KöR is a professionally supervised whitening protocol that uses refrigerated, high-potency whitening gels and custom-fitted trays to achieve deep, long-lasting results. The system is designed to restore teeth's natural ability to receive oxygen so the active whitening agents can penetrate and dissolve internal stains rather than just treating surface discoloration. KöR protocols combine at-home overnight application with optional in-office procedures for cases that need additional activation.

The technology emphasizes product stability and delivery, which helps preserve gel potency from manufacture to application and allows sustained contact with tooth enamel during treatment. This approach is why KöR is often chosen for difficult staining cases that respond poorly to standard whitening methods. Your dentist will determine the appropriate KöR protocol based on the nature and severity of your staining.

KöR differs in three principal ways: continuous refrigeration of the gels, custom-sealed trays that limit contamination, and a focus on deep bleaching that targets intrinsic stains. Continuous refrigeration preserves the gel's strength until use, while KöR-Seal trays are designed to block saliva and fluids that would otherwise neutralize the whitening agent. Together these features support prolonged, effective exposure to the active ingredient during overnight wear.

Unlike some in-office whitening systems that rely solely on brief, high-intensity sessions, KöR typically combines controlled at-home overnight bleaching with targeted in-office enhancement when needed. This hybrid model allows for thorough stain penetration with minimized sensitivity and predictable, stable outcomes over time. Your dental team can explain how KöR compares to other options given your specific dental history.

Good candidates are healthy adults with realistic expectations who want to address tooth discoloration from aging, dietary habits, tobacco use, trauma, medication, or developmental staining. A dental exam is essential before treatment to confirm that there are no untreated cavities, active gum disease, or loose restorations that could interfere with safe whitening. Patients with significant restorative work should discuss how whitening may affect the appearance of natural teeth versus crowns or veneers.

KöR can be an excellent option for patients who have previously had limited success with over-the-counter products or who require a deeper approach for intrinsic stains. Certain medical conditions, active oral infections, or pregnancy and breastfeeding are common contraindications, so candidacy is always determined on an individual basis. Your dentist will review your medical and dental history during the consultation to recommend the safest and most effective plan.

KöR is one of the treatments clinically recognized for producing meaningful improvement in deep intrinsic stains, including those caused by tetracycline exposure. The system's formulation and delivery method enable the whitening agent to reach stains located within the tooth structure, which is why patients with stubborn discoloration often see better results than with surface-only therapies. Results vary by individual and depend on factors such as the age and severity of the staining.

Complete elimination of very deep stains is not guaranteed, but many patients experience significant lightening that improves the overall appearance of their smile. In some cases, KöR can be combined with restorative options to achieve the desired esthetic outcome after whitening has maximized the natural tooth shade. Your dentist will set realistic expectations and outline any follow-up restorative considerations if needed.

The KöR process typically begins with an exam, dental cleaning if needed, and impressions to fabricate custom KöR-Seal trays that fit precisely over your teeth. You will receive refrigerated whitening gels and instructions for overnight wear, with the treatment duration tailored to your goals and sensitivity profile. Some protocols include a single in-office session to boost results after the prescribed at-home phase.

Throughout treatment, your dentist will monitor progress and adjust the plan if necessary to balance whitening intensity with comfort. Patients are advised to follow post-treatment maintenance recommendations, which may include periodic touch-ups with the provided trays and gels. Proper home care and routine dental visits help preserve the outcome over time.

Tooth sensitivity with KöR is generally minimal compared with many traditional whitening methods because the gels do not rely on harsh stabilizers and often include desensitizing components. The custom KöR-Seal trays also reduce exposure of soft tissues and help maintain a steady, prolonged application, which can lessen spikes in sensitivity. Nevertheless, individual responses vary and some patients may experience transient sensitivity during or shortly after treatment.

If sensitivity occurs, your dental team can recommend measures such as adjusting wear time, using desensitizing toothpaste, or applying in-office desensitizing agents to improve comfort. Most sensitivity diminishes quickly once active treatment stops or when modifications are made. Your dentist will provide guidance to minimize discomfort while maintaining effective whitening progress.

KöR is designed to produce long-lasting whitening by addressing deeper stains, and many patients enjoy durable improvements when they follow recommended maintenance habits. Results can be prolonged by avoiding or reducing staining behaviors such as smoking and frequent consumption of dark beverages, and by practicing consistent oral hygiene. The natural aging process and lifestyle exposures will gradually affect tooth shade over years, which is normal.

Maintenance often involves occasional at-home touch-up sessions with the provided trays and gel or periodic short follow-up treatments as advised by your dentist. Regular dental cleanings and checkups also help maintain the brightness and overall oral health that support a lasting result. Your dentist will recommend a maintenance schedule tailored to how your teeth respond.

KöR whitening safely whitens natural tooth enamel, but it does not change the color of existing dental restorations such as crowns, veneers, bridges, or composite fillings. Because restorations remain the same shade, clinicians typically recommend whitening natural teeth first and then evaluating whether replacement or adjustment of restorations is necessary to match the new tooth color. This sequencing helps achieve a harmonious, esthetic outcome.

Your dentist will review any restorations during the initial evaluation and advise on the best approach, which may include planning restorative work after whitening if color matching is a concern. For patients with many visible restorations, the dentist will explain realistic expectations and alternative options to improve overall smile appearance. Safety considerations will always be addressed during treatment planning.

Preparation begins with a comprehensive dental exam and completion of any necessary preventive or restorative care, such as treating cavities or addressing gum disease, so the whitening can be performed safely and effectively. A professional cleaning prior to treatment removes surface deposits that can interfere with uniform whitening and gives the dental team a clear baseline for shade assessment. It is also helpful to stop smoking and reduce intake of staining foods and drinks in the weeks leading up to treatment.

Your dentist will provide specific pre-treatment instructions, including how to care for your trays and the refrigerated gels, and will discuss any medical considerations that could affect candidacy. If you take medications or have health conditions that may influence outcomes, disclose them during the consultation so your provider can adapt the plan. Clear communication ensures a safer, more predictable whitening experience.
