Professional teeth whitening is one of the most popular cosmetic dental treatments there is. Patients across Castlewellan choose it because the shade lift is calibrated to their teeth and sensitivity. Depending on the method, you'll see change immediately or across a short take-home course.
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.
Whitening Options Available in Castlewellan
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 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 Castlewellan because it maximises the initial jump and lets you maintain the shade over time.
Over-the-counter kits sold in shops are limited by law to weak gel concentrations, so they're fine for touch-ups but no substitute for dentist-led whitening.
