Comments
The water jet ruined my teeth. I would not advise anyone to use them.
Edit: here are some anecdotes https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/d...
Edit 2: It might be that I didn’t maintain it properly and the water reservoir was building up bio film over period of time and actively distributing bacterial to my gums.
Never been less satisfied than having bought a Dyson vacuum. Cheap plastic construction
I highly recommend this technical analysis of the advantages of the smart toothbrush, it should help the sceptics.
"Clinically tested
Dyson CameraJet™ is clinically proven to be more effective in improving gum health by removing and preventing plaque buildup.² Vs a manual tooth brush. "
So they didn't dare compare it against a 20 EUR Braun Oral B?
Dyson seem to be the champion of turning a cheap effective device that's well understood into the same device but an order of magnitude more expensive. Are people still buying it?
Am very happy with my Panasonic water flosser (especially now its chargeable via USB Type-C), great for gum health and far more pleasant than regular dental floss for me personally. Besides the Dyson typical pricing, one concern I have from the get-go is the tank size, seems to be a tenth vs the 200ml the Panasonic packs.
At least I do use all of that to properly clean every area and if they do it simultaneously to regular 2min+ brushing, I'm interested to see how that works in terms of water usage. Likely why they got the camera, for short bursts, looking forward to read some papers on how well that truly works vs a consistent stream.
Besides that, I personally always liked the totally round, smaller Oral-B heads vs Philips and other electrical toothbrushes, mainly cause that's what I grew up on. Seems Dyson is somewhere in the middle, smaller than most but not quite fully round.
Price as mentioned is a lot, but not unprecedented for those just buying the iO Series 10 or Philips equivalent + an Aqua flosser. Though there is no real reason to go for the 10, e.g. 8n is identical even in the superfluous comfort features at often less than 50%.
They gave it the same design language as their vacuums, and honestly I don't think they want people making that association. It's kinda ick.
lol, nice to see some engineering company building outlandish product. Not everything needs mass appeal, this is not for me but maybe some one finds this interesting
Absolutely crazy concept. But looks like they actually threw something decent together. I'd wager the bulk of problems people face with teeth come from poor flossing, this makes it effortless to avoid that.
I've owned water jets, the ones I've had suck. I always end up going back to dental floss. These days string on a plastic holder which I hate because it feels so wasteful to have all that single use plastic, but they are just so effective and I hate the manual wrapping of string, so I accept the wastefulness reluctantly.
This product potentially hits home with what I'd want from an effective waterjet, and it also comes with a brush on top.
The price is high, that's for sure, but I'm guessing they aren't aiming at the average electric tooth brush market, more like a competitor to the oral b io series 9 segment. And sure they are quite a bit above that price point, but they got a lot more of a solution backing the price.
"AI toothbrush" was not on my 2026 bingo card.
Surprisingly, $30 for two replacement heads is comparable to other electric toothbrushes (not counting third-party bulk knockoff replacements, which I have been using for years without issue). The RFID reader might force you to buy the official replacements, though.
Dear Hackernews:
It is not good security practice to publish your random word passphrases as the title of an article.
Thank you for your time
Curious how much replacement heads will cost if they're going to stick an RFID in every single one. Surely there's a cheaper solution to track when you switched heads.
I would happily spend $500 on this if it really did what it claims to. Maybe.
But I find myself a bit skeptical. Would love to see some long-term third party testing on it.
Having once bought a girlfriend the $400 Dyson hairdryer, I tried to guess the price before I clicked the link, but I still guessed low.
500 bucks for a toothbrush, but could be some interesting angles. Always dreamed of removing plaque myself, future of robotic dentistry
I laughed out loud when I read the title, but the more I read about it, it actually sounds really cool. I know that is just their advertising and marketing jargon that is doing this but it does sound awesome... definitely not 500$ worth of awesome though
My dentist uses AI for X-ray analysis. I wish I remembered the name but the monitor was facing me and it was obvious. They also use some sort of fancy imaging tool that they run around my mouth to create a 3d image.
A purchasing decision for households: buy a $500 vacuum or a $500 toothbrush. Dyson competing with itself for limited consumer discretionary income on luxury purchases.
Does it significantly reduce cavities and/or gum disease? In other words, what's the effect of the AI water jet on dental health?
Water flossers with handheld tanks are already unwieldy. I can't imagine using one with the head vibrating, water coming out of my mouth, and I'm trying to view the inside of my mouth in an app. Replaceable battery though. $20 Sonicare can't do that!
Clever solution, but I am not sure I can see a matching problem
Do people on HN actually buy/like Dyson products?
My impression is they're actually way overpriced relative to their quality/value, and get away with it due to effective marketing and aesthetic design.
To be fair, I've never owned a Dyson product, but have used them, and they just seem meh at best.
Just really surprised to see a Dyson announcement get upvotes on HN.
Man marketing really screwed a great engineered product.
4k resolution mouth camera?? That's why we go to a dentist every 6 months because I wouldnt know wtf im looking at.
"Oh there's that canker sore I feel. Huh, at least I can see it"
Bruh, you don't need a camera for gap detection. Just stick an IR sensor, detect change in light. Boom, $0.05.
I use the cheapest toothbrush I can buy with homemade toothpaste and haven't had a cavity since middle school. The only dental problem I've had in my adult life was my tooth with the filling getting cracked in a car wreck.
Technology marketing continues to suck wealth away from consumers.
Wow they started working on this in like 2014 or something. Can't believe it's actually been released!
Not really excited for a $500 toothbrush, but this should have an awesome impact on the rest of the market.
Putting the word "camera" in the name seems pretty dumb, but who knows? Maybe I'm the dumb one.
For $500 I want it to brush my teeth for me, like the robo arm from "The Jetsons".
This page must be one of the worst product image and video displays I've ever seen. Videos are probably for ultra-ADHD Gen Z kids.

The HN title makes it sound like Toothbrush is their brand, and with the appropriation of common terms for the sake of the brand, I bought it.
I would be disinclined to use it. It reminds me of the Astral Codex Ten Article about the Midjouney Scanner https://www.astralcodexten.com/p/preliminary-thoughts-on-the... , as well as those who've had problems with AirPods. https://discussions.apple.com/verify-human/verify.html?next=... (42 pages) What sounds the most amazing in a press release is often not the most medically sound.
Edit: it's hard to find clear info on the risks of improperly using an electric toothbrush or even on overbrushing, let alone the Dyson one, in part because a lot of search results are blogspam. Hopefully if the Dyson one is stronger, they don't use that to give it a default that is too much pressure, whether of water or moving bristles. I don't know that water pressure would cause enamel to come off. As for pressure using bristles, there is a point of pressure at which the cleaning effect stops increasing, and it is better not to go beyond that. Right now it's unclear to me whether the Dyson toothbrush works especially well or not.
This is the gold standard of how to properly apply AI to an existing product like a toothbrush, with significant engineering quality that actually makes it better.
That is what I call not "slop".

Notice they don't include ultrasonic and rotating brushes in that statement.
