Teeth whitening continues to be one of the most requested cosmetic treatment requests that we receive in 2025. In fact, dental bleaching is projected to drive a global dental industry worth 10.6 billion by 2030 [1] (Rao and Saha). Many patients who reach out to our clinic often inquire about our whitening options, pricing, and the safest and most effective system that works for their smile. At Enamel Dentistry, we’ve simplified the process by offering various whitening solutions including Opalescence Go, Boost In-Office Whitening, and Kör Whitening. This guide breaks down each of our available options, what’s available on the market, and who each option is best suited for.
Opalescence Go is our entry-level whitening system. This was a patient-centered kit designed for a convenient, pre-filled takehome tray for patients who want flexible, budget-friendly whitening without a full custom kit. This 40% hydrogen peroxide formula is a chemically-activated whitener, ultimately not requiring LED lights. Opalescences continues potassium nitrate and fluoride. [2] (Opalescence)
Boost is our mid-tier, in-office whitening system that uses a chemically activated professional-strength peroxide gel. Unlike other at-home systems, this in-office treatment option does not require light or heat. Typically high-concentration in-office peroxide outperform take-home kits for immediate shade change.
Kör whitening is our most advanced whitening system and specifically designed for patients with deep stains, including those from antibiotic (tetracycline) induced discoloration, long-term pigment saturation, or fluorosis. By utilizing a proprietary tribarrel hydremide-peroxide gel formulation. The Kor-Whitening system is able to cleanse debris from between enamel prisms (interprismatic spaces) and within enamel prisms by sealing saliva out of the whitening tray. This ultimately rejuvenates the enamel itself [3] (Kor Whitening)
In fact, yes. All three systems work by releasing oxygen free radicals that break down large, colored organic molecules into smaller, less pigmented compounds through oxidation-reduction reactions. The peroxide penetrates through enamel rods into the dentin, where most tooth discoloration originates. While these dental whitening techniques promote color change, at-home and combined techniques may cause greater dental sensitivity than in-office techniques [4] (Pinto et al)
Whitening systems differ in strength, delivery, depth of whitening, and sensitivity risk, but all rely on peroxide releasing oxygen radicals to break down stain molecules. In-office systems produce the fastest, safest, and most dramatic results, while takehome kits lighten more slowly. KöR offers the deepest bleaching option, especially for difficult intrinsic stains.
Pricing reflects the concentration of whitening gel, level of customization, dentist supervision, tray design, and the whitening depth achieved (surface vs intrinsic)
Not always. Opalescence Go is perfect for mild stains. Boost is best for fast, event ready whitening. KöR is reserved for deep discoloration or patients wanting the most dramatic result.
No – peroxide does not remove enamel. Sensitivity is temporary and related to fluid shifts in dentin.
Many sensitive patients benefit from KöR’s low-sensitivity protocol or a gradual whitening approach with Opalescence Go. Pre-conditioning with potassium nitrate toothpaste also reduces sensitivity.
