Dyson has expanded into a new category of personal care by introducing the CameraJet, a hybrid device that combines an electric toothbrush and a built-in flosser. While the company is no stranger to unusual multi-purpose appliances, having previously released the short-lived Dyson Zone air-purifying headphones, this latest combination of oral care technologies feels considerably more practical, even if embedding a camera in a toothbrush sounds unusual.
The CameraJet functions primarily as a standard electric toothbrush while integrating a fluid delivery system that shoots mouth rinse directly into the interdental spaces as you clean. The device determines precisely when the brush head passes over a gap requiring a rinse through the use of an integrated endoscope camera. This sensor analyzes 28 images per second, triggering targeted bursts of liquid as the user moves the brush across their teeth.
Referred to by Dyson as the Gap Optical Targeting system, the mechanism relies on a macro-lens camera paired with a machine learning algorithm. This software was trained on an extensive dataset of 470,000 dental images gathered over the six years the company spent developing the product. According to the manufacturer, the entire process takes place within 100 milliseconds, allowing the camera to identify a gap and flush it with rinse while normal brushing continues.
The fluid jet itself incorporates specialized engineering designed to improve plaque removal. Dyson explains that the device utilizes a conical jet configuration, which it claims removes plaque more effectively over a wider surface area than the needle-type jets found in traditional standalone water flossers. By operating at a lower pressure, the cone-shaped stream is designed to be gentler on both gums and tooth enamel.
To evaluate the efficiency of the design during development, Dyson partnered with the National University of Singapore's Faculty of Dentistry to create a proprietary proxy plaque. This methodology enabled designers to test and refine the toothbrush's cleaning capabilities in a laboratory setting without requiring lengthy clinical trials for every minor iteration.
Positioned directly beneath the brush head is a small reservoir capable of storing 12.5 milliliters of alcohol-free mouth rinse. A dedicated diaphragm pump and pressure chamber ensure that the fluid jets maintain consistent output regardless of the orientation of the brush, a feature Dyson highlights as an advantage over competing models that can lose performance when tilted. An accompanying docking station refills the reservoir in three seconds via a button press, while also serving as a charger and countertop stand. A dedicated travel case is also included for portability.
The bristle head itself features a contoured shape engineered to maximize contact across a greater portion of the tooth surface, utilizing firmer inner bristles alongside softer outer bristles. An embedded radio-frequency identification or RFID tag tracks the number of cleaning sessions completed to notify users when a replacement is due. A softer alternative brush head is also available for individuals with sensitive teeth and gums.
In addition to these features, the device incorporates standard sonic oscillation, driving side-to-side vibrations to dislodge debris. The CameraJet utilizes a variable sonic oscillation system that adjusts the oscillation angle during use, a design choice intended to prevent the bristles from stalling when subjected to pressure.
These combined technologies culminate in Dyson's primary performance claim: that the CameraJet removes up to 69 percent more plaque in hard-to-reach areas than market-leading premium electric toothbrushes, based on laboratory testing of the brush-only variable mode.
Connectivity options include Bluetooth and Wi-Fi integration, allowing the toothbrush to sync with the MyDyson app. While the app is not required for daily operation, opening it enables users to view a live feed from the toothbrush camera as it sprays liquid into interdental gaps. Addressing privacy concerns, Dyson states that the camera operates exclusively when the live view is actively opened in the app or when the device is automatically scanning for gaps. The company emphasizes that images are neither recorded nor stored locally on the device or in the cloud.
Optional app features include personalized feedback, coverage mapping to track uncleaned areas, and a guided cleaning mode. Users can also switch from automatic targeting to a manual jetting mode if preferred.
Potential buyers must consider several additional factors before purchasing. True to the brand's pricing strategy, the CameraJet carries a retail price of $499. Available in blue and pink color options, the package includes a refill dock, two standard brush heads, and a charging cable.
Furthermore, standard toothpastes and mouth rinses cannot be used with the device. Dyson is introducing a proprietary non-foaming toothpaste designed to prevent foam from obscuring the camera lens, along with a low-foaming mouth rinse tailored for the system. Customers can opt into a subscription service for recurring deliveries of consumables, though third-party rinses and toothpastes are compatible provided they are free of sodium lauryl sulfate, a foaming agent.
Statistics indicate that approximately one in three adults in the United States reports daily flossing, and numerous studies show that individuals frequently spend less than one minute brushing, falling short of the two-minute duration recommended by the American Dental Association. By merging brushing and flossing into a single routine, Dyson aims to streamline oral hygiene, though real-world effectiveness remains to be seen as users test the camera-guided cleaning system.
