Whitening supplied by a registered dental professional uses far stronger gel than anything sold over the counter. Practices in Pen-onn tailor the concentration to your natural shade rather than a one-size-fits-all gel. The timescale ranges from a single 90-minute visit to a fortnight of overnight tray wear.
Whitening Options Available in Pen-onn
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 Pen-onn 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.
Managing Sensitivity After Whitening
Transient sensitivity is normal and short-lived. Pre-treating with a sensitivity toothpaste, and avoiding very hot or cold drinks for a day or two afterwards, keeps it manageable for most people.
Whitened enamel re-stains fastest in the first couple of days, so ease off coffee, tea and red wine. With sensible maintenance the shade holds for one to two years before a quick refresh.
