Teeth Whitening

A bright, white smile makes you look younger, healthier, and more confident. At J. Dennis Lewis Dentistry, we specialize in professional teeth whitening in Brea, delivering dramatic results you can’t achieve with drugstore products. Dr. J. Dennis Lewis uses the best-researched, most effective KöR Whitening Deep Bleaching System to transform even the most stubborn stains into brilliant, radiant smiles.

Your teeth are constantly exposed to staining agents like coffee, tea, red wine, and certain foods. Over time, these substances penetrate deep into your enamel, creating discoloration that regular brushing can’t touch. Age also naturally yellows teeth as enamel thins and the darker layer underneath shows through more prominently.

Why KöR Whitening Changes Everything

Not all whitening systems deliver equal results. Dr. J. Dennis Lewis chose KöR Whitening because it represents today’s most effective whitening technology. This advanced system can whiten teeth that other methods simply can’t touch, including tetracycline-stained teeth that dentists once considered impossible to bleach.

KöR Whitening works differently from conventional whitening products. The system uses specially formulated gels that remain potent and effective throughout treatment. Most whitening products begin degrading when manufactured, losing strength before reaching your teeth. KöR gels stay refrigerated from creation to application, maintaining full potency for maximum effectiveness.

The science behind KöR focuses on restoring your teeth’s ability to absorb oxygen. The whitening gel penetrates deeply into your enamel, breaking apart stain molecules at the molecular level. This deep bleaching process produces natural results, never fake or overly white, and lasts significantly longer than other whitening treatments.

The KöR Whitening Process

Your teeth whitening in Brea journey begins with a comprehensive consultation. Dr. Lewis examines your teeth to ensure they’re healthy enough for whitening and discusses your goals to determine which KöR system best suits your needs. We take impressions to create custom-fitted trays that fit your teeth perfectly, ensuring even whitening coverage and preventing gel from irritating your gums.

The KöR Deep Bleaching System combines at-home and in-office treatments for optimal results. You’ll wear your custom trays with the specially formulated whitening gel while you sleep for two weeks. Overnight application maximizes the gel’s effectiveness because your mouth produces less saliva during sleep, allowing the whitening agents to work undisturbed for hours.

After your at-home treatment phase, you return to our office for a final in-office session. Dr. J. Dennis Lewis applies a powerful whitening gel and uses advanced techniques to activate it, delivering that final boost that takes your smile from bright to absolutely stunning. The entire in-office appointment takes about an hour, and you’ll see immediate results that continue improving over the following days.

Dramatic Results That Last

KöR Whitening delivers the most dramatic, longest-lasting results in professional teeth whitening. While other systems might lighten your teeth a few shades, KöR can brighten smiles by ten shades or more. The deep bleaching technology reaches stains that surface-level treatments miss, creating transformations that truly wow.

These results last for years, not weeks or months. With occasional at-home maintenance treatments using your custom trays, you can keep your brilliant smile indefinitely. Dr. Lewis provides everything you need for touch-ups, making it easy to maintain your investment.

Perfect for Sensitive Teeth

Many people avoid whitening because they’ve experienced sensitivity with other products. KöR Whitening addresses this concern head-on. The system includes desensitizing agents that minimize discomfort, and the custom trays ensure gel stays on your teeth rather than touching sensitive gum tissue.

Most KöR patients report little to no sensitivity during treatment. If you do experience any discomfort, it’s typically mild and temporary, fading quickly after treatment ends. Dr. J. Dennis Lewis can also recommend additional desensitizing products if you have particularly sensitive teeth, ensuring your whitening experience remains comfortable from start to finish.

Beyond Coffee Stains

KöR Whitening excels at removing the toughest stains that other systems can’t handle. Coffee and wine stains disappear easily, but this powerful system also tackles:

  • Tobacco stains from smoking or chewing
  • Medication-related discoloration, including tetracycline staining
  • Fluorosis stains from excessive fluoride exposure
  • Age-related yellowing
  • Stains from trauma or root canal treatment

Even if other whitening treatments have failed you in the past, KöR Whitening in Brea might deliver the results you’ve been seeking. The system’s unique approach to deep bleaching reaches stains that other products cannot access.

Professional Whitening vs. Store-Bought Products

You might wonder why professional whitening costs more than drugstore strips or trays. The difference in results speaks for itself. Over-the-counter products use lower concentrations of whitening agents and generic trays that don’t fit properly. They might lighten surface stains slightly, but can’t deliver the dramatic, even results that professional treatment provides.

Professional whitening also protects your oral health. Dr. Lewis ensures your teeth and gums are healthy before treatment begins. Custom trays fit precisely, preventing gel from irritating your gums or being swallowed. The controlled process minimizes sensitivity while maximizing results, giving you a safe, effective whitening experience.

Quick In-Office Options

While KöR Deep Bleaching provides the most dramatic and long-lasting results, we understand some patients need faster solutions. Our teeth whitening in Brea also includes in-office-only treatments for special occasions. These single-visit treatments brighten your smile several shades in about an hour, perfect when you need quick results for an upcoming wedding, reunion, or important event.

Investment in Your Confidence

A bright, white smile affects how others perceive you and your feelings about yourself. Studies show that people with whiter teeth appear more successful, trustworthy, and attractive. More importantly, when you feel confident about your smile, you smile more often—and smiling has proven benefits for your mood, stress levels, and social connections.

Dr. J. Dennis Lewis and our team make professional whitening accessible with flexible payment options. Professional whitening represents an excellent value when you consider how long KöR results last compared to the ongoing cost of drugstore products that deliver minimal results.
