Teeth Whitening in Sunnyvale, CA

Professional Whitening Options for a Brighter, More Confident Smile

Stained or discolored teeth can make even the healthiest smile appear aged or neglected. At Harmony Smile Dental, we offer two advanced professional teeth whitening treatments—KöR Whitening and Zoom Whitening—to dramatically brighten your smile with safe, clinically proven methods.

Led by Dr. Ryan Zhao, our team will help you determine the right solution to lift stubborn stains and restore your teeth’s natural brilliance—all while protecting your enamel and oral health.

Is Teeth Whitening Right for You?

Over time, common foods and beverages—such as coffee, tea, wine, and berries—can leave behind stains. Additionally, aging, medications, and tobacco use may cause internal or deep-set discoloration that over-the-counter whitening products can’t address.

Professional teeth whitening is ideal for patients who:

• Have yellow or brown surface stains
• Want faster and more reliable results than drugstore kits
• Need a personalized approach for sensitive teeth or previous dental work
• Prefer clinically supervised, long-lasting results

During your consultation, we’ll also evaluate your oral health to ensure you’re a good candidate for whitening. If any decay or gum issues are present, we may recommend addressing them first through general dentistry such as dental cleanings and exams or fillings.

Our Whitening Options

KöR Teeth Whitening

KöR is one of the most advanced whitening systems available and is particularly effective for deep intrinsic stains—such as those caused by tetracycline. It uses a series of high-potency gels combined with custom-sealed trays and refrigeration technology to maximize stain removal.

• Ideal for resistant or aging stains
• Minimal sensitivity
• Both in-office and take-home treatment options

Zoom Teeth Whitening

Zoom is a fast, light-activated system that can whiten teeth up to 8 shades in a single appointment. Great for special events, Zoom is best for patients who want immediate results with a short treatment time.

• Completed in about 45–60 minutes
• Great for mild to moderate stains
• Custom trays available for at-home maintenance

Not sure which treatment is right for you? Dr. Zhao will walk you through the pros and cons of each during your cosmetic consultation.

Why Choose Professional Whitening Over Store-Bought Products?

While many whitening strips and gels promise results, only professional treatments offer the strength and precision needed to achieve noticeable, uniform whitening—safely and efficiently. Benefits of our in-office systems include:

• Stronger, faster-acting formulas
• Reduced risk of gum or enamel irritation
• Results tailored to your smile shade and sensitivity
• Long-term guidance and follow-up care

Many of our whitening patients choose to combine their treatment with other cosmetic services like clear aligners, veneers, or dental bonding for a complete smile makeover.
