KöR Whitening is designed around a simple principle: deliver active oxygen into the tooth where stains live, rather than only treating surface discoloration. The gels used in the KöR system are formulated and handled in a way that improves penetration into the enamel and dentin. That means brown, yellow, and even some stubborn intrinsic stains are targeted where they form, producing more thorough and even lightening.
Unlike over-the-counter strips or diluted office gels, KöR’s approach emphasizes product integrity and delivery. From manufacturing through storage, the system preserves potency so the peroxide molecules are at their most effective when applied. This focus on maximizing active ingredients, combined with custom-fitted trays, improves contact between gel and tooth for a predictable response.
Patients often notice that KöR doesn’t just brighten isolated teeth — it lifts the overall shade with fewer blotchy results. Because the system works with the tooth’s internal chemistry, the outcome tends to be uniform across the smile rather than spotty, which contributes to a more natural and attractive appearance.
When clinicians describe KöR results as long-lasting, they’re referring to the way the system removes or alters stain molecules deep within the tooth structure. By addressing intrinsic discoloration (stains inside the tooth), KöR reduces the tooth’s capacity to recollect pigments that cause visible darkening. That foundational change is what distinguishes lasting improvement from temporary brightening.
“Permanent” in this context does not mean teeth will never darken again, but rather that the teeth have been effectively restored to a cleaner baseline that resists re-staining. Lifestyle factors — like coffee, tea, red wine, and tobacco — can gradually tint teeth over time. The benefit of KöR is that with minimal, occasional touch-up care at home, many patients maintain their improved shade for years rather than months.
Routine maintenance is straightforward and noninvasive: intermittent overnight wear of the custom trays with a maintenance gel can preserve results. Because the primary whitening action has already altered staining within the enamel and dentin, these periodic refreshes are typically effective and simple to incorporate into an oral-care routine.
Safety and patient comfort are central to KöR’s design. The whitening gels used in the system are clinically studied and formulated to minimize common side effects such as sensitivity. One contributing factor is the way the gels are handled — refrigerated storage and careful preparation reduce the need for chemical stabilizers that can irritate tooth nerves and soft tissues.
Most patients report mild or no sensitivity with KöR compared with traditional high-concentration treatments. When sensitivity does occur, it is generally short-lived and manageable with standard at-home strategies recommended by dental professionals. Additionally, the system’s emphasis on custom-fit trays helps limit gel contact with the gums, further reducing the chance of irritation.
Clinically, KöR is considered safe for a broad range of patients when used as directed. Your dental provider will review your dental health and treatment goals to confirm suitability. Those with extensive restorations or specific dental conditions receive a tailored recommendation so whitening is performed thoughtfully and safely.
The KöR program typically combines a short, comfortable in-office component with a home-based phase that fits into everyday life. The in-office visit(s) prepare and optimize the teeth for the at-home therapy, while custom impressions are taken to create ultra-comfortable KöR-Seal™ trays. These thin, form-fitting trays hold the whitening gel against the teeth throughout the overnight wear period.
Most patients wear their KöR-Seal trays while they sleep for approximately two weeks, although specific protocols can vary depending on initial staining and the selected KöR system. The trays are engineered to remain secure during sleep and to trap the gel inside so it does not pool or leak onto the gums, supporting both effectiveness and comfort.
Because the regimen happens largely overnight, it is easy to maintain with a busy schedule. Brief office appointments for monitoring or single-session boosts are available when recommended, but the core work occurs in a series of nightly applications that are typically discreet and low hassle.
KöR can produce dramatic improvements, but outcomes depend on individual factors such as the type and depth of staining, age of the teeth, and oral habits. Teeth that are younger and less affected by deep intrinsic stains typically respond more quickly, while advanced discoloration — including certain medication-related stains — may require a carefully managed plan to reach an ideal shade.
One important point: restorations such as crowns, veneers, and composite fillings do not change color with whitening gels. If you have visible restorations on your front teeth, your clinician will discuss potential adjustments or replacements to achieve a harmonious shade across natural teeth and prosthetics after whitening is complete.
To protect your investment in a brighter smile, follow-up care is simple: occasional overnight maintenance with the KöR trays and mindful avoidance or moderation of heavy staining habits keep results looking fresh. The practice can recommend a tailored maintenance schedule and support you with the right at-home products to sustain your improved shade.

KöR Whitening is a professional bleaching system that delivers active oxygen into enamel and dentin to address both surface and intrinsic stains. The protocol combines in-office preparation, custom-fitted trays and specially formulated gels that are handled to preserve peroxide potency until application. This focus on product integrity and delivery helps produce more uniform lightening than many over-the-counter products.
The system’s custom trays and potent gels improve contact between the whitening agent and tooth structure, reducing the blotchy results sometimes seen with strips or diluted formulations. Because KöR targets stain molecules inside the tooth, it often lifts overall shade more consistently across the smile. Clinician oversight ensures the treatment plan and wear schedule are tailored to each patient’s needs and expectations.
KöR works by delivering active oxygen molecules that diffuse into enamel and dentin where intrinsic stains reside, altering or removing stain compounds at their source. The gels are formulated and stored to maintain maximum activity so that peroxide molecules remain effective when applied in the custom trays. This molecular-level action contrasts with treatments that primarily affect only surface discoloration.
Custom impressions produce ultra-thin, well-sealed trays that optimize gel contact and prevent pooling on the gums, which enhances penetration into the tooth. The overnight wear protocol used with many KöR systems provides extended contact time, increasing the opportunity for active oxygen to reach deeper stain sites. As a result, patients often see lightening that appears more integrated and even across treated teeth.
Clinical studies and practitioner experience indicate KöR is safe when used under professional supervision, and the system includes features designed to reduce sensitivity. Refrigerated storage and careful handling of the gels limit the need for chemical stabilizers that can irritate tooth nerves and soft tissues. Custom trays also reduce gum exposure to gel, lowering the chance of soft-tissue irritation.
Many patients report minimal or no sensitivity compared with some traditional in-office high-concentration treatments, and any transient sensitivity is generally manageable with standard at-home measures recommended by dental professionals. Your clinician will assess tooth and gum health before treatment and recommend desensitizing strategies if you have a history of sensitivity. Thoughtful monitoring during the treatment sequence helps keep the procedure comfortable and safe for each patient.
The KöR program typically begins with a short in-office visit to prepare teeth and take impressions for custom trays, followed by a home-based overnight whitening phase. In-office steps optimize tooth surfaces and ensure impressions capture precise anatomy for ultra-comfortable trays that hold the gel in place. The home phase usually involves wearing the KöR-Seal trays during sleep for a prescribed number of nights to allow extended gel contact.
Because most of the active whitening occurs overnight, the regimen fits easily into daily life and requires only brief follow-up appointments for monitoring or adjustments. Trays are engineered to prevent leaking and to keep the gel against teeth rather than gums, supporting both effectiveness and comfort. Your clinician will provide clear instructions for tray care, gel use and the expected treatment timeline based on your individual staining pattern.
KöR is described as long-lasting because it modifies or removes stain molecules within the tooth, creating a cleaner baseline that resists re-staining better than treatments that only affect the surface. "Permanent" in professional discussions means the intrinsic stain reduction endures, but it does not guarantee teeth will never darken again. Lifestyle factors such as consumption of coffee, tea, red wine or tobacco can gradually tint teeth over time.
Maintenance is straightforward and typically involves intermittent overnight use of the custom trays with a maintenance gel to refresh shade when needed. Because the primary whitening has altered staining within enamel and dentin, these occasional touch-ups are often effective and simple to incorporate. Your dental team can recommend an individualized maintenance schedule to help preserve results for years rather than months.
Good candidates are adults with natural teeth who have extrinsic or intrinsic discoloration and who maintain generally healthy gums and enamel. KöR can be effective for a variety of stains, including some deeper intrinsic discolorations that do not respond well to surface-only treatments. A dental exam is important to confirm there are no untreated cavities, gum disease or other conditions that should be addressed before whitening.
Certain patients, such as those with extensive restorations on front teeth or untreated dental disease, may require an alternative or a carefully staged plan that includes restorative work. Pregnant or breastfeeding patients and some individuals with specific dental conditions should consult their clinician before beginning whitening. Your provider will review your medical and dental history and recommend the safest, most appropriate approach for your smile.
Intrinsic stains, including those related to certain medications, form within enamel and dentin and are often more resistant to surface-level treatments. KöR’s approach is designed to reach deeper stain molecules by preserving peroxide potency and using prolonged contact under custom trays, which increases the potential for change within the tooth structure. While outcomes vary by the type and age of the stain, KöR often achieves improvement where other methods have been less effective.
For some medication-related stains, a carefully managed treatment plan with realistic expectations is essential; multiple cycles or combined restorative options may be discussed if needed. Your clinician will evaluate the nature of the discoloration and explain likely results, possible timelines and any supplemental procedures that could enhance aesthetics. Thoughtful planning helps ensure a balanced, natural-looking outcome tailored to each patient’s situation.
No, dental restorations such as crowns, veneers and composite fillings do not whiten with bleaching gels because they are made of materials that do not respond to peroxide the way natural tooth structure does. This means restorations that are visible when you smile may need to be evaluated to match the new shade of natural teeth after whitening is complete. Your clinician will discuss sequencing options to achieve a harmonious appearance across both natural teeth and restorations.
If you have existing restorations on your front teeth, your provider may recommend completing whitening first and then assessing whether any restorations require replacement or modification to match the improved tooth shade. Planning restorations after whitening helps avoid color mismatch and creates a more uniform smile. The practice will outline restorative considerations as part of your personalized treatment plan.
To protect whitening results, practice consistent oral hygiene, limit frequent exposure to staining substances and use the maintenance protocol recommended by your clinician. Occasional overnight refreshes using the custom KöR trays with maintenance gel are effective for many patients and are easy to fit into a regular routine. Avoiding or moderating habits like heavy coffee, red wine and tobacco will also help extend the appearance of your improved shade.
Regular dental checkups and professional cleanings support long-term results by removing surface deposits that can dull color and by identifying any changes that might affect appearance. Your dental team can supply or prescribe appropriate at-home products and advise on timing for touch-ups based on your personal habits and response to treatment. A tailored maintenance plan keeps your smile looking its best while minimizing the need for extensive retreatment.
The most reliable way to determine suitability is a consultation and exam so a clinician can assess staining type, tooth and gum health, and any existing restorations. During that visit the provider will review your dental history, answer questions about expected outcomes and outline a treatment and maintenance plan that aligns with your goals. Clinical photos or shade references may be used to document starting color and anticipated improvement.
