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?
- RavlaAlvar 17d ago
  At least the big purifier is categorically better than competition

  And if you wait a few months, you will find several other alternatives in the market at a more reasonable price. I learned not to jump on the Dyson bandwagon with their vacuum cleaners.

    My wife, upon seeing the pictures of this ridiculous contraption I gleefully waved in her face, described it as "a Sonicare on a steampunk bender", so arguably there are already pretty good options.,
- jimnotgym 17d ago
  Of course they will. People buy rubbish like this all the time. Here I am in a hotel room with a Dyson fan, which simultaneously moves less air, and is more noisy, with a much more piercing tone, than my home fan with blades that I bought for £30 from screwfix. I'll be turning it off before I sleep... unlike the one at home.

    But it doesn't have any fan blades in it! Only an impeller with blades

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.

  I'm not that extreme, but I somewhat agree. I just want them to make square handle toothbrushes common again. It's impossible to get a good grip and torque on the newer rounded ones when your hands are wet and toothpasty or waxy from floss.

It feels too over-engineered, just to sound fancy and high-tech. People are just obsessed with some miracle silver-bullet device that automatically does everything. I'm using dental floss → water pick (just water, no mouthwash) → electric toothbrush → tongue scraper. Literally everything takes 4 min and cost less than the Dyson.

ok first thoughts - this is a cool, but ludicrously expensive toothbrush! Anyone who buys one is just flaunt their wealth when $2 gets you a manual version

500 bucks for a toothbrush, but could be some interesting angles. Always dreamed of removing plaque myself, future of robotic dentistry
- wkoszek 17d ago
  If this is doing better waterpik + toothbrush and perhaps has a long guarantee and leaves you with a 2x normal feeling every morning, I could see the appeal. I dropped $60 on Waterpic and it broke. So then I got a better Waterpik for $100+ but it was clunky unit with bigger water container that didn't fit in my small bathroom. And it broke. But I do like the feeling of electric toothbrush.
  - Oscalemor 14d ago
    Waterpik has been a fun and messy ride but beats the threading and daunting manual labour.
    - wkoszek 14d ago
      I haven't yet tried the units from Amazon where you connect the Waterpik to the faucet, but perhaps they could be good -- for me the problem has always been how small the water container was.
  - darksim905 17d ago
    an ultrasonic scaler is far better at removing plaque and build up than a waterpik. I find that a waterpik is only really best at areas where there is high crowding, or hard to reach areas behind molars, etc.
    - spidersouris 17d ago
      But dental scalers don't offer the advantages water flossers do for gums, do they? Plus, from whet I've read online, it seems that these devices need to be used after brushing, as opposed to water flossers which are used before brushing. And for dislodging food (especially with braces), water flossers remain the best tool.
heikkilevanto 17d ago
Clever solution, but I am not sure I can see a matching problem
- yndoendo 17d ago
  Problem is there are no good cameras for the OnlyFans subscribers that have a teeth and gums fetish. 4K is the solution that takes them deep inside. /s
  - iAMkenough 17d ago
    I wonder what stack they're using to stream live video from the toothbrush to the phone. I wonder whether the camera can still be activated when the toothbrush is sitting on your bathroom sink countertop, pointed at your shower.

Never been less satisfied than having bought a Dyson vacuum. Cheap plastic construction
- dml2135 17d ago
  I had the plastic trigger fail on mine. Took the whole thing apart and replaced it with a metal trigger from AliExpress. It’s been going strong since. I’m not usually a conspiracy theorist, but if I was a product engineer looking for a way to make my well-engineered product fail just after the warranty period was up, that trigger failure looked like a pretty good candidate. There was a specific piece of the plastic that looked like it was ostensibly there as a structural reinforcement, but it was clearly too short, and the trigger had cracked just past it. ifixit guide for the curious: https://www.ifixit.com/Guide/Dyson+V11+Trigger+Replacement/147481 https://www.ifixit.com/Guide/Dyson+V11+Trigger+Replacement/1...
- stuaxo 17d ago
  I had a dc03 animal for over 10 years, kept replacing bits.. this year replaced it with the modern equivalent as I didn't want a battery powered one. The new one just feels sort of flimsy in all sorts of ways, definite buyers remorse, the old one just felt indestructible + really powerful, this seems a bit crap.
- rebeccajae 17d ago
  I was given a V6 and I bought an adapter that lets me use my dewalt batteries with the vacuum. Kind of a cool party trick but I think they were like $600 new which is bonkers.
- IshKebab 17d ago
  Rubbish. All vacuums are plastic and Dysons actually use quite high quality plastic. When I worked there they were always really worried about Shark, because apparently they have better pick-up benchmark scores. I bought one recently. Absolute trash. It has some bullshit automatic power control thing that is on by default but just varies the power completely randomly. So every time you turn it on it takes about 5 seconds - on, low power, high power finally. Vs the Dyson where you just pull a trigger. Never again. Dysons are the best. Very expensive, but just buy the older models or refurbished. Also don't bother with the hair drier or the cold fans. Not worth the price. The hot fans might be I guess.

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/detail.cfm?mdrfoi__id=5427387&pc=EFS 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.
- Topfi 17d ago
  > 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. Not in any way knowledgeable on Dental Hygiene, so take this for layman's advice from someone who has used a water flosser for half a decade to positive effect: To anyone reading, please read the instructions in terms of proper usage, how to place it, etc., don't go full blast in the first few weeks and absolutely clean it according to the instructions. At least always empty the water fully and dry it out with the reservoir opened. Not saying this is what caused your negative experience, mind you. Again, Dental is not my field (Dentists, feel free to correct me if anything I wrote is wrong), but from my understanding and reading (I did read some papers when deciding to buy my first, cause of course I do my purchasing decisions on PubMed), some peoples gums seem to be simply more sensitive [0] to water flossers, even with proper device maintenance. In the end, always clear with your dentist. [0] https://pmc.ncbi.nlm.nih.gov/articles/PMC11180943 https://pmc.ncbi.nlm.nih.gov/articles/PMC11180943

  My oral irrigator is super important for my gums. Whenever I have a sensitive spot it some inflammation I can get it under control by irrigating the spot twice a day. It’s been years since I had bleeding gums. Before using the irrigator I constantly had problems with my gums.

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.

  dentists made up the 6 month rule. There's no evidence that it improves outcomes, for most people with healthy teeth, 24 months is fine: https://pmc.ncbi.nlm.nih.gov/articles/PMC7701991/ https://pmc.ncbi.nlm.nih.gov/articles/PMC7701991/

  Bit off topic, but if you suffer from canker sores, SLS (sodium lauryl sulfate) is a known contributor to that in some people (me included). It's a bit hard to find toothpastes without it that aren't also fluoride free, but they exist.
benatkin 17d ago
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-midjourney 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=/thread/250886390 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.

  Don't worry, they wouldn't lose the chance to trademark something silly like CameraJet™

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".

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.
- al_borland 17d ago
  $500 + $15/replacement head. That’s assuming you can even get them. Right now they are out of stock, and my bet is these will never be something you can just pick up at the grocery store. Any time I’ve bought something with frequently out of stock consumables, it’s been a mistake. It quickly falls out of favor.

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.

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.
- nephihaha 15d ago
  Dyson was good for some products in the 1990s. Their quality has fallen in recent years, and other companies have caught up with them in other regards such as vacuum cleaners.
- danudey 17d ago
  I borrowed a dyson vacuum once from a neighbour. Despite using it to vacuum my apartment after already having used my own vacuum, it filled up almost instantly with stuff my personal vacuum left in the carpet. My current vacuum is a V15, and I like it a lot. It was expensive (and a gift), but it's very effective, has a lot of attachments to make it easier to clean upholstery/the carpet/a computer/drawers/hardwood/the window frames/whatever, comes with a wall mount that the cable connects to so you can just put it in the mount and it charges. The one issue I had seems to be a relatively well-understood issue with the electronics, which resulted in me having to spend another $100+ on a new housing - the electronics + motor + LCD screen + etc., basically the whole 'vacuum' part of the vacuum. Given how well it's treated my so far, though, I'm not too miffed. Our last vacuum (which we still have) was a Miele, and while it was also fantastic it was far more of a pain in the ass since it's a plug-in with a bag vs. a cordless canister. The quality is similar, I think the Dyson is a bit better, but I use it exclusively because it's far easier to go get it, vacuum up a spill, and put it back. I know that's more of a comparison between canister and bag vaccums, but the fact that they're around as effective despite the dyson being a canister is I think a point in its favor. Whether all of their stuff is as good, or only the more expensive stuff, I can't say.

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!

"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.

  I was a little excited at the idea of a toothbrush that would suck my teeth and gums, and then was very disappointed when it turned out to be a camera in my mouth.
klustregrif 17d ago
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.
- mattlondon 17d ago
  My dentist recommended the dental picks (which can be used multiple times) instead of tape/string. I find it a lot easier than trying to fit my hands on my mouth (especially the longer L-shaped picks)
  - senectus1 17d ago
    i find the inconsistent advice from "Dentists" very discouraging. just like midwives they all seem to have their own opinions that dont equate to scientifically researched advice, yet are presented in a way that if you;re not paying attention will be taken as such.
    - jhanschoo 17d ago
      It's also the case that different people have different mouths and habits and there is no one-size-fits-all solution, and the best option might be to try a variety of options and see what sticks for you.
Topfi 17d ago
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%.
- littlexsparkee 17d ago
  I used both and I notice the water flosser removes small pieces my floss didn't (sometimes it's too thin to pick up everything, even if you get the expanding kind). The worst is popcorn / chili flakes. At one point, I had some 5mm pockets and was recommended for surgery - with the water flosser and molecular iodine rinse I was able to avoid it altogether.

  There isn't great evidence to suggest that electric toothbrushes are much better at removing plaque than manual. E.g. this metaanalysis [1] found basically no difference. There are also studies that show that electric is better, like this meta-analysis that found a small effect [2] and this Cochrane review. [3] What I generally read in articles is that the single biggest thing that makes a difference is brushing for the full 2 minutes, and electric toothbrushes can help with that by having a built-in timer. 1. https://pubmed.ncbi.nlm.nih.gov/38348549/ https://pubmed.ncbi.nlm.nih.gov/38348549/ 2. https://pubmed.ncbi.nlm.nih.gov/34877772/ https://pubmed.ncbi.nlm.nih.gov/34877772/ 3. https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD002281.pub3/pdf/CDSR/CD002281/CD002281_abstract.pdf?utm_source=chatgpt.com https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD...

    I haven't yet tried the units from Amazon where you connect the Waterpik to the faucet, but perhaps they could be good -- for me the problem has always been how small the water container was.
- darksim905 17d ago
  an ultrasonic scaler is far better at removing plaque and build up than a waterpik. I find that a waterpik is only really best at areas where there is high crowding, or hard to reach areas behind molars, etc.
  - spidersouris 17d ago
    But dental scalers don't offer the advantages water flossers do for gums, do they? Plus, from whet I've read online, it seems that these devices need to be used after brushing, as opposed to water flossers which are used before brushing. And for dislodging food (especially with braces), water flossers remain the best tool.

Problem is there are no good cameras for the OnlyFans subscribers that have a teeth and gums fetish. 4K is the solution that takes them deep inside. /s

  I wonder what stack they're using to stream live video from the toothbrush to the phone. I wonder whether the camera can still be activated when the toothbrush is sitting on your bathroom sink countertop, pointed at your shower.

Never been less satisfied than having bought a Dyson vacuum. Cheap plastic construction

dml2135 17d ago
I had the plastic trigger fail on mine. Took the whole thing apart and replaced it with a metal trigger from AliExpress. It’s been going strong since. I’m not usually a conspiracy theorist, but if I was a product engineer looking for a way to make my well-engineered product fail just after the warranty period was up, that trigger failure looked like a pretty good candidate. There was a specific piece of the plastic that looked like it was ostensibly there as a structural reinforcement, but it was clearly too short, and the trigger had cracked just past it. ifixit guide for the curious: https://www.ifixit.com/Guide/Dyson+V11+Trigger+Replacement/147481 https://www.ifixit.com/Guide/Dyson+V11+Trigger+Replacement/1...

I had a dc03 animal for over 10 years, kept replacing bits.. this year replaced it with the modern equivalent as I didn't want a battery powered one. The new one just feels sort of flimsy in all sorts of ways, definite buyers remorse, the old one just felt indestructible + really powerful, this seems a bit crap.
rebeccajae 17d ago
I was given a V6 and I bought an adapter that lets me use my dewalt batteries with the vacuum. Kind of a cool party trick but I think they were like $600 new which is bonkers.
IshKebab 17d ago
Rubbish. All vacuums are plastic and Dysons actually use quite high quality plastic. When I worked there they were always really worried about Shark, because apparently they have better pick-up benchmark scores. I bought one recently. Absolute trash. It has some bullshit automatic power control thing that is on by default but just varies the power completely randomly. So every time you turn it on it takes about 5 seconds - on, low power, high power finally. Vs the Dyson where you just pull a trigger. Never again. Dysons are the best. Very expensive, but just buy the older models or refurbished. Also don't bother with the hair drier or the cold fans. Not worth the price. The hot fans might be I guess.

The water jet ruined my teeth. I would not advise anyone to use them.

> 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. Not in any way knowledgeable on Dental Hygiene, so take this for layman's advice from someone who has used a water flosser for half a decade to positive effect: To anyone reading, please read the instructions in terms of proper usage, how to place it, etc., don't go full blast in the first few weeks and absolutely clean it according to the instructions. At least always empty the water fully and dry it out with the reservoir opened. Not saying this is what caused your negative experience, mind you. Again, Dental is not my field (Dentists, feel free to correct me if anything I wrote is wrong), but from my understanding and reading (I did read some papers when deciding to buy my first, cause of course I do my purchasing decisions on PubMed), some peoples gums seem to be simply more sensitive [0] to water flossers, even with proper device maintenance. In the end, always clear with your dentist. [0] https://pmc.ncbi.nlm.nih.gov/articles/PMC11180943 https://pmc.ncbi.nlm.nih.gov/articles/PMC11180943

Bit off topic, but if you suffer from canker sores, SLS (sodium lauryl sulfate) is a known contributor to that in some people (me included). It's a bit hard to find toothpastes without it that aren't also fluoride free, but they exist.

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-midjourney 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=/thread/250886390 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".

al_borland 17d ago
$500 + $15/replacement head. That’s assuming you can even get them. Right now they are out of stock, and my bet is these will never be something you can just pick up at the grocery store. Any time I’ve bought something with frequently out of stock consumables, it’s been a mistake. It quickly falls out of favor.

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.

Dyson was good for some products in the 1990s. Their quality has fallen in recent years, and other companies have caught up with them in other regards such as vacuum cleaners.
danudey 17d ago
I borrowed a dyson vacuum once from a neighbour. Despite using it to vacuum my apartment after already having used my own vacuum, it filled up almost instantly with stuff my personal vacuum left in the carpet. My current vacuum is a V15, and I like it a lot. It was expensive (and a gift), but it's very effective, has a lot of attachments to make it easier to clean upholstery/the carpet/a computer/drawers/hardwood/the window frames/whatever, comes with a wall mount that the cable connects to so you can just put it in the mount and it charges. The one issue I had seems to be a relatively well-understood issue with the electronics, which resulted in me having to spend another $100+ on a new housing - the electronics + motor + LCD screen + etc., basically the whole 'vacuum' part of the vacuum. Given how well it's treated my so far, though, I'm not too miffed. Our last vacuum (which we still have) was a Miele, and while it was also fantastic it was far more of a pain in the ass since it's a plug-in with a bag vs. a cordless canister. The quality is similar, I think the Dyson is a bit better, but I use it exclusively because it's far easier to go get it, vacuum up a spill, and put it back. I know that's more of a comparison between canister and bag vaccums, but the fact that they're around as effective despite the dyson being a canister is I think a point in its favor. Whether all of their stuff is as good, or only the more expensive stuff, I can't say.

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!

"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.

I was a little excited at the idea of a toothbrush that would suck my teeth and gums, and then was very disappointed when it turned out to be a camera in my mouth.

klustregrif 17d ago

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.

mattlondon 17d ago

    It's also the case that different people have different mouths and habits and there is no one-size-fits-all solution, and the best option might be to try a variety of options and see what sticks for you.

Topfi 17d ago

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%.

littlexsparkee 17d ago
I used both and I notice the water flosser removes small pieces my floss didn't (sometimes it's too thin to pick up everything, even if you get the expanding kind). The worst is popcorn / chili flakes. At one point, I had some 5mm pockets and was recommended for surgery - with the water flosser and molecular iodine rinse I was able to avoid it altogether.

There isn't great evidence to suggest that electric toothbrushes are much better at removing plaque than manual. E.g. this metaanalysis [1] found basically no difference. There are also studies that show that electric is better, like this meta-analysis that found a small effect [2] and this Cochrane review. [3] What I generally read in articles is that the single biggest thing that makes a difference is brushing for the full 2 minutes, and electric toothbrushes can help with that by having a built-in timer. 1. https://pubmed.ncbi.nlm.nih.gov/38348549/ https://pubmed.ncbi.nlm.nih.gov/38348549/ 2. https://pubmed.ncbi.nlm.nih.gov/34877772/ https://pubmed.ncbi.nlm.nih.gov/34877772/ 3. https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD002281.pub3/pdf/CDSR/CD002281/CD002281_abstract.pdf?utm_source=chatgpt.com https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD...
