Whitening supplied by a registered dental professional uses far stronger gel than anything sold over the counter. Practices in St John tailor the concentration to your natural shade rather than a one-size-fits-all gel. Depending on the method, you'll see change immediately or across a short take-home course.
Professional Whitening Choices in St John
In-chair (laser/light-activated) whitening is done at the practice in one 60–90 minute appointment. A high-concentration gel is applied and activated with a light or laser, giving immediate results — typically a 4–8 shade lift, depending on your starting point.
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 St John 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.

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.
Sensitivity, Aftercare and Keeping Results
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.
