Opalescence Go Whitening vs. KOR Whitening: Which is Ideal?


Table of Contents

As dentists at The Practice, we understand the importance of achieving a bright smile. With numerous teeth whitening options, determining which treatment best suits your needs can be challenging. This guide will explore the differences between two popular whitening methods.


Opalescence Go Whitening

A convenient and effective take-home whitening treatment. These pre-filled, disposable trays are designed for easy application. The trays are pre-loaded with a professional-strength whitening gel containing hydrogen peroxide.

Opalescence Go Whitening suits individuals looking for a cost-effective and hassle-free solution. The treatment is suitable for mild to moderate tooth discoloration and can produce results in as little as a week. The trays are comfortable to wear and adapt to the shape of teeth for maximum coverage and effectiveness.


KOR Whitening

A comprehensive system that combines at-home and in-office treatments. Unlike traditional whitening methods, KOR Whitening utilizes a proprietary whitening gel and trays to deliver oxygen deep into the tooth enamel, removing even the most stubborn stains.

KOR Whitening is ideal for individuals with severe tooth discoloration or stubborn stains. The system is custom-tailored, with fabricated trays to fit teeth. While KOR Whitening may require a more significant investment of time and resources, the results are often dramatic and long-lasting.


Comparing Effectiveness

It’s essential to consider the severity of tooth discoloration and the desired outcome. Opalescence Go Whitening is an excellent option for individuals with mild to moderate staining,. However, KOR Whitening may provide a more comprehensive solution for those with more significant discoloration.



Opalescence Go Whitening is designed for at-home use. The pre-filled trays eliminate measuring and dispensing the gel.

In contrast, KOR Whitening requires multiple visits to the dentist for custom tray fittings and follow-ups. While this requires a greater time commitment, many patients find that the comprehensive nature of KOR Whitening leads to superior results.



Opalescence Go Whitening is more affordable, making it popular for budget-conscious individuals. Each treatment will run around $100. The pre-filled trays eliminate the need for custom fabrication, reducing material and labor costs associated with the treatment.

In contrast, KOR Whitening may require a bigger investment due to the custom-fitted trays and proprietary whitening gel. At the Practice, KoR is an in-office treatment that costs between $1000 and $1200.


Potential Side Effects

Some individuals may experience temporary tooth sensitivity or gum irritation. This subsides within a few days and can be managed with over-the-counter pain relievers or desensitizing toothpaste.

Seldom, overuse or misuse of teeth whitening products can lead to more severe side effects such as chemical burns or enamel damage. Follow the instructions and consult your dentist if you experience unusual or prolonged symptoms.

At The Practice, we prioritize patient comfort, and our team ensures teeth whitening treatments are administered safely and effectively. We will assess your oral health during the consultation and discuss potential risks or concerns.


Choosing the Appropriate Treatment

  • Severity of Discoloration: Opalescence Go Whitening may be suitable if you have mild to moderate tooth discoloration and are looking for a convenient, budget-friendly solution. However, KOR Whitening may offer more comprehensive results if you have severe discoloration or stubborn stains.
  • Convenience vs. Comprehensive Treatment: Opalescence Go Whitening is designed for convenience, with pre-filled trays worn at home. KOR Whitening may require multiple visits to your dentist. Consider your lifestyle and schedule when choosing between the two options.
  • Cost: While Opalescence Go Whitening is more affordable, it’s essential to consider each treatment’s long-term value and benefits. KOR Whitening may require a higher investment, but many patients agree the results and long-lasting effects justify the cost.
  • Preference: Some individuals may prefer the convenience and simplicity of Opalescence Go Whitening, while others may value the comprehensive results and customization KOR Whitening offers.
