The short answer

Professional whitening at The Seoul Dental Clinic is published at ₩385,000, VAT included. A single root-treated tooth that has darkened can be bleached from the inside for ₩165,000 per tooth, VAT included. Whitening works on natural enamel only, and results vary from person to person.

How Professional Whitening Works

Whitening uses a peroxide-based gel to lighten stains held inside the enamel. A dental professional controls the strength, protects your gums and checks that your teeth are suitable. That is the main difference from products bought without any dental guidance.

Before treatment, your dentist looks for cavities, worn areas and gum problems. These can make teeth sensitive during whitening and are better treated first. Scaling can also remove surface stain, which helps the whitening reach the tooth evenly.

It helps to know what whitening cannot do. It lightens natural tooth structure only, so existing crowns, veneers, bonding and fillings keep their colour. If you have visible restorations in the smile zone, your dentist may suggest matching them after whitening so everything blends.

Expectations matter too. Two people can follow the same treatment and finish on different shades, because enamel thickness, the cause of the stain and starting colour all differ.

  • Natural teeth lighten; crowns, veneers and fillings do not.
  • Yellow stains tend to respond better than grey ones.
  • The final shade depends on your starting colour and your enamel.
  • Tell your dentist about allergies and any history of sensitive teeth.

Teeth Whitening for Taepyeong, Moran, Sujin and Bundang Residents

The clinic is in Sujin-dong, Sujeong-gu, Seongnam, at Taepyeong Station Exit 5. Residents of Moran, Sujin, Sinheung and Gachon, and visitors from Bundang or Seoul, can combine whitening with a check-up and cleaning in the same trip.

The clinic is open Monday to Wednesday 09:30–20:30, Thursday 09:30–19:00, Friday 09:30–18:30 and Saturday 09:30–13:00, with no lunch break; it is closed on Sundays and open on public holidays. English consultation is available, so you can raise sensitivity or allergy concerns directly.

If you are preparing for a particular date, such as a trip home or an event, mention it when you book. The dentist can tell you whether a cleaning or other treatment should come first, so that the order of steps suits your calendar.

Moran and Bokjeong appear on both the Suin-Bundang Line and Line 8, which gives Bundang-side residents more than one way to plan a route. We do not state travel times.

Price

The table shows the published figures. Whitening is a cosmetic treatment, so it is paid privately, and the published cosmetic prices include VAT.

A cleaning before whitening is common advice. Insurance-covered scaling follows national insurance rules, and additional scaling is published at ₩50,000 as a non-covered item. Whether you need it depends on your teeth, which the dentist checks at the start.

If you are comparing quotes elsewhere, ask what each includes, such as examination, a cleaning step and any aftercare product, so the numbers are like for like.

Price list as published; cosmetic prices include VAT. Confirm at consultation.

Whitening After Root Canal

A tooth that has had a root canal can slowly darken, because the inside of the tooth changes colour. Regular outside whitening often does not fix this well. Internal bleaching places the whitening agent inside the tooth and is published at ₩165,000 per tooth, VAT included.

Your dentist will first check on an X-ray that the root filling is sound. Results vary, and in some cases a crown or veneer is the better answer. You will be told which option fits.

Internal bleaching is aimed at one tooth, not a whole smile. If your other teeth are also dull, your dentist may suggest professional whitening on the rest, and the order of the two is worth asking about.

If the tooth has a large old filling or is already weak, covering it may protect it better than bleaching. This is a judgement for the dentist after examination.

Aftercare

What you do in the days after whitening affects how comfortable you are and how the result holds. Your dentist will give instructions specific to you; the steps below are the general pattern.

Sensitivity, if it appears, usually relates to how your teeth respond to the gel. Report it rather than waiting, so the dentist can advise.

First two days

Teeth can pick up stain more easily. Limit coffee, tea, red wine, dark sauces and smoking.

Sensitivity

Mild temporary sensitivity can happen. Use a toothpaste for sensitive teeth and tell your dentist if it is strong or lasts.

Daily care

Brush twice a day and clean between teeth. This helps the result last.

Check-ups

Regular scaling removes new surface stain. Ask your dentist how often to return.

Whitening FAQ

Short answers to common questions are below. Your dentist can confirm what applies to you.

Worth asking at your visit: whether a cleaning should come first, what to do about any visible restorations, how to manage sensitivity, and how often to return for maintenance.

Cosmetic

A darkened front tooth: root canal retreatment, internal whitening and a ceramic crown

Treated by Dr. Hyun Sung Park

BeforeBefore: A darkened front tooth: root canal retreatment, internal whitening and a ceramic crown
AfterAfter: A darkened front tooth: root canal retreatment, internal whitening and a ceramic crown
Front view before and after treatment

Why the patient came in

The patient came in because one upper front tooth had turned dark. The tooth had a root canal treatment from before, and the X-ray showed inflammation at the root tip.

What was done

  1. The root canal treatment was redone. On opening the tooth, dark contaminated material was found inside the canal.
  2. Part of the root filling was removed and a barrier of glass ionomer or resin was placed to keep the whitening agent inside the crown of the tooth.
  3. A whitening agent was sealed inside the tooth and the colour was checked every 4 to 7 days.
  4. After whitening, the shade was matched and an all-ceramic crown was made so that no dark colour shows through.

A tooth whitened from inside can darken again over time. Retreatment and crown preparation can cause temporary sensitivity or discomfort.

Yellow Teeth: What to Check Before Whitening10:07 · The Seoul Dental Clinic on YouTube
What this video covers

The dentists explain that yellowish teeth are not always a whitening problem: surface stains from coffee, tea, wine, curry or smoking, plaque and tartar, enamel wear, and receding gums that expose the darker root can all play a role. They note that brushing harder does not make teeth whiter and can wear the gumline, and that whitening toothpaste mainly helps with surface stains rather than changing the tooth's inner color. Before using any whitening product, they recommend checking for cavities, sensitivity, gum inflammation, recession and existing fillings, crowns or veneers, which do not change color like natural teeth. They also describe how in-office whitening differs from home products, including protecting the gums during treatment.

  • Find the cause of discoloration first: stain, plaque, wear or gum recession
  • Crowns, veneers and resin fillings don't whiten, which can lead to color mismatch
  • Rinsing with water after dark drinks and regular dental visits help limit staining

Teeth Whitening: frequently asked questions

How much does professional whitening cost?

It is published at ₩385,000, VAT included. Internal bleaching of a root-treated tooth is ₩165,000 per tooth. Confirm at consultation.

Is whitening safe for my enamel?

Supervised whitening is generally considered safe for healthy teeth. Your dentist checks your teeth first, since cavities and worn enamel may need treatment beforehand.

Will whitening make crowns or veneers lighter?

No. Only natural tooth structure lightens. If you have restorations at the front, your dentist can discuss matching them.

How long will the result last?

It varies with your diet, smoking and habits. Avoiding strong stains and keeping up cleanings helps the result last.

Can I whiten if I have sensitive teeth?

Often yes, with care, but tell your dentist beforehand. They can adjust the approach or advise waiting if something needs treatment.

Do I need a cleaning before whitening?

Often it is advised, because surface stain and plaque can get in the way. Insurance-covered scaling follows national insurance rules, additional scaling is published at ₩50,000, and your dentist decides if you need it.

Can I whiten while pregnant?

Ask your dentist. Whitening is usually put off during pregnancy, and your dentist can advise on timing.

Is whitening a medical treatment I can claim abroad?

It is cosmetic and paid privately. Ask your insurer whether it covers any part, and ask the clinic for an itemized receipt.
