KöR Whitening
The most powerful whitening system available — proven to whiten even the toughest stains.
The strongest whitening system in dentistry
KöR Whitening is widely regarded as the most effective professional whitening system available. It uses a unique tray seal that keeps the whitening gel active for hours, and it's the only system proven to whiten tetracycline-stained teeth — stains that are notoriously resistant to other treatments.
If you've tried other whitening methods without the results you wanted, KöR may be the answer. Call (708) 345-3440 for a consultation.
Is professional whitening right for you?
- Coffee, tea, wine, or smoking have left teeth dull or yellow.
- Store-bought strips haven't given you the result you wanted.
- You have a wedding, reunion, or photo session coming up.
- You want even, predictable results without gum irritation.
