How Tooth Colour Is Measured
Dental professionals in Onllwyn 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.
Yellow-toned staining lifts most readily; grey and intrinsic staining (antibiotics, fluorosis) far less so. Existing restorations stay the same shade, so front-tooth crowns or fillings may need separate planning.
Whitening Options Available in Onllwyn
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 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.
