The electric toothbrush market has evolved dramatically over six decades, with luxury models now costing up to £600, particularly following Dyson's entry with a £419.99 camera-equipped device. This expansion reflects growing public interest in oral health, partly driven by emerging evidence linking gum disease to serious conditions including diabetes, cardiovascular disease, and Alzheimer's. Premium toothbrushes have become bathroom status symbols, yet this affluent market exists alongside an ongoing dental crisis in the UK.

In the UK, 59% of adults now use electric toothbrushes, generating £361 million in annual sales including replacement heads, with prices ranging from approximately £25 to £599.99. Whilst dentists recommend rechargeable electric models over manual ones, leading practitioners emphasise that there is no robust research demonstrating that expensive brushes clean plaque more effectively than cheaper alternatives. The market's expansion reflects increased consumer consciousness about dental wellness rather than proven superiority of high-end products.
