The Procedure: What to Expect

Step 1: Preparatory Cleaning

When you come in for Zoom teeth whitening your appointment will likely start with a normal teeth cleaning to make sure your teeth are clear of all the calculus and stains.

Step 2: Gel Application and Light Activation

  • After your cleaning, the dentist will treat your teeth with a hydrogen peroxide whitening gel.

  • They will then apply a bright UV light.

  • The bleaching gel reacts to the UV light, intensifying the whitening effect, which is why the in-office procedure is so effective as a one-time treatment.

  • You will need to hold the light device between your teeth during this time.

Step 3: Repeated Treatment Cycles

  • After 15 minutes, your dentist will re-apply the gel.

  • They will re-apply the gel again after another 15 minutes.

  • This creates a total of 45 minutes of whitening treatment (three 15-minute cycles).

Step 4: Post-Treatment Sensitivity Management

Immediately after your treatment, your teeth will be treated with a sensitivity-reducing fluoride past-gel to manage the tooth sensitivity that is a common response to teeth whitening.

*Note: This treatment is not suitable for everyone. Crowns, veneers, and composite fillings will not whiten and may need to be replaced after your natural teeth are lightened. We will advise you during your consultation.

2. BlancOne® Whitening

BlancOne® is an innovative professional teeth whitening system from Italy that has redefined the dental aesthetic experience. Unlike traditional whitening methods that often require long sessions and high concentrations of hydrogen peroxide, BlancOne® uses a unique photochemical technology.

Key Benefits

  • Ultra-Fast Results: Depending on the version (Click or Touch), the treatment can be completed in as little as 20 to 30 minutes. It is often performed immediately following a professional scaling and polishing session.
  • Minimal to No Sensitivity: Because it uses a lower concentration of whitening agents and a physiological pH, it significantly reduces the risk of post-treatment sensitivity or “zings,” which are common with traditional bleaching.
  • Enamel-Safe Technology: The photochemical reaction breaks down stains without the use of excessive heat or harsh chemicals, ensuring your tooth structure and enamel remain healthy and protected.
  • No “White Diet” Required: One of the most popular features for our patients is that BlancOne® does not dehydrate the enamel like other systems. This means you generally do not have to avoid coffee, tea, or red wine immediately after the treatment.
  • Versatile Options: From a quick “refresh” (BlancOne® CLICK) to a deep whitening (BlancOne® TOUCH), we can tailor the intensity to your specific needs.

The Procedure: What to Expect

Step 1: Preparation & Cleaning

To achieve the best results, we recommend a professional cleaning (scaling and polishing) first to remove surface plaque and tartar.

Step 2: Shade Selection

Our dental professional will measure your current tooth shade using a guide to track your progress.

Step 3: Gel Application

A specially formulated BlancOne® whitening gel is applied directly to your teeth. No uncomfortable gum barriers are typically required for the fast-acting versions.

Step 4: Light Activation

We use the specialized BlancOne® Arcus Light to activate the gel. The light triggers the photochemical reaction, accelerating the release of singlet oxygen to break down stains rapidly.

Step 5: Rinse & Reveal

After a few cycles of light activation (usually 4 to 10 minutes per cycle), the gel is rinsed away.

Step 6: Final Assessment

We compare the new shade to the initial measurement. You can walk out of our Central clinic immediately with a visibly brighter, refreshed smile.

3. At-Home Whitening Kits

Our Custom At-Home Whitening Kits offer a professional-grade alternative to generic over-the-counter products. By combining medical-grade whitening gels with trays molded precisely to your teeth, we ensure a safe, effective, and gradual transformation in the comfort of your own home.

Key Benefits

  • Custom-Fitted Safety: Bespoke trays ensure the gel stays on your teeth and off your gums, preventing irritation.
  • Professional Strength: Significantly more effective at removing deep stains than store-bought strips or kits.
  • Total Flexibility: Whiten whenever it suits you—whether for 30 minutes a day or overnight.
  • Controlled Comfort: The gradual process is ideal for sensitive teeth; you can easily adjust the frequency to suit your comfort level.
  • Reusable Value: Your custom trays can last for years—simply purchase gel refills from our Central clinic for future touch-ups.

The Procedure: What to Expect

Step 1: Consultation & Impressions

Our dental team examines your oral health and takes a digital scan or physical impression of your upper and lower teeth. This ensures your custom trays will fit perfectly.

Step 2: Lab Fabrication

Our laboratory technicians craft your bespoke whitening trays from high-quality, durable, and comfortable clear BPA-free material.

Step 3: Fitting & Instructions

Usually within a few days, you return to collect your trays and whitening kit. We will demonstrate how to apply the gel correctly and provide a personalized schedule based on your goals.

Step 4: The Home Phase Application

You apply a small tear-drop amount of gel into each tooth compartment of the tray.

  • Duration: Wear the trays for the prescribed amount of time (usually 1–4 hours per day or overnight).
  • Cleanup: Remove the trays, rinse your mouth, and clean the trays with a soft brush and cool water.

Step 5: Achieving the Goal

Most patients reach their desired shade within 7 to 14 days of consistent use.

Teeth Whitening Cost

The cost of professional teeth whitening in Hong Kong is influenced by several individual factors, including the type of staining, your desired shade of whiteness, and the whitening method chosen. Because a safe and effective whitening treatment must be personalized to your starting tooth color and aesthetic goals, the total fee will vary from person to person.

Factors Affecting the Cost

Type of Staining Intrinsic stains

(discoloration inside the tooth) may require a different clinical approach and more sessions compared to extrinsic stains (surface stains from food or lifestyle habits).

Whitening Method

The cost structure differs between powerful, single-visit In-Clinic Power Whitening and the more gradual, self-administered Take-Home Professional Whitening Kits.

Desired Results & Number of Sessions

The level of brightness you wish to achieve and the number of sessions required to reach that ideal shade will influence the overall investment.

Consultation & Treatment Planning

We invite you to book a consultation with our dental team for a personalized whitening assessment. During your visit, our dentists will conduct a thorough examination of your tooth shade and enamel condition, discuss your aesthetic goals, and provide a detailed cost estimate for the most suitable whitening option for you—ensuring a safe and confident path to a brighter smile.

*Important Note: A clinical consultation is mandatory before starting any whitening treatment to ensure your teeth and gums are healthy enough for the procedure.

Frequently Asked Questions About Teeth Whitening

Does professional teeth whitening damage my tooth enamel?

No. When performed by a dental professional, whitening is a safe chemical process that breaks down stains within the tooth. It does not “thin” or “scrape” your enamel. We use pH-balanced gels and protective barriers to ensure your tooth structure remains healthy throughout the procedure.

Why should I choose a dentist instead of a beauty salon for whitening?

In Hong Kong, only registered dental professionals are legally allowed to use high-concentration whitening agents (above 6% hydrogen peroxide). Beauty salons use much weaker, unregulated products or potentially dangerous high-heat lamps. A dentist also ensures you don’t have hidden cavities or gum disease, which could lead to extreme pain if whitening gel enters a decayed area.

I have very sensitive teeth. Can I still whiten them?

Yes! We specifically offer BlancOne® Whitening for patients with sensitivity. It uses a lower concentration of peroxide and a photochemical reaction that doesn’t rely on heat, making it much more comfortable. We also provide professional desensitizing treatments before and after your session to manage any “zings.”

Will whitening work on my existing crowns, veneers, or fillings?

Whitening agents only work on natural tooth structure. They will not change the color of porcelain, composite resin, or ceramic. If you are planning to replace old crowns or veneers, we recommend whitening your natural teeth first so we can match the new restorations to your brighter shade.

How long will the appointment take?

BlancOne® Click: ~20-30 minutes (often done right after your scaling/cleaning).

Zoom! In-Office: ~60 to 90 minutes for a full transformation.

Custom Kits: A 15-minute appointment for impressions, and a 10-minute follow-up to collect your trays.

What is the "White Diet" and do I need to follow it?

After a Zoom! treatment, your teeth are temporarily more porous. We recommend a “White Diet” (avoiding coffee, tea, red wine, soy sauce, and curry) for 48 hours. However, with BlancOne®, the enamel is not dehydrated to the same extent, so dietary restrictions are generally not required.

How often should I "touch up" my whitening?

To maintain a brilliant white, most patients perform a “touch-up” every 6 to 12 months. If you have our Custom Home Trays, you can simply buy a gel refill from our Central clinic whenever you feel your smile needs a refresh.
