Professional teeth whitening is one of the most popular cosmetic dental treatments there is. In Merrion it is a common request, and results go well beyond what a supermarket kit can manage. Depending on the method, you'll see change immediately or across a short take-home course.
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.
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.

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.
Whitening Options Available in Merrion
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 Merrion 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.

Why is it illegal for beauty salons to whiten teeth?

Beauty salons or non-dentists offering whitening are acting illegally, and treatment without a proper dental check carries real risks to teeth and gums.
