Current Protocol for Successful Treatment of Difficult Whitening Cases

KöR Whitening offers effective noninvasive treatment for difficult stains

Andrew Green, DDS

Figure 1 | Stains from fluoride and tetracycline are extremely resistant to conventional whitening techniques. They are more inorganic than other sources of tooth discoloration, meaning that both types of stains are extremely difficult to convert. Both fluoride and the tetracycline family of antibiotics bind so strongly to the hydroxyapatite molecules that comprise enamel, dentin, and bones that they actually become part of the molecular structure.

These stains have previously been nearly impossible for dental professionals to whiten successfully. Typical whitening systems cannot sufficiently penetrate the microstructure of the teeth and consequently have not proven effective in converting these resistant inorganic stains.

KöR-Seal™ Whitening Trays are designed to seal out salivary and sulcular fluid contamination, which both contain high concentrations of antioxidant enzymes that destroy whitening gels on contact. The seal greatly extends the time that the whitening gel penetrates the microstructure of the teeth.

KöR is the first complete whitening system to be refrigerated from the moment of manufacture until it is received cold-packed by the dental practice. This offers several benefits:

  • Chemical stabilizers are not necessary and are not used, resulting in more instability and greater breakdown when placed in the mouth.
  • Chemical stabilizers cause sensitivity during whitening because they increase the osmolarity of the whitening gel by as much as 11 times, and therefore, there is 11 times more pull on dentinal tubular fluid. KöR gels have as little as 1/11 the osmolarity, resulting in significantly less sensitivity.
  • KöR products are always received at virtually the same effectiveness as the day of manufacture.

Additionally, the KöR in-office Hydremide® Peroxide is the first whitening gel in a Tri-Barrel™ delivery system. There are many chemicals that cannot be mixed together until ready for use. The Tri-Barrel delivery enables the addition of more ingredients, thereby resulting in a more sophisticated, highly effective formulation delivering exceptional results for all whitening cases.

Key Takeaways

  • Seals out fluids that compromise peroxide effectiveness
  • Refrigeration ensures virtually the same effectiveness as the day of manufacture
  • Tri-Barrel delivery system enables more ingredients and more effective whitening
