Dyson CameraJet: The only toothbrush with a camera and a jet

The press release includes an image of a person brushing and looking at an image of their teeth on a phone. If you are actively brushing with toothpaste, the quality of the image will likely be as good as an unprepped colonoscopy.

It’s unlikely to yield any actionable information, other than scratching the pimple-popping gross-up itch.

On second thought, I am now half-expecting a home colonics device from Dyson. Easy setup… just lay down on your side in your bathtub.

> unprepped colonoscopy

That is a phrase I didn't have on my HN bingo card for the day.

piskov•42m ago
That’s why they developed a special toothpaste with less foaming (see the presentation video on youtube)
warkdarrior•42m ago
Plot twist: you can use the same device for mouth and colon cleaning.
ricardobeat•9m ago

    > This includes a proprietary non-foaming toothpaste, formulated without SLS (a common foaming agent)
    to help keep foam out of the way so the camera can see clearly and support Gap Optical Targeting™,
    alongside a low-foaming mouthrinse formulated for use with the precision jet
general_reveal•1h ago
Toothbrushes are a crappy device. I’ve seen some stuff lately that’s like a whole mouth brush, like a mouth guard. With a small pipe to the mouth guard feeding water, you can pretty much car wash your mouth every morning in 60 seconds. Sloshing water around in your mouth often creates way more pressure allowing water to go through the gaps in your teeth (cleaning them). But the waterpik sellers will convince you that isn’t true.

That’s the problem with highly skillful people that follow tradition. I’m sure the engineers are brilliant behind this (camera toothbrush designers), but they are still following tradition of this old idea.

Anyways. Sometimes you have to trust that you are well beyond tradition and are free to redefine all rules. Be fearless.

cenamus•33m ago
That whole mouth brush is also crazy exspensive, while I'd assume Philips' Sonicare line is well and profitable
boguscoder•25m ago
Whole mouth brush was a gimmick for almost two decades if not more, maybe these days its more adequate but I can only imagine what it could do to gums. Doctors can’t wait..

Hmm, they didn't go with CamJet..

What a stupid design. The jet stream can't even reach last back teeth.
nosioptar•34m ago
It wouldn't be a dyson without a shitty design.

The only dyson products I've used that didn't suck were their vacuums. (To be clear, their vacuums are shit and do not suck as well as even a cheap shark.)

I have a Waterpik Fusion 2.0

Sometimes I’ll add mouthwash or hydrogen-peroxide to the tank, it works well. Usually I start with a quick rinse, then a brush with the flosser on, then a finishing brush with the flosser off.

I see this and am unsure if it’s over-engineering a less effective solution. It’s neat, but I can’t say it excites me; am curious to see reviews and comparisons. The form factor does seem a bit odd though, visually it’s mediocre imo.

KPGv2•43m ago
I had some deep-ish gum pockets and switched to this pattern, and many of them resolved over a year without intervention:

0. tongue scraper 1. brush with normal toothpaste 2 min 2. floss 3. mouthwash 4. rinse 5. brush with a dry toothpaste that you don't rinse

I started to treat it like an important health step, less a chore. Like exercise or cooking healthy food instead of buying shit takeout.

bryanlarsen•12m ago
I just hit 6mm in one location. I have 4 months to avoid an intervention. Do you have a source / more info?

Thought I read elsewhere that if these get dirty they are essentially blowing dirty water into your gums, which can cause health problems

tools like this almost need the same level of sanitization you would see at the dentist.

other than that, I am very interested

piskov•41m ago
Don’t get it dirty
vel0city•17m ago
You're most likely using it in the same room where you poop, probably storing it next to a basin where you wash your dirty hands, and putting it in one of the dirtiest places in/on your body daily. It gets soaking wet hopefully twice daily.

I hate to break it to you, but it will get dirty.

feverzsj•36m ago
Qualified product should use antimicrobial plastic. You still need to disinfect it using mild disinfectant like iodophor.

I don’t even see how you can share direct to TikTok with this? Or have they got their own social network for toothbrushing? Can I use this to talk with someone using the Dyson ActiveDouche?

100K Pixel lol I guess 0.1MP doesn't sound impressive

Idk that is kind of trippy to see your own teeth in real time as you brush them

sdcfgy•19m ago
Meh. My toothbrush engine has around 100 trillion pathways in the neural network and sophisticated vision and motor capabilities.

Also it didn't push Brexit for years then piss of to Singapore.

ihumanable•17m ago
I appreciate that whoever is approving naming at Dyson doesn't care about making boring names.

- Pencil Fluffycones

- Ball Animal 3 Extra

- V16 Piston Animal Submarine

These are real product names that they were happy to ship. I like that they ship these absurd sounding names.
