Whitening Options Available in Cog
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 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 (an in-chair session followed by take-home top-ups) is often recommended in Cog because it maximises the initial jump and lets you maintain the shade over time.
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.
The VITA Shade Guide Explained
Dental professionals in Cog 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.
