Teeth Whitening in Gangnam Seoul

Coffee, tea and time can dull your smile. Professional whitening lightens natural teeth safely under a dentist's care.

In short: professional teeth whitening uses a peroxide gel to lighten stains inside the enamel. You can whiten in the clinic (chairside) in one visit, or at home with custom trays over one to two weeks. It suits healthy natural teeth; crowns, veneers and fillings do not change colour.

Understanding whitening

How does teeth whitening work?

Whitening gels release oxygen that breaks down stain molecules in the enamel. Results vary: yellow-brown stains usually respond well, while grey stains respond more slowly.

One visit

Chairside whitening

A stronger gel applied in the clinic, with gums protected.

  • Visible change in one visit
  • Done under a dentist's care
  • Good before an event
At home

Take-home kit

Custom trays and a milder gel worn at home.

  • Gradual results over 1–2 weeks
  • Good for touch-ups later
  • Can follow a chairside session

Is it right for you?

Questions patients ask us

Teeth whitening FAQ

Is teeth whitening safe?
Yes, when supervised by a dentist. The gel lightens stains without removing enamel. Temporary sensitivity is common and usually settles within a few days.
How long do results last?
Results often last many months, depending on diet and smoking. Occasional home touch-ups help keep the shade.
Will whitening change my crowns or veneers?
No. Crowns, veneers and fillings keep their colour, so they may need replacing to match whitened teeth.
How much does teeth whitening cost in Seoul?
Cost depends on your diagnosis, the materials and the number of teeth or visits involved. After your examination we give you a written, itemised quote in English before any treatment begins.
Can I whiten my teeth in one visit?
Yes. Chairside whitening is done in one appointment; a home kit can then help maintain the result.
