Developed by internationally renowned cosmetic dentist and bleaching expert, Dr. Rod Kurthy, the KöR Whitening System is used by thousands of dentists worldwide and is widely considered to be the most reliable and effective whitening system ever developed.
The KöR Whitening system has proven to consistently produce whiter, brighter smiles in patients. In fact, the KöR system is so effective, it is the only recognized whitening system that whitens tetracycline-stained (dark) teeth in a short time (previously considered impossible). And due to its advanced formulation and continuous refrigeration of the whitening gels, there’s little to no sensitivity during the whitening process.

A key to the effectiveness of the KöR system are the unique KöR-Seal™ trays used for at-home whitening. These trays are made of thin clear flexible vinyl and are carefully fabricated to fit precisely to your teeth. Most patients find these trays extremely comfortable to wear and have no trouble sleeping with them. These unique KöR-Seal trays allow room for bleaching gel to be kept in contact with the teeth, and they seal at the gum line so that gel is not diluted, or washed away, by saliva. This ensures the maximum whitening results.
And the KöR Whitening System is perfect for patients of all ages, including teenagers and baby boomers.
The KöR Whitening System works by restoring your teeth’s ability to absorb oxygen. The oxygen from KöR’s whitening gel is absorbed deeply into your teeth, dissolving all stain molecules, leaving your teeth incredibly white. And KöR Whitening products have been clinically proven safe on thousands of patients without harming teeth or gums.
The KöR Whitening System is a safe, effective, and convenient cosmetic dentistry procedure that can improve the appearance of teeth to restore self-esteem and self-confidence.
So, if you’re too embarrassed to smile, have dark-stained teeth, or just simply want a whiter smile, the KöR Whitening System offers the best in whitening science, and is by far the best whitening system available today.

Yes, KOR Whitening is safe and effective for most patients looking to achieve a brighter smile. However, it's best to consult with our dental team to determine if you are a good candidate based on your dental history and expectations.
Most patients experience little to no sensitivity during or after the treatment. Our team takes precautions to minimize discomfort, and any sensitivity typically resolves within a few days post-treatment.
With proper oral hygiene and periodic touch-ups, KOR Whitening results can last indefinitely. Avoiding foods and habits that stain teeth and following our aftercare recommendations will help maintain your bright, white smile.
KOR Whitening is professionally administered and offers stronger, longer-lasting results compared to over-the-counter products. Its specialized formula and custom-fit trays ensure even whitening and minimal sensitivity, delivering a superior whitening experience.
KöR Whitening can noticeably lighten tooth colour, including some deeper stains, when it is prescribed and monitored by a dentist. Results vary based on the cause of discolouration, enamel condition, and how closely the treatment instructions are followed.
KöR Whitening typically costs more because it involves custom-fitted trays, professionally supplied whitening gel, and dentist supervision throughout treatment. These steps allow the dentist to control gel strength, minimise sensitivity, and tailor the process to the patient’s teeth.
When KöR Whitening is performed under a dentist’s supervision, it is generally considered safe for enamel. Dentists assess tooth structure and existing sensitivity before treatment and may adjust the protocol to protect enamel and gum tissue.
Yellow or stained teeth can often become lighter with professional whitening, depending on the cause of discolouration. Teeth affected by ageing, food, beverages, or smoking usually respond better to stains caused by internal tooth changes.
KöR Whitening is often selected by dentists for patients with more persistent staining because it allows longer contact time under controlled conditions. Effectiveness depends on stain type, tooth health, and individual response rather than the system alone.
Teeth whitening is usually seen as a cosmetic treatment, which means that most dental insurance plans typically do not cover it. Dentists review treatment goals and costs with patients before starting care. At Polish Dentistry in Houston, TX, this conversation happens as part of the consultation process.
