Dentist-led whitening is a safe, effective way to lighten tooth shade by several grades. Patients across Sarn choose it because the shade lift is calibrated to their teeth and sensitivity. The timescale ranges from a single 90-minute visit to a fortnight of overnight tray wear.

How Tooth Colour Is Measured
The VITA guide gives whitening an objective before-and-after in Sarn: most teeth start near A2–B3, and a course commonly achieves a 4–8 shade improvement.
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.
Professional Whitening Choices in Sarn
In-chair (laser/light-activated) whitening is done at the practice in one 60–90 minute appointment. A high-concentration gel is applied and activated with a light or laser, giving immediate results — typically a 4–8 shade lift, depending on your starting point.
Take-home tray whitening gives you custom-fitted trays to wear at home for a couple of weeks; the slower build tends to be gentler on sensitivity while reaching the same end shade.
Combined whitening blends both approaches: immediate lift in the chair, then home trays to fine-tune and sustain the colour.
Over-the-counter kits sold in shops are limited by law to weak gel concentrations, so they're fine for touch-ups but no substitute for dentist-led whitening.

It depends on your starting shade — most people see a 4-8 VITA-grade lift, but there's a genetic ceiling you can't whiten past. Yellow-toned staining lifts well; grey or intrinsic staining responds poorly.
