How Tooth Colour Is Measured
Colour is tracked on the VITA scale — A1 at the light end through to C4 at the dark. Untreated teeth usually fall around A2–B3 in Old Knebworth patients, with whitening moving them several grades lighter.
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 Old Knebworth
In-chair (laser/light-activated) whitening delivers the fastest visible result — one supervised session with professional-strength gel, most patients leaving 4–8 VITA shades lighter that day.
Take-home tray whitening involves bespoke trays and dentist-supplied gel worn over roughly a fortnight — excellent, controllable results at your own pace.
Combined whitening pairs a fast in-chair kick-start with trays for maintenance — a popular route in Old Knebworth for people who want quick results that last.
Over-the-counter kits are legally capped at very low peroxide levels and can't match professional results. They suit minor maintenance at best, not a genuine shade change.
