Dentist-led whitening is a safe, effective way to lighten tooth shade by several grades. It's a mainstay of cosmetic dentistry in Cosmeston, delivered under proper clinical supervision. Some patients whiten in one appointment; others prefer the slower, gentler take-home route.
Professional Whitening Choices in Cosmeston
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 uses custom trays and professional-strength gel worn daily (30 minutes to overnight) over 2–4 weeks. It builds a gradual result with less sensitivity than in-chair treatment.
Combined whitening blends both approaches: immediate lift in the chair, then home trays to fine-tune and sustain the colour.
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.

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 Cosmeston patients, with whitening moving them several grades lighter.
Response depends on the cause of the staining — surface and yellow discolouration whiten well, developmental and grey staining resist it, and any crowns or composite won't shift, so mismatches are worth discussing first.
