Is kor whitening safe
KöR whitening uses peroxide gel, and its risks depend on concentration, tray fit, gum condition, enamel, exposed roots, and untreated dental disease.
The short answer
The system combines a peroxide gel with a delivery tray. Peroxide can pass through enamel and dentine to break down some internal stains, but restorations do not bleach.

What is the direct answer?
What does this question mean?
Have the teeth examined first, use the prescribed tray and gel amount, and report sensitivity rather than increasing or extending treatment. Keep gel off soft tissue.
What can you do next?
Seek care for severe sensitivity, gum ulceration, cavities, cracks, or a dark tooth. Whitening should not mask a disease process or delay restorative treatment.
When should you seek dental care?
Ask which formulation and schedule are intended for you, how exposed dentine will be protected, and whether crowns or fillings need replacement for shade matching.
What should you ask the dentist?
Active agent
