Guides and cost comparisons

Professional teeth whitening uses higher-concentration hydrogen peroxide or carbamide peroxide gels than over-the-counter products. In-chair treatments like Philips Zoom use light activation for results in about an hour, while take-home kits use custom trays worn overnight for 1–2 weeks.
Most adults with healthy teeth and gums are suitable for professional whitening. It works best on yellowed teeth from aging, food, or drink stains. Crowns, veneers, and fillings won't change colour with whitening. Your dentist will assess suitability and recommend the best system.
Professional whitening results typically last 1–3 years, depending on diet and habits. Coffee, red wine, and smoking can reduce longevity. Many patients use top-up kits every 6–12 months to maintain their shade. Custom home trays make ongoing maintenance straightforward.
Professional whitening is safe when performed by a GDC-registered dentist. Temporary sensitivity during or after treatment is common but usually resolves within a few days. Desensitising toothpaste used before treatment can help minimise discomfort.
Westminster has 0.4 NHS dentists per 1,000 residents — well below the London average. Most practices operate on a private or mixed basis.
