A new electric toothbrush priced at £340 is hitting the market, but experts question whether such an expensive device is necessary when a £6 model can do the same job. The Oral-B Genius X uses artificial intelligence and sensors to track brushing habits, yet dentists say basic electric toothbrushes are equally effective at removing plaque.
According to a 2014 review of 56 studies, electric toothbrushes reduce plaque by 11% after one to three months and 21% after three months, compared with manual brushes. They also lower the risk of gingivitis. However, the review did not find significant differences between high-end and budget models.
Despite improvements in dental health over the past 50 years, one in three Britons still fails to brush twice daily, and the average brushing time is just 45 seconds—half the recommended two minutes. Many also brush too aggressively, damaging gums and enamel.
Dr Mervyn Druian from The London Centre for Cosmetic Dentistry recommends electric toothbrushes for most patients, but says a £6 Colgate 360 Sonic Power Toothbrush can be just as effective as a £340 model. The key is proper technique and consistency, not price.
