Teeth Whitening
Teeth whitening is one of the most popular cosmetic dental treatments, but not all whitening is equal. If you are searching for professional teeth whitening in London, it is worth understanding the difference between clinical-grade systems and the unregulated kits widely available online, because the chemistry involved can either protect or permanently damage your enamel. At This Is It Dental, whitening is treated as a precise clinical procedure, carried out safely and monitored throughout.
Why Professional Whitening Matters: The Biology of Safety
Founded on Dr. Rena Uberoi's principle of exacting, highly personalised care, our approach focuses on achieving predictable, natural-looking results while strictly protecting the long-term biological health of your teeth. There is a significant clinical distinction between professional whitening and inexpensive online kits, one that comes down to safety, chemistry, and precision.
-
Protecting Your Gums from Chemical Burns
Generic trays do not fit the exact contours of your teeth. Whitening gels leak onto soft tissue, causing chemical burns, chronic irritation, and irreversible gum recession. Our custom trays are precision-milled from 3D digital scans with built-in microscopic reservoirs that hold gel securely against enamel while keeping it safely away from the gum margin.
-
Preventing Enamel Erosion
Many unregulated kits use acidic formulas to strip surface staining. While this temporarily brightens teeth, it causes permanent enamel thinning and increased porosity. We use advanced, pH-neutral bleaching systems incorporating remineralising agents, fortifying tooth structure while it whitens.
-
The Necessity of Pre-Treatment Screening
Whitening a tooth with an open micro-crack, hidden decay, or a leaking restoration allows bleaching agents direct access to the nerve, with potentially permanent consequences. Treatment at This Is It Dental always begins with a thorough dental assessment to confirm your mouth is biologically healthy enough for the procedure.
The Clinical Process
-
Clinical Assessment & 3D Scanning
We thoroughly examine teeth and gums to confirm suitability. A 3D digital intraoral scan creates the precise template for your custom whitening trays, no putty, no mess.
-
Canvas Preparation (Aquacare Airflow)
Before whitening begins, we recommend a hygiene session using Aquacare Airflow technology to lift away all plaque and extrinsic surface staining. This creates a perfectly clean enamel canvas, allowing the whitening gel to penetrate evenly and work at maximum efficacy.
-
Custom Tray Delivery & Education
Once your trays are fabricated, you return to ensure a flawless, snug fit. We provide your professional-grade gels and teach you exactly how to apply the precise amount of material to avoid any leakage.
-
Controlled Home Whitening
You wear your custom trays at night for a prescribed period (typically 14 consecutive nights). The low-concentration, slow-release gel gently breaks down deeply embedded colour molecules inside the dentine, lifting the baseline shade of your smile.
-
Final Evaluation & Shade Mapping
You return to the clinic so Dr. Uberoi's team can evaluate your final result, check your tooth health, and map your new shade against our clinical guides for future reference.

Frequently asked questions
Will professional whitening damage my enamel?
No. When administered by a dental professional using regulated, pH-neutral systems, teeth whitening is entirely safe. The materials temporarily open the microscopic pores of your enamel to release trapped colour molecules, but they do not strip or dissolve the mineral structure of your teeth. This is the fundamental distinction from many unregulated acidic kits.
I have naturally sensitive teeth. Can I still undergo whitening?
Yes. For patients with a history of sensitivity, Dr. Uberoi specifically recommends the Enlighten Evo system. Its refrigerated, pH-neutral formulation prevents the nerve irritation associated with acidic gels. We also provide specialised desensitising swabs to use throughout treatment, and many patients with pre-existing sensitivity complete the full course without any discomfort.
Will whitening change the colour of my crowns, veneers, or fillings?
No. Dental bleaching agents only react with natural human tooth structure, they have no effect on porcelain, composite resin, or acrylic. If you have visible restorations in your smile zone, we will sequence your care so that whitening is completed first. Once your natural teeth reach their optimal shade, any existing restorations that no longer match can be replaced.
How long will the results last?
Typically between one and three years, depending on lifestyle. Regular consumption of dark liquids, smoking, or inconsistent home hygiene will cause staining to return more quickly. Because you retain your custom-fitted trays, maintaining your result is straightforward, individual maintenance gel syringes are available from the clinic for periodic at-home top-ups.
Is there an age restriction?
Yes, professional tooth whitening is only appropriate for patients aged 18 and over. This is a UK regulatory requirement, not a guideline. Under-18s must not undergo bleaching treatment under any circumstances.
I have a single front tooth that has darkened after root canal treatment, can whitening fix it?
Standard external (extrinsic) whitening treats the whole arch evenly and will not lift a single tooth that has darkened from the inside following root canal treatment. For this, Dr. Uberoi offers internal (intracoronal) bleaching, where a whitening agent is placed inside the tooth itself, often alongside external whitening of the surrounding teeth, to bring the darkened tooth back in line with its neighbours.
