- abdullahkhalids 1y agoThe wikipedia article [1] suggests that there is no strong evidence for flossing being a good thing. However, that might just be because experts have not updated the article.

- derbOac 1y agoMeta-analysis suggests flossing doesn't affect tooth decay. But it does seem to prevent gum disease.
- Defletter 1y agotbf, it does require a technique otherwise you risk just pushing plaque underneath your gums
- EvanAnderson 1y agoSame feeling here. Dental seems particularly fraught (though maybe I just pay more attention to it out of interest). I know the cycle time between press releases/hype and actual application can be the better part of a decade, so I assume that's coloring my perception too. re: dental in particular - It seems like enamel regeneration and stem-cell-based tooth replacement have both been in the news year-after-year without applications actually coming to market.
- matthewfcarlson 1y agoEveryone knows that teeth are luxury bones in the US. The market just isn't there for fancy treatments. The ultra-wealthy just get their teeth replaced with perfect veneers anyway.
- iamacyborg 1y ago> The ultra-wealthy just get their teeth replaced with perfect veneers anyway. Na, that’s the working class turkey teeth crowd.
- thaumasiotes 1y ago> stem-cell-based tooth replacement Really? This sounds more like someone's plan to get grants to research stem cells than someone's plan to repair (or replace) teeth. We already have a natural ability to grow new teeth that replace existing ones. Everybody does it... once. Where's the research into getting it to happen again?
- gus_massa 1y agoTheet formation is a very early procces, even before the baby is born. > Primary (baby) teeth start to form between the sixth and eighth week of prenatal development, and permanent teeth begin to form in the twentieth week. So it's probably too late for you.
- cluckindan 1y ago
- elicash 1y agoWhile I 100% agree with what you wrote, I'd just add that it does seem in my own dental visits over my lifetime that there have been real advancements, too. But yes, I agree, hard for non-expert to parse.
- 0_____0 1y agoSeeing SLA 3D printers at my dentist's office was pretty cool. Apparently they use them for a variety of fixturing and jigs, and have a workflow that includes a handheld scanning unit that SLAMs to generate a solid model of the patient's teeth.
- limaoscarjuliet 1y agoI have 4 crowns, 2 done using moulds, 2 using the 3d scanner. Same doc, same office. The moulded ones were ok with some adjustments, but the 3d scanned ones were perfect since day 1. I'm happy with the progress in dentistry.
- throwaway2037 1y ago> there have been real advancements Can you share some specifics?
- socalgal2 1y agoI'm surprised how many low-hanging fruit issues are still not solved. So many dentists use cold or tap water for their rinse sprayer despite the fact that many people have temperature sensitivity issues with their teeth. Having lukewarm water would be trivial but I've yet to go to an American dentist that does it.
- CGMthrowaway 1y agoA similar approach was reported in 2019,[1] but that produced thinner coatings, and the recovery of the architecture of inner layers of enamel was only partial. [1]https://www.science.org/doi/10.1126/sciadv.aaw9569 https://www.science.org/doi/10.1126/sciadv.aaw9569
- paulpauper 1y agoyup here is one from 2007 https://www.technologyreview.com/2007/02/22/272845/regrowing-teeth/ https://www.technologyreview.com/2007/02/22/272845/regrowing... As it turns out, this is really hard to do. There are a lot required of teeth: they have to be extremely durable to resist repeated strain of chewing ,stay in the gums, not be rejected by body, etc. It's little surprise progress has been so slow.
- PaulKeeble 1y agoJust 7% of studies that do a preliminary study on humans actually get through phase 3 and get approved for use. This is before even the preliminary point, its a tooth (or even a tooth analogue) in a petri dish. No idea if the material will be safe in a human mouth yet. There is a lot of hyping of results in medicine papers in general but its not really their fault. The entire academic world is being forced to publish or die as governments look to measure results from the science they instead get what is measured and everyone has to embellish the importance of what they found and always find positive results.
- palmotea 1y ago> The entire academic world is being forced to publish or die as governments look to measure results from the science they instead get what is measured and everyone has to embellish the importance of what they found and always find positive results. It sounds like they're running it like a business.
- dlcarrier 1y agoOver time, any large business trends to increase in bloat and inefficiency, and focusing on inappropriate metrics is a big part of that. This eventually leads to competitors taking over and those business failing, which usually results in people losing their jobs. When governments get equally incapable, and competitors take over, it tends to be a lot more violent.
- palmotea 1y ago> This eventually leads to competitors taking over and those business failing It's important to note that "eventually" usually takes so long that it might as well be forever.
- autoexec 1y ago> This eventually leads to competitors taking over and those business failing If only that fairytale were true. In the real world bloated inefficient companies bribe government, install themselves into government agencies directly (regulatory capture), and hire lobbyists to write laws which protect them from pesky upstarts through unchecked anti-competitive practices and anti-consumer regulation allowing them to stay wealthy and in power forever while killing off innovation and progress.

- throwaway2037 1y agoWhat about "Sensodyne Pronamel"? There is usually someone in the comments raving about its effects.
- robinson7d 1y agoI think usually they rave about Novamin, which, at least in Canada, isn’t in the Pronamel line IIRC but in other Sensodyne branded toothpastes. _EDIT: “repair and protect”_
- opello 1y agoThis was a good comment thread on which brands or markets had what with regard to hydroxyapatite: https://news.ycombinator.com/item?id=36564190 https://news.ycombinator.com/item?id=36564190
- mikaraento 1y agoI can be that someone this time. The ”repair and protect” version has helped my low-level toothache.
- archon810 1y agoI've actually been occasionally using Enamelon because it was recommended by my dentist for sensitivity and I think it actually works. I'm going to try Boka as recommended above though, it seems like a more updated and modern solution.
- kjkjadksj 1y agoIt is probably tough getting investment because this is ultimately cosmetic and not something covered by most dental insurance. Existing repair is probably good enough and I’d expect cheaper too.
- caycep 1y agoI would say, maybe look at medical studies from the opposite end, epidemiological studies look at factors that reduce mortality/morbidity. Granted, it's less flashy, basically vaccines, alcohol/tobacco reduction, increase in active lifestyle, statins/ace inhibitors, monoclonals/oncology fanciness. although someone who actually is an MPH can probably correct me. on the neuroscience side, off the top of my head, the most impactful things have been better anticoagulants and preventive care for stroke, monoclonal abs for autoimmune diseases like MS/myasthenia, , certain stereotactic brain surgeries, and such. But considering what ails most people, the overall population effect probably is minuscule compared to say better crash safety in automobiles.

- hattmall 1y agoART with HVGIC has basically solved dental caries since the 80s. But you aren't likely to get it in the US or most western nations because there is a massive industry around drilling and filling with resins and then solving the multitude of problems that such a destructive process creates.

- thefounder 1y ago>> I feel like I've been reading this exact same article for the last 15 years.. You must be new
- randomtoast 1y agoA better approach is to monitor FDA updates. When an FDA trial shows positive results for a new treatment and approval for public use appears imminent, that would qualify as news in that regard.

- basch 1y agoYou can buy the supplies and make nano silver flouride now, relatively cheaply compared to dental work. If you have a non corporate dentist, you could even ask them to apply it. The basic mechanism has been used on teeth forever, and adding the nano particles prevents the chemical from permanently staining your teeth black or blue (which is why it hasnt ever been more popular to begin with.) https://fourthievesvinegar.org/tooth-seal/ https://fourthievesvinegar.org/tooth-seal/

- xnzakg 1y ago
- ptrl600 1y agoWell until this stuff comes out I'll keep using smuggled FDA-unapproved Novamin toothpaste. Atonement for my neglect
- ribosometronome 1y agoSensodyne?
- Waterluvian 1y agoI just learned about this 5 mins ago and did some basic research. Here's what I found: - Sensodyne Repair and Protect contains 'NovaMin' (possibly only in some markets; check the ingredients!) - NovaMin is the brand name for calcium sodium phosphosilicate - It reacts with saliva to form a physical layer of hydroxyapatite on your teeth - This layer blocks the tubules that trigger pain from temperature and such - It also supports remineralization (how exactly?)
- paulgerhardt 1y agoBecause it keeps coming up there is an anti-Novamin crowd that says it’s useless and Biomin is the true re-enamelizer.
- Waterluvian 1y agoInteresting. A very rudimentary web search begins suggesting that Biomin is the more suspicious of the two. It has a very weird Internet footprint of being this somewhat obscure-looking expensive "Health" product. I really can't find any recognizable sources on the product name. Maybe the obscurity is part of the exotic allure for some?
- kelnos 1y agoI used BioMin F for about a year, and I think it did something, but I'm not sure I'm qualified to evaluate its effectiveness. Unfortunately it isn't actually available where I live (US), and I had to buy it from Canada... from a shop that hasn't had stock for more than a year now. I've tried ordering from other countries, but haven't found anyone else who will ship to the US. I've tried the "BioMin Restore" toothpaste that is available in the US, and I don't feel like it's doing much of anything, but... again, not sure I'm qualified to evaluate.
- Waterluvian 1y agoIf anyone's a dentist or is close to one, I'd love to know something I haven't found a satisfactory answer for online: if the vast majority of cavities were "magically" cured over the next few years, what impact would that have on the finances of your practice? I'm not suggesting there's a conscious conspiracy or anything malicious. But I observe that incentives are weirdly aligned. I wonder what this kind of thing would do to a very large industry if all of a sudden some percentage of business disappeared. Is it a large percentage? Would they pivot to more preventative medicine? Would patients adopt a longer duration between checkups?
- umvi 1y agoI think there would just be fewer dentists. It's like asking what would happen to the finances of weight loss clinics if magically Americans weren't as obese.
- elicash 1y agoI will say my dentists always try to convince me to floss more often, regardless of any economic benefit they might have for me to disregard my teeth. I also would imagine cleanings aren't where the big money is in the profession, but like you would be interested to hear from actual dentists.
- doubled112 1y agoNot a dentist but I definitely couldn't see it going away. Also curious to hear a more knowledgeable opinion. There will always be accidents and need of non-cavity repairs. As a kid I broke a healthy tooth eating Doritos. It didn't make sense to my dentist either. I've broken a less healthy (but repaired) tooth on a candy coated peanut, and one a Twizzler Nib. I grind my teeth, so everything is being worn and torn at a higher rate. The mouth guard won't generate itself. Hate to say it, but if I thought my teeth would stick around longer, I'd probably be more likely to seek cosmetic fixes. I'm apparently really hard on them or something.
- riderist 1y agoI’m a dentist. If cavities vanished tomorrow, it would definitely change things, but not as much as you might guess. Cavities and crowns make up a decent slice of what most general practices do, but there’s still gum disease, cracked teeth, teeth wear, implants, bite issues, cosmetic work, and so on. A lot of what keeps people coming in isn’t just sugar, although from the outside I understand why it might look like sugar is the whole game. Financially, there’d be a short-term hit for offices that rely heavily on fillings, but the field would adjust. Most of us would focus more on prevention, maintenance, and elective care. Dentistry has already been slowly shifting that direction for years with better materials, scanners, and aligners. So if everyone suddenly stopped getting cavities, I’d still have plenty to do. It would just look a little different.
- byearthithatius 1y agoPoorly designed studies, materials proposed without insight into ramifications and manufacturing, and P-Hacking has ruined the publics trust in science. I blatantly just ignore any headline like this now. Can't trust science anymore.... sad. How many new "cancer cures" have been posted to Reddit and HN over the last decade that never came to fruition. Not to say doing the science and studying to find new approaches is not beneficial. I just think we need to reconsider how we communicate new research. Its like how CEOs hype up AI products at this point. "This will change everything ..... potentially maybe in twenty years (omitted)"
- kazinator 1y agoScrew enamel; man-made materials are better. If you ever get into any serious money, forget cars or houses: have your teeth ripped out and replaced with artificial ones.
- inglor_cz 1y agoAn artificial crown may be better, but not the roots. Natural teeth are fixed in the jaw in a very ingenious way that is durable and somewhat flexible at the same time. Not so with implants; the metal fuses with the bone in a hard way and transmits all the shocks fully into the jaw.
- sssilver 1y agoWhat are the disadvantages of having all the shocks go fully into the jaw?
- kelnos 1y agoDiscomfort and pain, I would assume. I wouldn't be surprised if this can, over time, also cause damage to your jaw, and put extra stress on your jaw muscles.
- inglor_cz 1y agoDepending on the location, state of the bone and other parameters, anything from mild discomfort to catastrophic failure of the implant and a jaw fracture. I have four implants, two in my lower jaw, two in my upper jaw. My lower jaw is basically stone, an extremely hard bone even by usual lower jaw standards; the dentists (plural, as one was unable to finish the job) drilling into it destroyed a few drilling bits doing so. I have never had any problems with the lower jaw implants. That bone can take almost anything in stride. My upper jaw, on the other hand ... very delicate, just enough bone left for the implants to work, and I learnt to be careful about biting into anything harder with them.
- loloquwowndueo 1y agoIt’s like having a car with no shock absorbers.
- Razengan 1y agoYou know it's weird how we don't have a general "healing" gel yet..
- blobbers 1y agoPretty sure I get re-targeted by ads for various versions of this for weeks on end after I do a single google search for a new toothpaste. Usually the safety profiles of those companies are very very very bad, but probably reference very good research.
- t1234s 1y agoThere is the potential of ability of people to regrow teeth https://www.popularmechanics.com/science/health/a66012157/human-new-tooth- https://www.popularmechanics.com/science/health/a66012157/hu... regrowth-trials-japan/ This would highly disrupt the dental-industrial-complex

- kawfey 1y agoI just went down a rabbit hole researching a toothpaste that's giving me constant ads. I went looking for reviews and ended up posting a comment on /r/PeriodontalDisease - https://old.reddit.com/r/PeriodontalDisease/comments/1bcna04/livfresh_toothpaste/nnbayfb/ https://old.reddit.com/r/PeriodontalDisease/comments/1bcna04... TL;DR: EDTA is the magic ingredient that will annihilate the disease-causing biofilm on your teeth & gums, especially when you fund your own studies and spend the rest of your money made from your overpriced toothpaste gel on marketing. Just brush and floss 2x a day, and chew gum if you like to.
- HumblyTossed 1y agoHow many of these have we heard about over the years and yet … none ever come to market.
- maxglute 1y agoAs someone with low maintenance teeth how far has dental tech procedures improved in last 30 years? Feels dental hygienist are all using tools that haven't changed in decades.
- chasingthewind 1y agoMy dental practice has only one significant improvement that I’ve noticed in the last 30 years, which is to use a sonic scaler to remove plaque instead of manual scraping with an implement. Somebody in the field would certainly be able to provide a better and more informative answer.
- krageon 1y agoTo a normal human, not at all
- mikelabatt 1y agoAny thoughts on how this might be different from existing products like GC Tooth Mousse (CPP-ACP-based, recommended by our children's dentist)? A paper from 2011 on the topic: https://pmc.ncbi.nlm.nih.gov/articles/PMC9374843/ https://pmc.ncbi.nlm.nih.gov/articles/PMC9374843/
- halosghost 1y agoHey @dang (I know it doesn't work, but isn't it fun to use your imagination?), can we get this press release replaced by a link to the actual paper [0]? This one is even open-access! All the best, -HG [0] https://www.nature.com/articles/s41467-025-64982-y https://www.nature.com/articles/s41467-025-64982-y
- RivieraKid 1y agoWhy? The press release is much more useful for the vast majority of HN readers in my opinion. The paper is something you read if you want to know more so the right place for it is the comments. In general, not referring to this specific case, scientific papers are often written for people with specialized background and are hard to understand for people without that background, even if they're otherwise smart and educated.
- halosghost 1y agoJust to say, I actually disagree entirely. I do not believe press releases are, almost ever, valuable. Papers are just a format (with some writing style conventions that tend to follow the given field-of-study); they may be intimidating for many, but the hacker spirit and ethos is to dive in and tackle it, and that will pay far more dividends for everyone reading it than to consume more advertising. :) All the best, -HG
- wildzzz 1y agoUnless you are actually familiar with odontology or work in the field, the paper carries little significance for the average layperson (most of us on HN).
- _zagj 1y ago> When applied, the gel creates a thin and robust layer that impregnates teeth, filling holes and cracks in them. Having an option other than crowning to treat cracks would be a game-changer, especially since the AAE not long ago put out a policy paper recommending that all teeth with cracks (even asymptomatic) receive crown coverage, which is both costly and presents a risk of inducing irreversible pulpitis and subsequent necrosis in the tooth (due to the heat and mechanical trauma of the crown prep.).
- sharts 1y agoSounds like...Novamin? That good stuff we used to have but is now not legal in the US but available to other countries. Hmm.
- emmelaich 1y agoInteresting. We have a Novamin-containg toothpaste in Australia, but you have to hunt it down.

- andrewstuart 1y agoI ask my dentist about this cause it keeps appearing. He’s a pretty modern dentist I think. He has no idea about it.
- cubefox 1y agoCoincidentally, there recently was a very similar story from another UK university, where they used a substance found in hair to make a new "tooth repair" toothpaste: https://news.ycombinator.com/item?id=44922571 https://news.ycombinator.com/item?id=44922571
- willgax 1y agoone of my front tooth was chipped years ago while playing around and some days ago i was feeling sensitive in that tooth i take very good care of my teeth, when i visited dentist he said this tooth will die sooner or later because of trauma it endured the nerves will slowly die and we eventually have to do root canal. i was very disappointed to know that there is nothing i can do to keep that tooth alive
- bogantech 1y agoGet a second opinion
- willgax 1y agowell most of research i did online and the numerous videos i watched about when root canal is necessary tell this as cases that when tooth endured trauma it will slowly die it may take upto 10 years in this case nothing can be done to save tooth there maybe some experimental approach that i dont know of that may save or heal tooth do you know any?
- mywittyname 1y agoIf it helps, I bashed my face into a step when I was like 10, cracking one front tooth and traumatizing the other. Neither tooth has needed a root canal. I get the chipped one repaired every ~10 years or so. The other is discolored.
- BriggyDwiggs42 1y agoWhen i was a kid another kid stood up into my jaw, slamming my top and bottom teeth together in a weird way. My top two front teeth were basically split in half. They reconstructed those broken-off portions with porcelain or whatever and they’ve never needed to do anything else.

- vibrio 1y agoAny specific reason? Are you concerned about Purity of Essence?
- bruce343434 1y agoI have replaced my sensodyne with mirasensitive hap+. It is more expensive, even more so than sensodyne. However it has helped incredibly with my exposed roots which used to be very sensitive. Now they are less sensitive than they used to be with sensodyne. I can swish cold water and eat sour foods again. My current routine is roughly brush_teeth(toothpaste={mirasensitive, random_cheap_toothpaste}[day%2]) as you don't need to apply HAP every single day. I find that I still have to be careful eating apples and lemons straight up. To protect myself I thoroughly swish and rinse water a few times shortly after consuming these fruits. If I don't do that, my teeth get extremely sensitive and it takes a few days for the hap to repair it again.
- tomdekan 1y agoI've been enjoying using this over the past 3 weeks. This is nano-hydroxyapatite, meant to be more effective than hydroxyapatite alone. https://www.boka.com/ https://www.boka.com/ (P.S I'm not affiliated with boka)
- archon810 1y agoThank you for the mention of Boka. This sent me down a rabbit hole of research, both the positives compared to other toothpaste, like not containing SLS, parabens, or titanium dioxide, but also the findings of trace amounts of lead, arsenic, and mercury in it. The trace amounts are much lower than the standards considered okay by the FDA and the European regulators, but not EWG, which doesn't accept pretty much any trace amounts. I decided to try it after all.
- swiftcoder 1y agoIs this going to be another Theodent? For the uninitiated, Theodent is a $100/tube toothpaste made with the chocolate extract theobromine, instead of fluoride, based on a similar paper quite a while back.
- seethishat 1y agoDoesn't xylitol gum do the same thing? Re-mineralize teeth?
- 2ekjadyfe 1y ago[dead]
- tomdekan 1y agoXylitol reduces cavity‑causing bacteria and raises salivary flow, which can increase calcium and phosphate availability. That environment supports natural remineralisation and boosts the effect of fluoride or hydroxyapatite products, but xylitol itself doesn’t deposit minerals into enamel. For actual mineral replacement, look to fluoride toothpaste/varnish, casein phosphopeptide‑amorphous calcium phosphate (CPP‑ACP), or nano‑hydroxyapatite formulations; xylitol gum is a useful adjunct.
- amai 1y agoMy teeth are so much better since I stopped drinking alcohol. I have no clue why that is, but drinking alcoholic beverages with sugar (e.g. cocktails) was especially bad. Since I stopped drinking alcohol I don't have any issues with my teeth anymore.
