Kör whitening
Kör whitening uses peroxide gel to lighten natural teeth after a dentist checks whether whitening suits you.
The short answer
Kör whitening refers to a professional whitening system using peroxide gel with custom trays or a dental-office protocol; the dentist first checks whether whitening suits your teeth.
What should the dentist check before Kör whitening?
Have the dentist record your current shade and inspect for decay, cracks, gum recession, and defective restorations. The plan may use custom trays, controlled gel contact, and instructions to reduce gel touching the gums.
How should you prepare before starting Kör whitening?
Seek an examination before whitening if you have untreated pain, cavities, bleeding gums, exposed roots, or a single dark tooth. Stop and contact the dental team if marked gum irritation or persistent tooth pain develops.
When should you delay Kör whitening and seek dental care?
Ask which Kör formulation and delivery method are planned, whether restorations will need replacement for shade matching, and how sensitivity will be handled. Ask how the final shade will be assessed.
What should you ask about your Kör whitening plan?
