KöR Teeth Whiteningin Tustin, CA
Professional KöR Deep Bleaching in Tustin, CA, planned and supervised personally by Dr. Marta Rudat, DDS.
Results vary from person to person.
Quick answer
KöR Whitening is a professional Deep Bleaching system that combines a custom take-home tray phase with an in-office visit to lift stains other treatments leave behind. The gels stay refrigerated from the factory to your appointment, so they reach your teeth at full strength. The custom trays seal out saliva, which lets the gel keep working for hours instead of the few minutes a strip lasts.

Why see Marta Rudat, DDS, for teeth whitening in Tustin, CA?
Plenty of places will sell you a whitening kit. Far fewer will tell you whether whitening is even the right tool for the result you want.
Dr. Marta Rudat has practiced in Tustin for more than 15 years, earned over 495 five-star reviews, and belongs to the American Academy of Cosmetic Dentistry, where she is currently completing the Accreditation process, a multi-year review of documented patient cases that fewer than 500 dentists worldwide have finished.
What that means for your whitening: she looks at your enamel, your existing dental work, and the kind of staining you have before recommending anything. Whitening is one of the cosmetic services she offers.
KöR is genuinely effective, and it is also not the answer for every discoloration. Dr. Marta will tell you which one is for you.
The difference
What makes KöR different from
strips and one-hour lights?
Freshness
The first is freshness. KöR gels stay refrigerated from the moment they are made until they reach your teeth, so the peroxide arrives at full strength rather than half-degraded on a warehouse shelf.
The seal
The second is the seal. Saliva naturally breaks down whitening gel within about half an hour, which is why drugstore strips fade fast. KöR's custom trays are fitted to keep saliva out, so the gel can keep working for hours at a time while you sleep.
That combination is why KöR has a documented record against stains most systems struggle with, including deep tetracycline discoloration that resists everything else.
Results vary from person to person, and Dr. Marta sets expectations for your specific staining at the consultation.
Candidacy
Is KöR whitening right for you?
A good fit for KöR
Healthy teeth and gums with discoloration from age, coffee, tea, red wine, or tobacco
Anyone who tried strips or over-the-counter kits and wasn't satisfied
Stubborn or tetracycline staining, the exact problem the system was built to handle
When something else may serve you better
Whitening only lightens natural teeth, so it won't change existing crowns, veneers, or bonding
Already have dental work up front? Dr. Marta may whiten the natural teeth first, then match any restorations to the new shade
If the real concern is shape, chips, or gaps rather than color, a smile makeover plan gets you further
Planning veneers anyway? Whiten first, since veneers are color-matched to the teeth around them
The process
What happens during KöR whitening?
KöR is a planned process rather than a single zap, which is why the results last. Here is how a typical teeth-whitening case unfolds here in Tustin with Dr. Marta.
The consultation and shade check
You and Dr. Marta talk about the brightness you want and the staining you have. She examines your teeth and gums, records your starting shade, and confirms whitening is the right approach before anything begins.
Custom trays made for your teeth
Impressions or a digital scan are used to build trays fitted precisely to your teeth. The fit is what lets KöR outperform generic kits, because a tray that seals keeps the gel active for hours instead of minutes.
The at-home phase
You wear the take-home trays with professional-strength gel, usually overnight, for a set stretch of days. Most patients find this comfortable, and any sensitivity is managed as part of the plan rather than left for you to figure out.
The in-office visit (when indicated)
For deeper staining, Dr. Marta adds an in-office session with a stronger gel to accelerate and deepen the result. Not every case needs it, and she will tell you upfront whether yours does.
Maintenance that protects the result
A short, occasional touch-up at home keeps your shade bright over time. Whitening that holds comes from this maintenance step, and Dr. Marta walks you through exactly how little it takes.
Investment
What does KöR whitening
cost in Orange County?
Take-home tray phase
$500 – $700
Custom trays with professional-strength gel, worn at home.
Full Deep Bleaching protocol
$1,000 – $1,500
Combined in-office and at-home treatment.
In the Tustin and Orange County area, KöR whitening generally runs about $500 to $700 for the take-home tray phase on its own, and roughly $1,000 to $1,500 for the full Deep Bleaching protocol that combines in-office and at-home treatment.
Where your case lands depends on how deep your staining runs and whether any existing dental work needs matching afterward.
It helps to weigh that against the alternative many patients are already paying for: a steady stream of drugstore strips and kits that fade within weeks and never reach the deeper stains.
A professionally planned KöR result, kept up with the occasional touch-up, tends to be both brighter and longer-lasting. At your consultation in our Tustin practice, you get a clear estimate for your specific plan before you commit to anything.
Longevity
How long does KöR whitening last,
and how do I keep it?
With simple upkeep, KöR results can hold for years rather than weeks. The maintenance is light:
- an occasional night in your trays with a small amount of gel
- the everyday habits that protect any smile
- brushing twice a day, flossing
- keeping your regular cleanings
Coffee, tea, red wine, and tobacco are the usual culprits behind re-staining, and you do not have to give them up to stay bright. A rinse with water after and the occasional touch-up generally does the job.
Because you keep your custom trays, refreshing your shade later costs far less than starting over. Dr. Marta sends you home knowing precisely how to protect the result you paid for.

Frequently asked
KöR whitening questions,
answered.
The fee depends on whether your plan uses the take-home phase alone or the combined in-office and home protocol, how deep your staining is, and whether existing dental work needs matching afterward. Dr. Marta gives you a clear estimate at your consultation, so you know what your plan involves before deciding anything.
Yes, it has a documented record against difficult discoloration, including tetracycline staining that resists most other systems. The combination of refrigerated, full-strength gel and trays that seal out saliva is what lets it reach stains strips cannot. Results still vary by person, so Dr. Marta sets honest expectations for your case.
Some patients notice temporary sensitivity during whitening, and KöR is designed to minimize it. Dr. Marta builds sensitivity management into your plan and adjusts the protocol if needed, which is one advantage of whitening under a dentist rather than with a drugstore kit.
With occasional at-home touch-ups using the trays you keep, KöR results can hold for years. Everyday staining from coffee, tea, and wine is normal, and a short refresh now and then keeps your shade bright without starting over.
No. Whitening only lightens natural tooth structure, so crowns, veneers, and bonding keep their original shade. If you have visible dental work, Dr. Marta often recommends whitening your natural teeth first, then matching any restorations to the brighter shade.
Usually yes. Veneers are color-matched to the teeth around them, so whitening first gives you more control over the final brightness of your whole smile. Dr. Marta maps out the right sequence at your consultation if veneers are part of the picture.
Drugstore strips can lighten surface stains a little, but they fade quickly because saliva breaks the gel down within about half an hour, and they do little for deeper discoloration. KöR's custom trays and refrigerated gels are built to work longer and reach further, under a dentist's supervision.
