For a brighter smile, professional whitening is a well-evidenced, non-invasive first step. In Castell it is a common request, and results go well beyond what a supermarket kit can manage. Results can appear in a single in-chair session or build gradually over two to three weeks at home.

Professional whitening is legally restricted to registered dental professionals in the UK. Always verify that any clinic offering whitening treatment is registered with the General Dental Council before proceeding.
Managing Sensitivity After Whitening
Sensitivity is the most common side effect — usually a sharp, transient twinge with air or cold that settles within 24–48 hours. A sensitivity toothpaste used for two weeks beforehand noticeably reduces it.
For 48 hours afterwards, avoid intensely pigmented foods and drinks — coffee, tea, red wine, berries, tomato sauces — while the enamel is temporarily more porous. Results typically last 12–24 months before a short top-up restores the shade.
Ways to Whiten Your Teeth in Castell
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 pairs a fast in-chair kick-start with trays for maintenance — a popular route in Castell for people who want quick results that last.
Over-the-counter kits are the weakest option by a wide margin — useful only for very minor upkeep, never for a real shade improvement.
