Ways to Whiten Your Teeth in Belsize

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 blends both approaches: immediate lift in the chair, then home trays to fine-tune and sustain the colour.

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.

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.

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.
