1. Zoom! In-Office Whitening
The Zoom! In-office method for whitening teeth is very popular, reliable ,effective with clear results and can be done alone or along with nightly treatments at home.
Key Benefits
- Highly Effective: Can lighten teeth up to 8 shades in one session.
- Fast Results: See a dramatically brighter smile the same day.
- Long-Lasting: Results can last from 6 months to 2 years with proper care.
- Safe & Controlled: Performed by our dentists to minimize sensitivity and protect your gums.
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 depends on several individual factors, such as the type of staining, your desired shade of whiteness, and the whitening method chosen. Since an effective and safe whitening treatment is personalised to your starting tooth colour and goals, the total fee will vary from person to person.
How Much Does Whitening Cost in Hong Kong?
As every patient’s tooth composition and whitening goals are different, we cannot provide an exact price without an in-person consultation. The total cost depends on factors such as the number of sessions needed to achieve your desired result and whether you choose in-clinic power whitening or a take-home kit.
For reference, based on current market rates—such as the fee schedule from Prince Philip Dental Hospital—in-clinic bleaching generally ranges between HK$4,800 and HK$10,000 per session, while a custom-made bleaching guard for at-home use typically ranges from HK$2,800 to HK$6,000. This serves as an indicative guide to help you understand the typical pricing level for professional whitening in Hong Kong.
Factors That Affect the Cost
Type of Staining
Intrinsic (internal) stains may require a different approach and more sessions than extrinsic (surface) stains.
Whitening Method
Powerful, single-visit in-clinic whitening has a different cost structure than a more gradual take-home kit.
Desired Results & Sessions
The level of whitening achievable and the number of sessions required to reach your ideal shade will influence the overall investment.
Consultation & Treatment Planning
Book a consultation at Smith & Jain Dentists to receive a personalised teeth whitening plan. 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 you have a clear and confident path to a brighter smile.
*Note: A prior consultation is required to ensure your teeth and gums are healthy enough for whitening. We also accept Health Care Vouchers for the preliminary check-up and cleaning.

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.
