, Sinheung, Wirye and Bundang. Aligner plans need regular check-ups, so an accessible location helps.

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 for your route; we do not state travel times.

Moran and Sujin are on the Line 8 side of the local map, and Moran and Bokjeong appear on the Suin-Bundang Line too, which gives Bundang-side patients a way to plan by subway.

English consultation is available, so you can talk through the options and ask about the plan without a language barrier.

Extraction or Non-Extraction

Some crowded cases can be treated without removing teeth, using IPR and expansion. Others, especially where crowding is severe, may be planned with extraction so the teeth sit stably.

Your dentist will explain why one route is recommended and what the other would involve. If you prefer to avoid extraction, say so at the start and ask what limits that places on the result.

Neither route is automatically better. Squeezing very crowded teeth into too little space can leave them tilted or the gums thin, while removing teeth you could have kept is an irreversible choice. A careful discussion is worth the time.

How the Plan Is Made

We do not give a fixed duration, because the time depends on the amount of crowding and how closely the plan is followed.

Before starting, gum disease and cavities should be treated, as moving teeth with active problems can make them worse. If you need a cleaning first, insurance-covered scaling follows national health insurance rules, and additional (non-covered) scaling is published at ₩50,000.

Examination

Your dentist checks your teeth, gums and bite.

Records

Scans and images are taken for planning.

Proposal

You see the planned movement, whether IPR or extraction is part of it, and the price range.

Treatment

You wear aligners as directed and attend check-ups.

Retention

Retainers help prevent teeth drifting back.

What It Costs

Severe crowding is more likely to sit toward the upper end of Invisalign. Tooth removal, if needed, is quoted after examination.

When you ask for a quote, check whether it includes attachments, planned IPR, refinements and retainers, and whether VAT is added. Put the answers in writing.

The clinic states that it supports overseas-insurance paperwork, so keep the plan and receipts together.

OptionPublished price (KRW)
Invisalign₩2.5M to ₩7M
Metal braces₩2.8M
Combination braces (ceramic upper / metal lower)₩3.1M
Ceramic braces₩3.2M
Clippy-C self-ligating braces₩3.6M
Fixed retainer₩100,000 to ₩200,000
Removable retainer₩150,000 to ₩200,000

Prices are the published non-covered price list in Korean won. VAT may apply, and your final figure is confirmed at consultation.

When Braces May Be a Better Fit

Where crowding is severe or teeth must be rotated a lot, fixed braces can offer more control. Your dentist will tell you honestly if aligners would be limited in your case.

Braces also do not depend on how many hours you wear them, which can matter if you know that remembering aligners is hard for you.

Whichever option you choose, retainers matter afterward. Ask at the start how long you will be expected to wear them.

Questions to Ask at Your Consultation

Bring any previous orthodontic records and a list of medicines. Photos of your teeth from before earlier treatment can help the dentist understand how they have changed.

Crowded, protruding front teeth treated with Invisalign without extractions

Treated by Dr. Hyeonjoon Park

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.

Orthodontic treatment can cause early discomfort, gum inflammation or root resorption. Retainers are needed afterwards to keep the result.

Aligners for Crowding: frequently asked questions

Can clear aligners fix crowded teeth?

Often for mild to moderate crowding. Severe cases may need braces. Your dentist will assess.

What is IPR?

Interproximal reduction: polishing a very small amount of enamel between teeth to create space.

Will I need teeth removed?

Not always. It depends on how much space is needed and what your dentist recommends.

How much does it cost?

Invisalign is ₩2.5M to ₩7M and fixed braces ₩2.8M to ₩3.6M on the published list, depending on the type.

Do I need a retainer afterward?

Yes, usually. Retainers help hold the result; fixed retainers are listed from ₩100,000 and removable retainers from ₩150,000.

How long does treatment for crowding take?

It depends on how much crowding you have and how closely you follow the plan. Your dentist gives an estimate after examination.

Is IPR safe for my teeth?

Your dentist decides if it suits you, based on enamel thickness and tooth size. It is done in small, planned amounts.

Can I choose not to have an extraction?

You can state that preference. The dentist will explain what limits that may place on the result.
