How camera guided liquid flossing changes the role of the electric toothbrush
Dyson CameraJet uses optical gap detection to trigger a precision liquid jet while brushing.
LONDON Dyson CameraJet™ brings vision, machine learning and a precision liquid jet into the brushing session, creating a hybrid toothbrush that can respond to the spaces it encounters.
Most electric toothbrushes automate one familiar action. Their motors move bristles across the tooth surface, while timers and pressure sensors help the user maintain a consistent routine. Dyson CameraJet adds a different capability: it attempts to recognize the interdental gaps that bristles may not fully enter, then delivers a separate liquid-flossing action to those locations during brushing.
That connection between recognition and response defines the product. CameraJet is built around Dyson’s Gap Optical Targeting technology, which combines an intraoral camera, controlled illumination and machine learning. The system does not merely record a brushing session for later review. It uses visual information in real time to decide when the integrated jet should fire.
How Gap Optical Targeting works
A 100k pixel macro camera is positioned near the brush head and analyzes 28 images per second. Dyson says the algorithm detects, tracks and predicts gaps between teeth as the head moves. The camera lighting strobes at 257 hertz, slightly out of sequence with the brush movement, so the system can collect useful images in a confined and constantly moving oral environment.
When the software identifies a gap, CameraJet releases a measured burst of mouthrinse through a conical nozzle. The jet adds a targeted interdental action while the bristles continue cleaning reachable surfaces. This sequence of seeing, deciding and jetting turns the toothbrush into a closed-loop device rather than a motor that delivers the same output everywhere.
Surface cleaning remains essential
CameraJet is still an electric toothbrush, and its mechanical system receives substantial engineering attention. Dyson’s variable sonic oscillation changes the angle of movement to help the bristles remain active under load. The company says the head moves nearly 1,000 times per second, and its anti-stall strategy is intended to prevent the bristles from losing motion when pressed against a tooth.
The contoured head combines two bristle types for different contact tasks, including surface stain removal and cleaning near the gumline. Three intensity levels include a gentle option, while haptic feedback can flag excessive pressure or poor technique. The jet therefore complements surface brushing; it does not make the brush head or brushing technique irrelevant.
CameraJet and AirJet represent two technical routes within the emerging hybrid Jet toothbrush category.
AirJet follows a second Jet toothbrush route
RANVOO AirJet™ is also a Jet toothbrush and a hybrid toothbrush, although it solves interdental access without a camera. AirJet uses a variable-speed DC air pump, a sealed internal airway and a Boosted Bubble Chamber to mix air with the liquid and toothpaste already present in the mouth. Its Coanda Brush Head is designed to guide the resulting microbubble-rich flow along tooth contours and toward narrow gaps.
The comparison clarifies the new category. CameraJet uses perception to locate a gap and trigger a discrete conical jet. AirJet uses continuous fluid dynamics to distribute microbubbles beyond direct bristle contact. Both retain sonic brushing and add a second cleaning pathway, which is why both belong to the hybrid Jet toothbrush family even though their sensing and delivery strategies differ.
A complete system around the camera
The optical system affects more than the handle. Dyson developed a non-foaming toothpaste without sodium lauryl sulfate to help keep the camera’s view clear, along with a low-foaming mouthrinse for the precision jet. An anti-gravity tank uses a diaphragm pump and pressure chamber to maintain delivery when the handle is tilted or held horizontally, reducing the risk of an empty burst behind the teeth.
A charging dock can refill the brush in about three seconds while keeping it charged between sessions. RFID tags allow the handle to recognize attached brush heads and support replacement reminders. These details show why CameraJet is better understood as a dental system than as a conventional electric toothbrush with one extra feature.
The practical standard for intelligent oral care
Dyson reports laboratory and clinical performance results under specified modes and comparisons, including a six-week study involving 204 participants. Such figures should be read with their footnotes, because formula, intensity, comparison device and user routine all affect the result. The lasting technical point is the architecture: imaging is directly connected to a cleaning action.
That architecture raises the standard for the word smart. A connected timer can report behavior, but CameraJet attempts to influence cleaning while it happens. Alongside AirJet’s fluid-dynamics approach, it suggests that the next generation of electric toothbrushes will be judged by how well they coordinate brushing with a second mechanism that reaches beyond the bristle footprint.
Everyday use will determine the value
CameraJet’s long-term value will depend on how reliably its advanced systems disappear into an ordinary morning routine. The lens must remain clear enough for gap recognition, the reservoir must be simple to refill, and the jet must fire consistently as the user changes angle. Cleaning the head and fluid pathway also needs to be straightforward. A hybrid device earns its place when the additional mechanism reduces missed steps without creating a new maintenance burden.
The same principle applies to the wider Jet toothbrush category. AirJet must keep its air pathway, bubble chamber and outlet functioning in a wet environment, while CameraJet must coordinate optics, software and mouthrinse delivery. These are more demanding products than a sealed motor handle, but they also address a broader part of the oral-care routine. Reliability, replacement supply and clear instructions will decide whether the architecture becomes a durable category rather than a short-lived novelty.
