Teeth Whitening in Richmond, TX

Professional KoR Whitening by Dr. William Sung DMD

Teeth Whitening at Grand Mission

Coffee, tea, red wine, and years of daily life leave their mark on your enamel. Professional whitening removes those layers of discoloration and restores your teeth to a shade you feel genuinely good about. At Grand Mission, Dr. William Sung uses the KoR Whitening system, one of the most clinically advanced professional whitening systems available, because the results are deeper, longer-lasting, and more comfortable than what most systems deliver. Whether your staining is surface level or years deep, KoR has a protocol designed for your specific situation.

Are You a Candidate for Professional Teeth Whitening?

Most adults with stained or discolored teeth are good candidates for professional whitening. KoR is specifically appropriate for patients with sensitive teeth, patients who have had poor results with other whitening systems, and patients with deep intrinsic staining including tetracycline staining that other systems cannot treat.

Whitening is performed best when gums are healthy and any active decay or existing restorations have been evaluated. Dr. Sung reviews your specific situation at your consultation and recommends the right KoR protocol for your staining level and sensitivity.

Whitening will not change the color of existing crowns, veneers, or bonding. If you have visible restorations in the front of your mouth, this is discussed during your consultation so your expectations are accurate before you begin.

The KoR Whitening Process at Grand Mission

1

Consultation and Shade Assessment

Dr. Sung evaluates your teeth, identifies the type and severity of staining, and recommends the right KoR protocol for your specific situation. Your starting shade is recorded so your results can be measured accurately.

2

Custom Tray Fabrication

 Impressions of your teeth are taken and custom KoR trays are fabricated specifically for your mouth. The precision fit ensures the whitening gel maintains full contact with your enamel and prevents saliva dilution, which is the primary reason generic trays underperform.

3

At-Home Phase

You wear your custom trays with KoR whitening gel nightly for two to three weeks. The refrigerated gel is activated gradually over each session, breaking down deep-set stains without the spike of sensitivity that heat-activated systems cause.

4

In-Office Boost (KoR Max and above)

For the Max, Ultra, and Ultra-T protocols, an in-office session follows the at-home phase to deliver the deepest possible result. This combination of prolonged at-home treatment followed by in-office acceleration is what gives KoR its clinical edge over single-session systems.

4

Maintenance

A simple periodic at-home maintenance schedule keeps your results stable long-term. Most patients find one to two nights of touch-up every few months is all that is needed to maintain their whitened shade indefinitely.

How Long Does Teeth Whitening Last?

Whitening results vary by patient and by the type of staining treated. Here is what to realistically expect with professional KoR whitening.

With maintenance, KoR results are designed to last indefinitely. The at-home maintenance kit included with treatment allows patients to do periodic touch-ups that prevent color relapse from occurring the way it does with single-session systems.

Without maintenance, most patients see some degree of color relapse within six months to a year depending on dietary habits. Coffee, tea, red wine, and tobacco are the primary culprits.

Factors that affect longevity:

Dietary habits: High staining food and beverage consumption accelerates relapse

Oral hygiene: Regular professional cleanings protect results significantly

Tobacco use: Smoking is one of the fastest ways to reintroduce staining

Type of original staining: Intrinsic tetracycline staining, once treated with Ultra-T, is more stable than extrinsic surface staining

 why patients choose grand mission dentistry for Teeth Whitening

KoR Whitening System

The most clinically advanced professional whitening system available. Refrigerated gel, custom trays, and a multi-protocol approach that achieves results where other systems stop working.

Works on Sensitive Teeth

KoR was specifically designed to minimize sensitivity while maximizing whitening depth. Built-in desensitizing agents make it the preferred system for patients who have struggled with discomfort from other whitening methods.

Tetracycline Protocols

Most whitening systems cannot treat tetracycline staining or deep intrinsic discoloration. KoR Ultra-T is the only protocol specifically engineered for it. If other dentists have told you your staining cannot be whitened, ask Dr. Sung about KoR Ultra-T.

Frequently Asked Questions About professional teeth whitening

How long does professional teeth whitening last?

KoR whitening results are designed to last indefinitely with the maintenance protocol included in your treatment. Without maintenance, most patients see some relapse within six to twelve months depending on dietary habits. Consistent use of the maintenance kit keeps results stable long-term.

What is the difference between KoR whitening and Zoom?

KoR uses refrigerated gel and a combined at-home and in-office protocol that works on deep intrinsic staining including tetracycline. Zoom uses LED light activation in a single in-office session and is not effective on deep staining. KoR causes significantly less sensitivity. Zoom delivers faster single-visit results for mild to moderate surface staining. Grand Mission uses KoR.

Will whitening work on crowns, veneers, or bonding?

No. Whitening agents only affect natural tooth enamel. Existing crowns, veneers, and bonding will not change shade. If you have visible restorations, Dr. Sung discusses this at your consultation so your treatment plan accounts for it accurately.

Can whitening treat tetracycline staining?

Yes, with the KoR Ultra-T protocol. Tetracycline staining is one of the most challenging forms of dental discoloration. Most systems cannot treat it. KoR Ultra-T was specifically developed for this indication and has documented clinical success with cases that were previously considered untreatable.

How much does professional whitening cost in Texas?

KoR whitening protocols at Grand Mission range from $400 for the at-home kit to $1,800 for the Ultra-T tetracycline protocol. Most patients choose KoR Max at $600 to $900. Read more: Professional Teeth Whitening Is All Your Smile Needs Right Now
