Is kor whitening better than zoom
KöR and Zoom use peroxide whitening in different delivery systems, so the better choice depends on stains, sensitivity, and dental findings.
The short answer
KöR and Zoom use peroxide whitening in different delivery systems, so the better choice depends on stains, sensitivity, and dental findings. KöR commonly centres on a dentist-made tray and scheduled home applications, while Zoom is commonly delivered as an in-office light-assisted system.
How do the two peroxide whitening approaches differ?
Both approaches rely on peroxide reaching pigmented molecules in natural enamel and dentin. A light or lamp does not whiten crowns, veneers, or fillings, and neither system corrects decay or gum disease.
How can you choose between the available whitening systems?
Have the dentist identify the stain type, record a shade, check restorations, and assess sensitivity before selecting the system. Discuss tray fit, application schedule, isolation of the gums, and what happens if sensitivity interrupts treatment.
When should dental problems be treated before whitening?
Obtain an examination before either system if you have pain, untreated decay, cracked teeth, gum recession, or bleeding. Stop whitening and contact the dental team for persistent pain, gum burns, or swelling.
What should you ask when comparing whitening systems?
Ask which system matches your stain and sensitivity pattern, how natural teeth will be isolated, and how the final shade will be maintained. Ask whether visible restorations need replacement for a colour match.
Frequently asked questions
Does the light whiten fillings?
No. A light cannot change the colour of composite, porcelain, crowns, or veneers.
Which system causes less sensitivity?
Sensitivity depends on concentration, exposure, tooth condition, and individual response, so the plan must be tailored.
