Dyson CameraJet — The $499 Electric Toothbrush With a Camera Hidden Under the Bristles

When I first heard that someone was putting a camera inside an electric toothbrush, I assumed it was just another spec-chasing gimmick. But once I looked into how it actually works, it made a lot more sense. The Dyson CameraJet uses a 1mm camera tucked under the bristles that captures 28 frames per second to spot gaps between your teeth, then fires a jet of mouthwash at that exact spot within 100 milliseconds. What really caught my attention was that Dyson even reformulated a foam-free toothpaste just so it wouldn't block the camera's view.

🔍 Why I'm Interested

An approach where the toothbrush "sees" and decides

Until now, electric toothbrushes have basically just vibrated in preset patterns and told you the time with a built-in timer. This one is on a different level — it actually reads the gaps between your teeth with a camera and precisely targets mouthwash only where it's needed. The idea of a device making that judgment call for you, handling the gaps you can't see yourself, is genuinely interesting.

The obsessiveness of redesigning the toothpaste just for the camera

Apparently, if foam covers the lens, the camera becomes useless — so Dyson went ahead and developed a dedicated foam-free toothpaste. Redesigning the entire consumable ecosystem just to make one camera work properly feels very on-brand for Dyson.

The 3-second rapid-charge dock

The included dock, which reportedly fills the tank (presumably the mouthwash reservoir) in just 3 seconds, also stands out from a practical standpoint. If the design requires refilling regularly, fast charging like this could end up being a major factor in day-to-day satisfaction.

🤔 What Gives Me Pause

The $499 entry barrier

That's a steep price for an electric toothbrush. Even accounting for the camera sensor and precision spray system, it's several times pricier than a standard electric toothbrush, which could be a real barrier for a lot of people.

Dependence on proprietary toothpaste

Needing a foam-free proprietary toothpaste for the camera to work also means being locked into buying consumables within Dyson's ecosystem going forward. I won't know how inconvenient it is to give up my usual toothpaste until I actually try it.

Lack of battery and durability information

The article doesn't specify exact battery life or long-term durability. Given how much precision sensor hardware is packed in, I'm curious how it holds up — and what the failure rate looks like — over extended use.

🎯 Final Verdict

Putting a camera inside an electric toothbrush seemed excessive at first, but once I understood how it works — reading the gaps between teeth and firing mouthwash precisely at that spot — it started to feel like a genuinely well-reasoned design. The fact that Dyson even reformulated its toothpaste just to keep the camera's view clear shows real attention to detail.

That said, the $499 price and the dependence on proprietary toothpaste are clear barriers to entry. Unless you're someone who's truly meticulous about oral care, it might be worth waiting for official reviews and real-world durability data before making the call.
