By halosghost 2025-11-062:091 reply Hey @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,

By RivieraKid 2025-11-0711:191 reply Why? 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.
By halosghost 2025-11-081:521 reply Just 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. :)

By wildzzz 2025-11-0817:00 Unless 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).
Is this a commercial product that has been approved by a regulator to make these claims? Amazing. Newsworthy.
Is this a press release from a university research group, as it appears to be (the site is down)? Then it's nearly meaningless.
You 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.)
By xnzakg 2025-11-0813:55 Also interested in this, but haven't tried it myself. Apparently NSF (Nano Silver Fluoride) is more commonly in non-western countries.
They have a video with some more info here: https://pt.fourthievesvinegar.org/w/9aa66b49-2ec5-497f-9f49-...
And apparently the use of NSF does have a bunch of research papers written about it: https://www.researchgate.net/profile/Amol-Patil-43/publicati...

By CGMthrowaway 2025-11-0520:01 By tootie 2025-11-061:07 I found other sites indicating it's entering trials soon to be on the market next year. That's still a bit speculative obviously, but it sounds more promising that just being a working theory.
Huh? If this was an article from a commercial entity selling a product we'd be calling it a marketing puff piece and asking for the science.
If it a commercial product marketed as "homeopathic" or various nonsense loopholes that the government has been bullied into leaving open, then sure.
But an actual medical product for sale to consumers that makes claims like "restores dental enamel" would have to present scientific evidence to the FDA that this claim is accurate.
By red-iron-pine 2025-11-0619:14 the FDA approves all sorts of nonsense, and plenty of commercial products slide through without
show us the study
By anonnon 2025-11-062:12 > 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.).
