If you’ve tried strips, pens, and LED gadgets and your teeth still look yellow—or you’re dealing with gray or brown banding—over-the-counter whitening probably isn’t the problem. The chemistry is. Deep, intrinsic stains need a professional system strong enough to reach below the surface without wrecking your enamel. That’s where KöR Whitening shines. At Trident Smiles Dental in Sunnyvale, we use KöR for patients who want proven, long-lasting results when nothing else has worked.
Why Some Teeth Don’t Whiten With Strips
Whitening strips and drugstore trays rely on low-strength peroxide that only touches the outer layer briefly. They can lift light surface stains from coffee or tea, but intrinsic discoloration—age-related yellowing, antibiotic (tetracycline) banding, fluorosis, or long-standing stain molecules lodged deep in enamel—rarely budges.
KöR tackles this by restoring your enamel’s ability to absorb oxygen from the gel for extended periods, breaking down large stain molecules that conventional products can’t reach.
How KöR Whitening Works (And Why It’s Different)
- Refrigerated gels preserve potency from factory to your tray (peroxide breaks down at room temp).
- Custom-sealed trays keep saliva out and active gel against enamel for hours—critical for deep stain removal.
- Extended wear protocols (usually nighttime) increase oxygen diffusion into the tooth structure.
- In-office power sessions (when indicated) complement at-home phases for resistant cases.
The upshot: better chemistry, better contact time, better seal—so you get better results.
Who Is A Good Candidate?
- You’ve tried strips or standard whitening with little success
- You see gray or brown banding (possible tetracycline history)
- Your teeth look uniformly yellow despite good hygiene
- You have an event deadline and want predictable, noticeable change
- You’re planning veneers but want to whiten the baseline shade first
We begin with an exam to confirm your teeth and gums are healthy, rule out decay, and discuss any sensitivity history so we can personalize your plan.
What Your KöR Journey Looks Like
Consultation And Shade Baseline
Photos, shade mapping, and a candid conversation about goals. We’ll show you realistic before/afters so you know what to expect.
Precision Impressions For Custom Trays
Your trays are trimmed to seal at the gumline, keeping saliva out and gel in—a big reason KöR outperforms generic trays.
At-Home Whitening Phase
Most patients wear KöR gel overnight for 2–8 weeks, depending on starting shade and stain type. We’ll check progress and tweak the timeline as needed.
In-Office Session (If Indicated)
For certain deep stains, we add an in-office application to accelerate results. This is paired with sensitivity-reducing strategies to keep you comfortable.
Shade Lock-In And Maintenance
We’ll capture after photos, compare to your baseline, and give you a simple maintenance routine so your results last.
Sensitivity: What To Expect
Many patients report less sensitivity with KöR than past whitening experiences because of the sealed trays and tailored desensitizing protocol. If you’re prone to zingers, we’ll precondition your teeth and adjust wear time. Most people do fine with minor, temporary sensitivity that resolves within 24–48 hours.
Results And Longevity
KöR can brighten several shades—even with intrinsic staining—when OTC options fail. Longevity depends on habits: daily coffee, tea, or red wine will slowly re-introduce surface pigments. A few maintenance nights with your trays every 1–3 months (or before events) keeps your shade dialed in.
KöR Vs. Veneers: Which Should You Choose?
- KöR is ideal if your tooth shape is good and your main goal is a whiter shade.
- Porcelain veneers are better if you also need to correct shape, chips, spacing, or heavy wear.
- Many patients whiten first, then complete subtle bonding or a couple of veneers to perfect symmetry.

Safety And Enamel Health
Professional whitening is safe when supervised. We only proceed after ruling out cracks, active decay, or gum inflammation. Your hygienist will remove tartar and polish before treatment so gel reaches enamel evenly, and we’ll show you how to minimize acid exposure and protect enamel between sessions.
Frequently Asked Questions
How long does KöR whitening take?
Most cases run 2–4 weeks; deep tetracycline-type stains may need 6–8 weeks plus an in-office session. We’ll tailor the plan to your starting shade and goals.
Will KöR work if strips didn’t?
That’s exactly the point. The sealed trays, refrigerated gel, and longer wear time are designed to address stains that OTC methods can’t touch.
Is it safe for sensitive teeth?
Yes, with personalization. We use desensitizers, adjust wear time, and monitor progress. Most patients experience only mild, temporary sensitivity.
How white will my teeth get?
Everyone’s enamel is different, but KöR reliably lifts multiple shades. We’ll show you realistic case photos during your consult.
How do I maintain results?
Rinse after dark drinks, consider a straw, and do occasional maintenance nights with your custom trays. Keep up six-month cleanings.
