KöR Teeth Whitening
Professional Whitening, Personalized to Your Smile
Refresh your smile with the KöR professional whitening system and a treatment plan designed around your teeth, sensitivity, and desired result.
At Mandarin Dentistry, whitening begins with a comprehensive evaluation—not a one-size-fits-all product.
A More Considered Approach to a Brighter Smile
Tooth color can change gradually because of age, diet, lifestyle, medications, and the natural character of the enamel and dentin.
Store-bought products are generally designed for broad use and may not address every type of discoloration. Professional whitening allows your dentist to evaluate why your teeth appear darker and recommend a protocol suited to your smile.
Mandarin Dentistry offers KöR, a professionally supervised whitening system that uses specially formulated whitening gel and precisely fitted trays.
Depending on your starting shade and goals, your treatment may involve an at-home protocol, in-office care, or a combination of both.
Why Patients Choose KöR
Professional Care From Beginning to End
KöR whitening is designed to offer a more personalized experience than an over-the-counter product.
Potential benefits include:
- A protocol selected for your type of discoloration
- Custom-fitted whitening trays
- Professionally dispensed whitening gel
- Guidance on application and wear
- Strategies for managing sensitivity
- Progress monitored by a dental team
- Options for maintaining your result
- Coordination with other cosmetic treatment
Your outcome will depend on your natural tooth color, the cause and depth of the staining, your consistency with the protocol, and how your teeth respond.
No whitening system can guarantee one particular shade for every patient.
What Causes Tooth Discoloration?
Understanding the Color of Your Smile
Identifying the likely cause helps us recommend the appropriate treatment and set realistic expectations.
Teeth can become discolored for several reasons.

Natural Aging
The outer enamel can become thinner with time, allowing the naturally warmer color beneath it to become more visible.

Surface Staining
Coffee, tea, red wine, tobacco, and certain foods can gradually leave stains on the enamel.

Dental Trauma
An injury may cause one tooth to become darker than the surrounding teeth.
Your Whitening Consultation
A Brighter Smile Begins With a Healthy Foundation
Before beginning whitening, we will evaluate your teeth, gums, existing restorations, and any history of sensitivity.
The consultation helps ensure that whitening is both appropriate for your smile and coordinated with your long-term dental care.
Your consultation may include:
01
A conversation about your goals
We will discuss your starting shade, the result you would like, and any previous whitening experiences.
02
An oral-health evaluation
Cavities, gum inflammation, exposed roots, cracks, or other concerns may need to be addressed before whitening begins.
03
A review of existing restorations
Crowns, veneers, bonding, and fillings will not lighten with whitening gel.
04
An assessment of sensitivity
Your history helps us plan a more comfortable treatment experience.
05
A personalized recommendation
We will explain the appropriate KöR protocol, expected timeline, limitations, and maintenance plan.
Custom Whitening Trays
Designed for a Precise, Comfortable Fit
Your KöR trays are created from detailed impressions or a digital scan of your teeth.
A precise fit helps hold the whitening gel in the intended position while limiting unnecessary contact with the surrounding gum tissue.
At your delivery appointment, our team will:
- Confirm the fit of your trays
- Show you how much gel to use
- Explain how to insert and remove them
- Review the recommended wear schedule
- Demonstrate how to clean and store the trays
- Discuss what to do if sensitivity occurs
- Answer questions before you begin
Using the trays and gel exactly as directed is important for both comfort and results.
Your specific KöR protocol will depend on the condition and starting color of your teeth.
Treatment may include:
Your Whitening Experience
What to Expect
Custom-fitted take-home trays
In-office treatment when appropriate
Professionally dispensed KöR whitening gel
Progress evaluations
A personalized maintenance plan
A prescribed schedule for wearing the trays
Whitening occurs gradually. You may notice changes during treatment, but the final result can continue to develop according to the protocol.
Your doctor will explain the anticipated timeline and help you understand what can reasonably be achieved.
Managing Sensitivity
Comfort Is Part of the Plan
Temporary tooth sensitivity and gum irritation can occur with any peroxide-based whitening treatment.
Before you begin, we will ask about your sensitivity history and explain how to use the system correctly. Depending on your needs, we may recommend adjustments to the amount of gel, wear schedule, or supporting products.
Contact our office if you experience:
- Significant or persistent sensitivity
- Gum irritation that does not improve
- Sharp pain in a specific tooth
- Changes that concern you
- Difficulty wearing the trays comfortably
Whitening should not be continued through severe or unexplained pain without speaking with your dentist.

Whitening and Existing Dental Work
Natural Teeth and Restorations Respond Differently
Whitening gel changes the color of natural tooth structure. It does not lighten:
Porcelain veneers
Dental crowns
Tooth-colored fillings
Cosmetic bonding
Dental bridges
Implant restorations
If these restorations are visible when you smile, whitening may create a difference between their shade and the surrounding teeth.
This does not always prevent you from whitening. It simply means the sequence should be planned carefully.
In some cases, we may recommend whitening first and then replacing selected restorations so they complement the new shade.

KöR may be appropriate for adults who want to address generalized tooth discoloration and have healthy teeth and gums.
Whitening may need to be delayed, modified, or replaced by another treatment if you have:
Who Is a Candidate?
Whitening Is Not Right for Every Smile
Untreated cavities
Significant tooth sensitivity
Exposed tooth roots
Active gum disease
Extensive visible restorations
Cracked or compromised teeth
Whitening also may not produce the same result on every tooth.
Your consultation allows us to determine whether KöR is the right option or whether another cosmetic treatment would better address your concern.
Maintaining Your Result
Keeping Your Smile Looking Its Best
Whitening results are not permanent. Teeth can gradually develop new stains over time.
You can help maintain your smile by:
- Following the KöR maintenance protocol provided by your doctor
- Brushing twice a day
- Cleaning between your teeth daily
- Attending professional cleanings
- Rinsing or brushing after stain-producing foods and drinks
- Limiting tobacco use
- Storing your trays as instructed
- Contacting us before ordering replacement gel
Your maintenance needs will depend on your habits, natural tooth color, and desired brightness.
Professional Whitening vs. Store-Bought Products
The Value of a Personalized Plan
Over-the-counter products may improve some surface staining, but they are not designed around your specific oral health, restorations, sensitivity, or type of discoloration.
Whitening is elective, but it is still dental treatment. Professional oversight helps ensure that the health of your smile remains part of the process.
Professional whitening includes:
An evaluation before treatment
A diagnosis of possible causes of discoloration
A system selected for your needs
Custom-fitted trays when appropriate
Professional-strength materials
Guidance on safe application
Treatment Investment
Clear Information Before You Begin
The cost of KöR whitening depends on the protocol recommended for your smile.
Following your consultation, we will provide:
- The recommended treatment approach
- An estimated timeline
- Clear financial information
- Instructions for maintenance
- Information about available payment options
Cosmetic whitening is generally not covered by dental insurance.
