Teeth Whitening

Teeth whitening is a cosmetic treatment that lightens the natural colour of teeth and lifts staining caused by food, drink, smoking, or ageing. A dentist applies a peroxide-based whitening gel — used in the practice or in custom-made trays at home — to safely brighten the smile by several shades. Results are not permanent and may need topping up.

Professional teeth whitening typically lasts from several months up to around two to three years. How long results last depends on your diet and habits, as tea, coffee, red wine, and smoking cause staining to return faster. Many people use occasional top-up treatments to maintain the shade.

Teeth whitening is safe when carried out or prescribed by a registered dental professional, who will check your teeth and gums are healthy first. In the UK it is illegal for anyone who is not a dental professional to whiten teeth. Some people experience temporary sensitivity, which usually settles quickly.

Teeth whitening is considered a cosmetic treatment, so it is not available on the NHS and is offered privately. Practices may provide in-surgery whitening, custom take-home trays, or a combination of both. Prices vary, so it is worth asking the practice for a quote.
