For decades, the standard electric toothbrush recipe has remained largely unchanged: add a motor, vibrate or rotate a brush head at high speeds, and leave the rest of the heavy lifting to the human holding the handle. Sir James Dyson and his team of engineers at Dyson, however, have decided that oral hygiene is overdue for an aerospace-grade overhaul.

Unveiled at an event in Paris, the Dyson CameraJet™ is a $499 USD smart oral care system that fuses high-speed computer vision, real-time machine learning, and precision fluid mechanics into a single bathroom gadget. Built over six years by a team of 661 engineers and dozens of dental professionals, the CameraJet aims to automate the single most neglected step in daily oral hygiene: flossing.

The Tech Inside: Computer Vision Meets Fluid Dynamics

At the core of the CameraJet is a tiny, 100,000-pixel macro lens camera mounted on the neck of the brush handle, directly below the brush head. Accompanied by a custom strobing light that pulses 257 times per second, the camera acts like a miniaturized medical endoscope operating inside your mouth.

Rather than simply recording your molars, the camera powers Dyson’s Gap Optical Targeting™ system. Driven by an onboard processor executing 16 million lines of code, a proprietary machine-learning algorithm scans the terrain of your teeth at 28 frames per second. Trained on a dataset of over 470,000 dental images, the AI identifies, tracks, and predicts the exact moment the brush passes over an interdental space.

Within 100 milliseconds of spotting an interdental gap, the device triggers a micro-burst of liquid flossing spray straight between the teeth.

The Anti-Gravity Liquid Reservoir

To feed those rapid liquid blasts, Dyson abandoned traditional “straw-in-a-cup” liquid tanks, which tend to draw air pockets when held sideways or upside down.

Instead, the handle houses an internal 12.5 ml Anti-Gravity Tank connected to a diaphragm pump and pressure chamber. This setup delivers controlled, uninterrupted conical jets of mouthwash regardless of the angle at which you hold the brush. The conical jet pattern is intentionally broader and uses lower pressure than conventional needle-thin water flossers, cleaning plaque effectively while remaining gentle on delicate gum tissue and enamel.

Overcoming Mechanical Stalling & Acoustic Noise

Beyond its automated jet system, Dyson has re-engineered the mechanical movement of the bristles. Traditional electric toothbrushes can suffer from “stalling”—a phenomenon where applying pressure against uneven tooth contours slows or stops the bristle sweep.

 └──────────────────────────┘       └──────────────────────────┘

• Variable Sonic Oscillation: The motor dynamically adjusts its angle of motion as you brush. This continuous variation prevents bristles from jamming against surfaces, driving up to 69% higher plaque removal in hard-to-reach posterior areas compared to standard high-end sonic toothbrushes.
• Sonic Dampening: The interior of the brush head incorporates specialized acoustic dampening chambers to reduce harsh mechanical vibrations and high-pitched motor whine.

The Complete Consumable Ecosystem

To maintain clear optical visibility for the camera, standard off-the-shelf toothpaste won’t work. Thick white foam generated by traditional Sodium Lauryl Sulfate (SLS) surfactants would obscure the macro lens within seconds.

Dyson has created its own line of specialized dental consumables, available in paired Spearmint and Ginger Mint flavors designed to blend seamlessly during brushing.

Furthermore, every brush head includes an embedded RFID tag. The brush handle reads the tag to verify authenticity, monitor total brush cycles, and notify you via the handle interface or mobile app when the head needs replacement.

Connectivity, Privacy, and the MyDyson App

The CameraJet connects to home networks using 2.4 GHz Wi-Fi and Bluetooth. Through the companion MyDyson™ app, users can access a live camera stream from inside their mouth, providing a real-time endoscopic view of areas usually hidden from bathroom mirrors.

The app also provides 3D coverage mapping, tracking which surfaces of your teeth have been cleaned and highlighting missed spots.

Privacy First

Addressing concerns about mounting a Wi-Fi-connected camera inside a private home setting, Dyson specifies that the camera operates under strict hardware-level constraints:

1. The camera sensor is powered only during active live-viewing sessions or during automatic gap-jetting cycles.
2. Zero images or video feeds are recorded, saved to local storage, or uploaded to external cloud servers. All computer-vision analysis is executed locally on the handle’s onboard processor.

Is $500 for a Toothbrush Worth It?

At $499 USD, the Dyson CameraJet sits well above existing flagship electric toothbrushes like the Philips Sonicare Prestige 9900 or Oral-B iO Series 10.

While the upfront cost—plus the recurring subscription expense of proprietary toothpaste, mouthwash, and RFID brush heads—is steep, the technology targets a fundamental health issue: according to global dental studies, nearly 90% of adults fail to floss daily, leading directly to interdental plaque accumulation and gum disease. By automating flossing into a standard two-minute brushing routine, Dyson is betting that consumer convenience will outweigh the high price tag.
