Understanding Tooth Shade — The VITA Scale
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 Pentwyn 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.
Whitening Options Available in Pentwyn
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 (an in-chair session followed by take-home top-ups) is often recommended in Pentwyn because it maximises the initial jump and lets you maintain the shade over time.
Over-the-counter kits are the weakest option by a wide margin — useful only for very minor upkeep, never for a real shade improvement.
