Teeth Whitening in Sidcup

Professional teeth whitening is one of the most popular cosmetic dental treatments there is. It's a mainstay of cosmetic dentistry in Sidcup, delivered under proper clinical supervision. Results can appear in a single in-chair session or build gradually over two to three weeks at home.

Professional Whitening Choices in Sidcup

In-chair (laser/light-activated) whitening happens in a single visit: a strong hydrogen-peroxide gel is light-activated for immediate change, usually lifting the shade several grades in one sitting.

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 (an in-chair session followed by take-home top-ups) is often recommended in Sidcup 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.

Managing Sensitivity After Whitening

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.
