Professional teeth whitening is one of the most popular cosmetic dental treatments there is. It's a mainstay of cosmetic dentistry in Harmondsworth, delivered under proper clinical supervision. The timescale ranges from a single 90-minute visit to a fortnight of overnight tray wear.
Whitening Options Available in Harmondsworth
In-chair (laser/light-activated) whitening happens in a single visit: a strong hydrogen-peroxide gel is light-activated for immediate change, usually lifting the shade several grades in one sitting.
Take-home tray whitening uses custom trays and professional-strength gel worn daily (30 minutes to overnight) over 2–4 weeks. It builds a gradual result with less sensitivity than in-chair treatment.
Combined whitening blends both approaches: immediate lift in the chair, then home trays to fine-tune and sustain the colour.
Over-the-counter kits are the weakest option by a wide margin — useful only for very minor upkeep, never for a real shade improvement.

How Tooth Colour Is Measured
Dental professionals in Harmondsworth use the VITA classical shade guide to record tooth colour, running from A1 (lightest) to C4 (darkest). Most natural teeth sit between A2 and B3, and professional whitening typically lifts 4–8 grades.
Not all teeth respond equally. Intrinsic staining from tetracycline or fluorosis whitens poorly, yellow tones respond best, and grey tones least. Crowns, veneers and fillings don't change colour at all, which can create mismatches to plan around.
