Frequently Asked Questions

Why Does Deep Bleaching Work so Well? 
KoR Deep Bleaching works by restoring your teeth’s ability to absorb oxygen. The oxygen from its bleaching gel is absorbed deeply into the tooth, dissolving stain molecules.

How Long Does KoR Deep Bleaching Last? 
Unlike other bleaching methods, with easy periodic home maintenance, KoR Deep Bleaching is entirely permanent.

Is it Safe? 
Bleaching products have been clinically studied and safely used on millions of patients without harm to teeth or gums. Bleaching is considered entirely safe.

Is There Pain or Discomfort with Deep Bleaching? 
Many have experienced pain during teeth whitening. Maybe you’ve experienced it yourself. After several years of research, development and clinical testing, the inventor of KoR Deep Bleaching introduced a bleaching gel that, in most cases, produces little to no sensitivity. As a result, most patients have no discomfort from bleaching when using this technique. Testing has shown that patients who do feel some sensitivity using KoR Deep Bleaching typically feel no more than 10% of the sensitivity they’d feel from other bleaching gels.

Does it Matter how Old I Am?
The ideal age to whiten teeth is about 14. The younger teeth are, the more brilliantly they whiten. However, KbR Deep Bleaching rejuvenates even older teeth back to their youthful ability to whiten incredibly well, even if you’re 90 years old.

How White will my Teeth Get? 
Deep Bleaching whitens teeth dramatically, often lightening them 16 shades or more. Although everyone is different, with the proper KbR Deep Bleaching technique, all teeth will have stunning results. It even whitens tetracycline-stained teeth!

Will my Teeth Look too White and Unnatural? 
No. Real teeth can’t look unnatural, they just look beautifully white. If you have seen people with ultra-white, fake-looking teeth, these were probably false teeth, teeth with porcelain crowns or veneers that may have been made too white and too opaque. You’ll get the ideal shade that’s right for you.

Will my Crowns, Veneers or Fillings Whiten Too? 
No. If you have any of these on your front teeth, you may need to replace some of them after bleaching.

How will Coffee, Tea, Smoking and Red Wine Affect my Teeth After Deep Bleaching? 
With your easy home maintenance, these staining foods will have no effect on the brilliant color of your teeth. No more spots or two-tone results

Will the Bleaching Trays be Uncomfortable, Difficult to Sleep with or will the Bleach Leak out of the Trays? 
No. KoR Deep Bleaching Trays ‘” are very different. They’re comfortable; because they’re thin and form-fitting, you’ll forget they’re even in your mouth. They’re convenient; by wearing these only while you sleep, it doesn’t interfere with your busy day. Also, unlike regular trays, KoR Deep Bleaching Trays seal the bleach inside the tray, preventing the gel from quickly leaking into your mouth.

How does the KoR Deep Bleaching System Work?
First, we’ll make molds of your teeth so you can have your own unique, ultra-comfortable KoR Deep Bleaching Trays to wear with our bleaching gel. Then you’ll have a simple visit in the dental office, followed by wearing KoR Deep Bleaching Trays for two weeks at home while you sleep. The KoR Deep Bleaching System is completed with a final visit in the dental office.

Is KoR Deep Bleaching More Expensive? 
Yes, it is. KoR Deep Bleaching involves more time and effort on the part of your dental team to ensure superior results. It is the most effective bleaching technique ever developed, based on years of extensive research. Along with very easy at-home maintenance, your investment in KoR Deep Bleaching will provide a beautiful smile for life, even if you drink red wine, tea and coffee.
