- NAR8789 3y agoPrevious article had to sniff the NFC password when the handle connected to the head. New article has a convenient form to generate password. How did they reverse the brush head password algorithm? https://youtu.be/EPytrn8i8sc https://youtu.be/EPytrn8i8sc "Hacking the Phillips Sonicare NFC Password" (buried three links deep)
- dylan604 3y agoIs using a screen capture software expensive or difficult to do? In 2023, why would someone not use one instead of hand holding a phone to record so that every time they look away, the phone bounces and makes whatever they are showing on the screen impossible to read?
- vinnymac 3y agoMost people I personally know would reach for a phone to record a video. They are simply more familiar with it, and while some may be aware screen capture exists, it usually requires some setup, and knowledge of a macro.
- Timothee 3y agoIt’s a bit frustrating for how much time is spent showing a screen. However, making the same video with screen capture would require a good amount of editing to also show the toothbrush. Here everything seems to be in one take. I don’t blame him; as easy as it is now, editing is still time consuming.
- ndsipa_pomu 3y agoI think these consumer-hostile devices and brands need to be named and shamed and ideally, some kind of consumer movement to boycott them. Unfortunately, too many people either don't care or believe that they want that functionality.
- rplnt 3y agoIt's not really hostile in this particular case. It beeps a few times when the status changes and then just displays led in amber instead of green. It is kinda sad how much effort went into this "functionality", how much it increases the cost of the device, but selling replacement heads is their primary business. Maybe the brushes would be more expensive without the NFC reader and timers.

- ndsipa_pomu 3y agoJust changing the colour of an LED seems okay to me. I'm thinking more of the HP school of business where the toothbrush would stop working until the correct proprietary brush was replaced.
- nolongerthere 3y agoYea I have this toothbrush too, I also noticed the weird IC on the bottom of the brush head when I first bought it, I nearly correctly surmised what it did, was a little upset at the prospect of being forced to buy a new head when Phillips decided it was time, but it turns out it doesn’t really do anything, it buzzes a few times at the end of brushing when it thinks it’s time. And the LED changes color… who cares… The recommendation generally is to replace your tooth brush semi-annually, which this basically reminds you to do.
- maxerickson 3y agoA lot of recommendations are every 3 to 4 months.
- constantly 3y ago“You might have noticed the color of the brush head changing throughout of this post. This is because I had to run out and buy a new one after getting locked out of the first one.” The concept of getting locked out of one’s toothbrush head is so absurd it might as well be dystopian.
- beebeepka 3y agoWhat's there to be locked out of? I've this brown diode blinking for half an year. Are they disabling the vibrator?
- oasisaimlessly 3y ago> [We] can see that the tag is configured to permanently disable all write access after three wrong password attempts. (Which I promptly exceeded when playing around) This means that not even the toothbrush handle itself can write to this head again.
- tgsovlerkhgsel 3y agoWhat happens in that case? Does the toothbrush misbehave/consider the brush beyond its lifespan, or is it a convenient way to disable this feature?
- pests 3y agoJust disable the feature the way the manufacture instructs instead of this random hacking? Why pull out all the engineering tools when the step by step is in the manual?
- lights0123 3y agoIt didn't mention that the toothbrush failed to keep vibrating, just that the toothbrush head lost its function as a writable NFC tag.

- PerryUlyssesCox 3y agoThe orange light on the toothbrush comes on after three months to remind you to change it - it's only slightly annoying but this worked perfectly to reset it.
- NegativeLatency 3y agoIt’s better for your mouth/teeth to change the brush, it’s not really visible but there’s a difference in how effective an old brush is at plaque removal compared to a new one.
- kanapala 3y agoIt doesn’t work for me :( 04:1C:C9:AA:BE:12:91 23041911K
- PerryUlyssesCox 3y agoYou need to include the space (230419 11K)
- kanapala 3y agoNice, thanks.
- sintezcs 3y agoHmm. The article says that after 360 minutes of use, it will tell you to replace. A regular tooth cleaning cycle is 2 minutes. So it’s 4 minutes for morning plus evening. 360/4=90 days..usually I replace my toothbrush head every 2-3 months, and I think this is what dentists also recommend. Why would I ever want to reset this counter?
- I_Am_Nous 3y agoHow long before you are ingesting significant amounts of microplastics from the bristles dissolving?
- resoluteteeth 3y agoIf that's an issue I suppose you could brush your teeth, rinse your mouth, and then use a fluoride mouthwash like act
- contingencies 3y agoIIRC mouthwash has been debunked as a post-brush routine and is better deployed post sugar consumption in lieu of immediate brushing. https://nypost.com/2021/07/13/dentist-warns-to-never-use-mouthwash-after-brushing-teeth/ https://nypost.com/2021/07/13/dentist-warns-to-never-use-mou... https://askthedentist.com/mouthwash-risks-and-alternatives/ https://askthedentist.com/mouthwash-risks-and-alternatives/ https://www.rd.com/article/health-danger-mouthwash/ https://www.rd.com/article/health-danger-mouthwash/
- hnarn 3y agoCategorical statements like these are infuriating. What has been “debunked” is that you should not use mouth wash that has a lower fluoride content than the toothpaste you used right before, or mouth wash that is anti-bacterial. Not all mouthwashes and toothpastes are equal, therefore this categorical statement is wrong, and nothing has been “debunked”. The mouth wash I use is the one recommended by my dentist, it is not anti bacterial and it has 0.2% fluoride. The last article you posted simply lies: > Mouthwash contains an antiseptic compound called chlorhexidine. No it doesn’t. Not all mouthwash contains that. I recognize it though, because it’s what I use as an antiseptic alcohol to clean bruises.
- aaronbrethorst 3y agoMe, dumb: I change my Sonicare toothbrush head whenever it tells me to. I haven’t had a cavity in 8 years. You, a clever toothbrush-hacking genius: haha, the head is new again!
- Infinitesimus 3y agoCavities can be the result of many things, including genetics
- 0x073 3y agoOld toothbrushes are bad for gum. This is not only a cavities problem.
- jbverschoor 3y agoI'm more interested in getting the mouse cursor on my machine
- secondcoming 3y agoSonicare is the best toothbrush yet normal shops only seem to stock oralb heads. You can get non-smart sonicare heads too.
- bigstrat2003 3y agoI do think shops should stock both, but personally I can't stand Sonicare. I tried using my wife's toothbrush (I was a manual brushing guy at the time and wanted to check it out), and it actually hurt to use because the vibration was so intense. I figured that electric toothbrushes weren't for me and just went back to manual brushing, until my wife got me a cheap Oral-B to see if I liked that more. It's been really nice actually, and I've been planning to get a nicer Oral-B model. But yeah, I would far rather manually brush my teeth than use a Sonicare with how uncomfortable they are.
- secondcoming 3y agoSonicare has 4 or 5 different brushing modes. Newer models even alert you if you’re pressing too hard. If all of the modes hurt you must have really sensitive teeth!
- ranting-moth 3y agoRelated, has anyone gotten a solution to the Oral-B/Braun toothbrush bug where it refuses to start after being fully charged? You pop it back in the charger and immediately it'll have full charge and start again! I've been caught out on this more than once and I'm not the only one. I make sure it's fully charged and pop it in my travel bag. Then when I'm 2000 miles from my charger I find out it refuses to start!
- romseb 3y agoAfter spending way too much time looking for the "perfect" toothbrush, I eventually ended up with a twig from a tree [1]. I do not look back after dealing with non-replaceable batteries, expensive heads and generating way too much electronic waste than necessary [2]. My teeth have been perfectly clean and healthy after years of use. I do not need toothpaste and am much more inclined to clean my teeth in between meals because I do not need to stay in the bathroom for it anymore. [1] https://en.wikipedia.org/wiki/Miswak https://en.wikipedia.org/wiki/Miswak [2] If everyone would switch to twigs, we could save thousands of tons of waste every single year. "The global electric toothbrush market size was USD 3.16 billion in 2022 and is projected to grow from USD 3.27 billion in 2023 to USD 4.37 billion in 2030"
- y-curious 3y agoThis[1] is exactly what I'm worried about with a miswak. No way you're hitting all of your tooth surfaces. [1] "Its bristles lie in the long axis of the stick, whereas those of a toothbrush are placed perpendicular to the handle. Thus, it is difficult to reach the lingual surfaces of the dentition with a miswak. Another disadvantage is related to the habitual use of miswak for a prolonged period... reported that chewing-stick users may excessively scrub the anterior teeth, which are located in the area of primary concern, while ignoring the posterior teeth.

- romseb 3y agoThe fresh stick is quite flexible, so you can reach all surfaces after a small learning curve, but I actually combine it with this handle: https://www.swak.de/was-ist-die-swak/swak-miswak-zahnbuerste/ https://www.swak.de/was-ist-die-swak/swak-miswak-zahnbuerste...
- kaliszad 3y agoI would strongly recommend to make an appointment with a respected dental hygienist instead as you obviously have many misconceptions about dental hygiene/ brushing teeth. (Source, my fiance is a well established dental hygienist with her own office in Prague, Czechia. I have consulted the following text with her, it is adapted from a previous comment of mine some weeks ago.) Perhaps it is good to have some basic knowledge how a cavity/ caries comes to be. From that you can derive whether you are on the right or wrong path to a reasonable dental hygiene. I would like to add that you can assume nobody is immune or has a resistance to caries. When we eat or drink the bacteria gets nutrients (any form of sugar) and builds up plaque and the bacteria create an acid. Because the plaque stays on our teeth above and even slightly bellow the gums (gingiva) and the bacteria likes to live there the effects are strongest where the plaque is. The bacteria and the resulting acid over time cause demineralisation, dissolves the calcium in the teeth. After some time this leads to decay which we describe as cavity/ caries. Also, the plaque can solidify into a build-up of tartar/ calculus which further provides a nice habitat for bacteria, causing gingivitis (inflamation of the gums - they become red and swollen) spreads the sulcus, basically splitting gums from the teeth over time which results in periodontitis, which is basically loss of the bone and other problems below the gums. Periodontitis can also exacerbate other illnesses such as diabetes, cardiovascular illnesses, possibly some allergies (active research). This can really only be fixed by a professional dentist or dental hygienist since removing the tartar, especially under the gums, is a precise and demanding. The procedure can be painful without local anesthetics. If you don't want all that do brush your teeth correctly each day. The 2 minutes number is myth again - do brush until the teeth are free from plaque. It is easier with a sonic/electric toothbrush, e.g. by Phillips or Oral B iO should be ok too. The brushing technique is very important, most people do this wrong. The brush should be at 45° to the sulcus (half of the bristles is on the gums the other on the tooth). Obviously also brush the top of the teeth. Each tooth basically has 5 surfaces, top and 4 sides. Don't forget to use correctly sized interdental brushes. Your dentist or dental hygienist should be able to help you find the correct sizes for specific spaces between teeth. (You will probably end up with TePe or Curaprox and probably more than one size.) You can use a solo brush too, which brushes exactly one tooth at a time. The bristles of the brush should be as soft as possible and removal of bigger amounts of plaque are done by spending more time instead of force/ pressure/ hardness/ abrasiveness. In addition to not replacement of interdental brushes, you can also use a super floss (the middle is made of a fluffy material) but learn a good technique so you don't hurt your gums, throw the thin waxed floss in the trash especially if you are not super handy/ careful as to not cut your gums. Also, the floss does not clean premolars and molars properly because of the shape of the teeth in interdental space (because of their concavity, imagine that the surface is basically made of two pillars). Do have a regular appointment with your dentist and dental hygienist. 2x a year should be enough with good hygiene. If you have more problems, the frequency of appointments will of course vary. They should definitely do at least intraoral x-rays each preventive appointment and a OrthoPantomoGraph in ~2 years.
- SV_BubbleTime 3y agoHmm… was not working me. Solved it. I get TAG CONNECTION LOST whenever I try and write with an iPhone 15 Pro. Philips sonic card brush, recent mfg. If you are having trouble with the last step of OTHER > ADV COMMAND, separate the two steps. Instead of pasting: 1B:C3:05:5C:30,A2:24:00:00:02:00 Try to separate them into separate steps. 1B:C3:05:5C:30 then A2:24:00:00:02:00 After that one worked, and one didn’t. The second one needed the command again, this time it worked as one.
