KöR Whitening

Dr. Steven evaluates your teeth, documents your current shade, and determines which KöR protocol is appropriate for your case. KöR offers several levels of treatment — from standard whitening to KöR Ultra-T, which is specifically formulated for tetracycline staining. He'll review realistic outcome expectations based on the type and depth of your staining, and discuss any existing restorations that will not change color with whitening.

Precise impressions or a digital scan are taken to fabricate your custom KöR-Seal trays. These trays are engineered differently from standard whitening trays — they seal at the gumline to prevent saliva and sulcular fluid from mixing with the gel. Saliva contains enzymes that rapidly deactivate most whitening gels (within 25–35 minutes). The KöR-Seal design keeps the gel active for the full 6–8 hours of wear, which is what makes KöR fundamentally more effective.

Your KöR gel and trays are dispensed refrigerated — KöR gel is stored cold to preserve potency. You wear the trays nightly for 6–8 hours over approximately two weeks. This phase gradually opens dentinal tubules and conditions the teeth, making them more receptive to the deeper in-office treatment that follows. The gel must be kept refrigerated between uses.

The in-office phase uses a stronger KöR gel applied chairside. Because your teeth have been conditioned by the at-home phase, the in-office treatment drives whitening deeper than either phase could achieve alone. This appointment completes the active whitening process and is where the most dramatic shade changes occur.

Dr. Steven evaluates your final result and establishes a maintenance protocol. Unlike most whitening systems, KöR results are designed to be permanent with simple periodic maintenance — typically one night of at-home whitening per month using your trays. As long as the maintenance schedule is followed, the results do not regress.
