Dyson CameraJet Toothbrush Faces Scrutiny Over Efficacy and Practicality
The £419 device combines brushing, flossing, and mouth rinsing, but dentists raise concerns about its fluoride-rinsing mechanism and cleaning effectiveness.
Dyson's new £419 CameraJet electric toothbrush, which integrates a camera, flosser, and mouthwash dispenser, is facing questions from dental professionals regarding its cleaning efficacy and practical design.
The device aims to simplify oral hygiene by combining brushing, flossing, and rinsing into a single function. James Dyson stated the camera helps the brush 'see' gaps between teeth to deliver a jet of mouthwash, addressing the common reluctance to floss.
However, some dentists express concern that the device's mouthwash function may rinse away the fluoride from toothpaste, diminishing its protective benefits. One dental professional noted that rinsing is generally advised against for at least 15 minutes after brushing to allow fluoride to take effect.
Beyond the potential impact on fluoride efficacy, practical challenges have also been reported. Users have described difficulty in using the device, with mouthwash often spattering due to issues with the camera lens becoming obscured by foam. Refills for Dyson's proprietary low-foam toothpaste and mouthwash cost £9.99 and £8.49, respectively, although other low-foam options can be used.
Dr. Daniel Sutcliffe, founder of The Bespoke Dentist, described the CameraJet as primarily a toothbrush with a camera, suggesting it does not replace traditional flossing or interdental brushes. He noted that while the camera can be a valuable tool for patients to visualize gum inflammation, the device's claim of being 13 times more effective at improving gum health was measured against a manual toothbrush, a comparison he deemed irrelevant for consumers considering a £420 purchase.
Sutcliffe indicated that plaque removal requires physical contact, which the CameraJet's water jets may not provide for stubborn plaque. He suggested that testing the device against a high-quality electric toothbrush and interdental brushes over a significant period would offer more meaningful results.
Practicality is another point of contention. The device is described as large, and its charging dock requires a USB-C adapter for typical bathroom plugs. The mouthwash reservoir must be filled from the base unit, making it unsuitable for travel. Despite its high price, Dyson's CameraJet is positioned below some high-end Oral-B and Philips Sonicare models, which retail for up to £800 and £599.99 respectively, though these are often available at lower prices.
The journalist who tested the device concluded that it felt designed without sufficient input from dentists or end-users, recommending regular dental hygienist visits and the use of interdental brushes as a more effective alternative.
