The Philosophy: Why "Home" Whitening is Superior
In the cosmetic industry, there is a misconception that "faster is better." You may see clinics advertising "1-hour laser whitening." At the Cosmetic Dentistry Clinic, we consciously choose not to offer laser activation.
Why? Because Slow Luxury yields better results.
Scientific studies consistently show that "power whitening" (using UV lights) often dehydrates the tooth, creating a temporary "chalky" whiteness that fades quickly as the tooth rehydrates. It also carries a higher risk of acute sensitivity ("zings").
We believe in Deep Bleaching. By using custom-fitted trays at home over a period of 10–14 nights, the active oxygen has time to penetrate deep into the dentine tubules. This breaks down stubborn intrinsic stains (like coffee, wine, and tetracycline) gently and permanently. The result is a stable, lustrous white that glows, rather than a flat, dehydrated white that fades.
The Technology: No More "Goo"
If you have had whitening trays made in the past, you likely remember the discomfort of alginate impressions—the metal tray filled with cold, suffocating putty that makes you gag.
Welcome to the Digital Age.
We have eliminated physical impressions entirely. We utilise state-of-the-art Intraoral Scanners.
- The Scan: A slim camera wand glides over your teeth, capturing 6,000 images per second.
- The Comfort: You can breathe, swallow, and pause at any time. There is no mess and no taste.
- The Precision: Digital scans are accurate to the micron. This is critical for whitening.
Why Precision Matters
The success of home whitening depends entirely on the Seal. If oxygen leaks out, it doesn't work. If saliva leaks in, it dilutes the gel.
Our digitally manufactured laboratory trays fit your teeth like a second skin. This "vacuum seal" ensures the gel stays exactly where it needs to be—on your enamel—and away from your gums, preventing irritation.
The Chemistry: How Oxygen Cleans
To understand the value of this treatment, one must understand the chemistry. Teeth are porous, like a sponge. Over years, microscopic pigments from red wine, espresso, berries, and spices become trapped deep inside the crystal structure of the enamel. Brushing only cleans the surface.
Our system uses Carbamide Peroxide.
Application: You place a small droplet of gel into your custom tray.
Activation: As the gel warms to body temperature, it breaks down into water and oxygen.
Permeation: The oxygen molecules penetrate the enamel surface and enter the dentine.
Oxidation: These molecules attack the carbon bonds of the discoloured pigments, shattering them into colourless particles.
The structure of the tooth remains unchanged; only the colour reflects light differently. It is safe, non-abrasive, and biologically sound.
The Process: Your Journey to Brilliance
We have refined the whitening process into two simple visits.
Visit 1: The Digital Scan (20 Minutes)
- • We perform a shade assessment, using a natural light guide to determine your current baseline colour.
- • We check your dental health to ensure you have no open cavities or leaking fillings (whitening requires a sealed environment).
- • We perform the 3D Digital Scan of your upper and lower teeth.
- • The data is sent instantly to our dedicated laboratory.
Visit 2: The Fitting (15 Minutes)
- • You return to collect your bespoke trays and your whitening kit.
- • We check the fit to ensure the seal is perfect.
- • We demonstrate exactly how to apply the gel—showing you how "less is more" to avoid gum irritation.
- • We provide you with desensitising protocols if you have sensitive teeth.
The Home Phase (14 Nights)
- • You wear the trays while you sleep (or for 2–4 hours in the evening if preferred).
- • You will likely notice a difference after the 3rd night.
- • By the 14th night, you will have reached your maximum brightness.
The "White Diet": Protecting Your Investment
During the 2-week active whitening phase, the "pores" of your teeth are open. This makes them susceptible to restaining. We advise patients to follow the "White Diet" for optimal results.
The Rule: If it would stain a white shirt, it will stain your teeth.
Avoid:
Red wine, black coffee, tea, turmeric/curry, soy sauce, tomato sauce, blueberries, beetroot.
Embrace:
White wine, clear spirits, chicken, fish, rice, pasta (white sauce), cauliflower, potatoes, bananas.
Note: You only need to follow this strict diet during the 14 days of treatment. Once the process is complete, the pores close, and you can resume your normal diet.
The Investment: Limited Time Offer
Professional whitening is the single most impactful "entry-level" cosmetic treatment available. It instantly rejuvenates the face.
While our standard fee reflects the high cost of digital scanning and laboratory fabrication, we are currently running a Limited Time Promotion to welcome new patients to the clinic.

Synergistic Treatments: The "Mini Makeover"
Whitening is rarely the end; it is the beginning. Once your teeth are their ideal shade, many patients choose to refine the shape.
The "Align, Bleach & Bond" Protocol
This is our signature non-invasive makeover.
- Align: Use ProAligners to straighten the teeth.
- Bleach: Use this Whitening System to brighten them.
- Bond: Use Composite Bonding to fix chips or jagged edges.
Important: Composite bonding and porcelain veneers do not whiten. Therefore, you must complete your whitening treatment before having any bonding or veneers placed, so we can match the new restorations to your new, brighter shade.
Why South Kensington Chooses Us
1. The "Zero-Sensitivity" Protocol
Sensitivity is the main barrier to whitening. We use gels that contain Potassium Nitrate and Fluoride, which calm the nerve during the process. Our digital trays also prevent the gel from leaking onto the gums, which is the primary cause of pain.
2. The Digital Fit
Old-fashioned putty moulds can distort, leading to loose trays. Loose trays mean uneven whitening. Our digital scans are accurate to the width of a human hair, ensuring the gel is held firmly against the tooth for consistent results.
3. The Ongoing Relationship
Unlike buying a kit online, you are under the care of a dentist. If you experience sensitivity, we adjust the concentration. If you want to go brighter, we can supply "top-up" syringes at your routine check-ups for a nominal fee, allowing you to maintain the result forever using your original trays.
Frequently Asked Questions (FAQ)
Will it look fake?
No. Natural teeth have a limit to how white they can go (the "saturation point"). Home whitening restores your teeth to their natural genetic maximum brightness. It will look like you have incredibly healthy, clean teeth, not "Tippex" white.
How long does it last?
Permanence is relative. The result is permanent, but your lifestyle will continue to stain your teeth over time. Most patients find their smile remains stable for 12–24 months. We recommend a "top-up" (wearing the trays for 1–2 nights) once every 6 months to maintain the peak brightness.
Is it safe for my enamel?
Yes. Extensive research confirms that carbamide peroxide, when used in a custom tray, does not damage or thin the enamel. It is one of the safest procedures in dentistry.
Does it work on crowns or veneers?
No. Whitening gel only affects natural tooth structure. It will not change the colour of existing porcelain crowns, veneers, or white fillings. If you have these on your front teeth, you may need to have them replaced after whitening to match the new shade.
Why is this better than "strip" whitening bought in shops?
Over-the-counter strips are generic shapes. They do not fit into the grooves of your teeth, leading to "stripes" of yellow where the strip didn't touch. They also contain very low concentrations of peroxide (by law). Our system is prescription-strength and custom-moulded for full coverage.
Illuminate Your Confidence
There is no better accessory than a radiant smile. It is the first thing people notice and the last thing they remember.
With our current offer, there has never been a better time to invest in your luminosity.
