For a brighter smile, professional whitening is a well-evidenced, non-invasive first step. In Underhill it is a common request, and results go well beyond what a supermarket kit can manage. Some patients whiten in one appointment; others prefer the slower, gentler take-home route.
Sensitivity, Aftercare and Keeping Results
Some patients feel sensitivity during whitening, particularly in-chair. Using a potassium-nitrate or stannous-fluoride toothpaste for one to two weeks before treatment cuts this significantly, and a desensitising gel can be used between sessions.
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.

Whitening Options Available in Underhill
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 Underhill because it maximises the initial jump and lets you maintain the shade over time.
Over-the-counter kits are the weakest option by a wide margin — useful only for very minor upkeep, never for a real shade improvement.
