What is KöR Teeth Whitening?
If you have deep stains on your enamel or a yellowed/discolored sheen to your smile, patients and doctors alike often consider KöR the most lasting and effective teeth whitening system available. KöR is distinguished by its scientific chemical formulation — which doesn’t require lights or lasers — and its continuous refrigeration process, which prevents its bleaching agents from deteriorating. KöR is also one of the only professional teeth whitening systems powerful enough to lighten tetracycline stains and other forms of severe discoloration. KöR is further characterized by other stand-out benefits, including:
- Unique desensitization formula designed to reduce teeth sensitivity after whitening
- Capable of treating severe discoloration like tetracycline stains, which are generally resistant to traditional teeth bleaching systems
- Doesn’t require lights or lasers to activate the whitening process
- Breaks down stain molecules to ultra-small, colorless particles, allowing relatively permanent results
For enamel stains that don’t respond to teeth bleaching, Dr. Stein can recommend other effective whitening options, such as porcelain veneers, to conceal the discoloration. Our dentist can develop a unique treatment plan for your needs and goals in person.
Why are My Teeth Yellow?
Yellowing teeth can dim your smile and hurt your confidence. Unfortunately, teeth tend to discolor with age, due to a variety of factors, including consuming or using:
- Coffee and tea
- Red wine
- Tobacco
- Sports drinks
- Certain sauces
- Berries and other foods that cause tooth stains
- Poor dental hygiene
As you get older, the enamel on your teeth will begin to wear down and expose the dark dentin underneath. In elderly adults, brushing, flossing, and using whitening toothpastes are usually not enough to remove deep tooth stains. Professional teeth whitening works best on patients with yellow teeth. It is less effective on patients with brownish teeth, so talk to Dr. Stein about your treatment options before making a decision.
What are the Benefits of Teeth Whitening?
Professional teeth whitening with the KöR system can be a quick, efficient, and painless treatment to amplify your smile. Unlike generic whitening products that only lighten the surfaces of your teeth gradually, treatment with KöR whitening offers:
- Dramatic improvements in the brightness of your smile
- Noticeable results quickly and non-invasively
- Lightening and lifting of deep discoloration that regular brushing and over-the-counter products often cannot address
- A visibly whiter and more vibrant smile by several shades within one appointment
- Boosted self-confidence, encouraging patients to smile more freely
- Greater self-esteem, creating positive impacts to interpersonal and professional relationships
- Safe, customized treatment tailored to your individual needs
Over time, teeth naturally become stained from coffee, tea, red wine, soda, tobacco use, and even certain medications. Teeth whitening provides a conservative cosmetic dentistry solution that does not alter the natural structure of your teeth but can rejuvenate your smile without committing to more extensive dental work.
When performed under the supervision of a cosmetic dentist, whitening treatments are also tailored to your specific needs. The concentration of whitening agents and the duration of treatment are all carefully controlled. This reduces the risk of irritation and uneven results that can sometimes occur with unsupervised or generic, store-bought products.

Over-the-Counter Teeth Whitening vs. Professional Teeth Whitening
There are plenty of over-the-counter options for whitening your teeth, such as:
- Whitening toothpaste
- Whitening strips
- Whitening mouthwash
- Activated charcoal
- At-home whitening kits
While these solutions may seem convenient on paper, they are not nearly as effective as in-office teeth whitening treatments, which can deliver fast and immediate results. Furthermore, in-office whitening treatments can make your teeth up to 12 shades whiter almost immediately.
What Can I Expect From the KöR Teeth Whitening System?
Dr. Stein uses the advanced KöR whitening system in her office to give you the brightest, whitest smile possible without pain. The system uses a professional-strength whitening gel to brighten teeth quickly and efficiently, typically in under one hour. During treatment, Dr. Stein will apply the KöR whitening gel to your teeth for a period of time, which will depend on your desired level of whiteness. After your results have been achieved, there is no downtime necessary after your appointment.
Managing Sensitivity After Teeth Whitening
While tooth sensitivity is often a temporary and manageable side effect of traditional whitening, the KöR system uses a unique formulation designed to minimize post-treatment sensitivity as much as possible. Known for its deep-bleaching capabilities and ability to target even stubborn stains, KöR opens up microscopic pores in the enamel to lift discoloration from within. This process can occasionally make teeth more sensitive to hot, cold, or sweet stimuli for a short period following treatment. However, the sensitivity is typically mild and resolves within a few days.
That said, there are several effective ways to manage post-whitening sensitivity such as:
- Using desensitizing toothpastes and rinses to help calm nerve responses inside the teeth
- Avoiding extremely hot or cold foods and beverages during the first 24–48 hours
- Communicating your concerns to your dentist in order to adjust the amount/concentration of the formulation applied
- Following all post-treatment instructions carefully, including wearing whitening trays only as directed if part of a take-home system
- Staying well hydrated to support the natural remineralization process of enamel, which helps reduce sensitivity more quickly
If sensitivity persists longer than expected, Dr. Stein and our team can evaluate your whitening plan and recommend the appropriate changes. With proper care and guidance, most patients find that any temporary sensitivity is well worth the long-lasting brilliance that KöR® whitening provides.
Are There Any Teeth Whitening Side Effects?
Teeth whitening is a relatively gentle process when compared to other dental procedures. However, your teeth may feel sensitive for a few days after your appointment. Depending on your situation, Dr. Stein may recommend avoiding certain foods and drinks following your whitening session. To minimize your chances of experiencing tooth sensitivity, try using toothpaste designed for men and women with sensitive teeth one week prior to your appointment.
