I found the phrasing really difficult to read and understand, even though I got the pun, so you’re not alone in that.
So anyway, should we be calling this "hairpaste for teeth", or "toothpaste from hair"?
If keratin is the active ingredient, I would suspect the exact source doesn’t really matter.
We expect olive oil to be made from real olives, but not baby oil…
Linux Subsystem would be completely wrong, because it is a Subsystem of Windows not of Linux.
Y of X providing Z - Windows Subsystem for Linux.
Y providing X on Z - Linux Subsystem for Windows.
The former is "for [having]", the latter is "for [use on]".
MS has some confusing naming, this isn't one of them.
While W S for L is fine in the intended sense, it could just as well mean a subsystem on Linux that runs Windows (like Vine, I guess). Parallel examples might be Brake Pads for Chevys or Oven Cleaner for Microwaves.
As further examples of the weirdness of compound nouns in English, consider Atomic Scientist, which does not mean a scientist who is atomic, but rather an 'ist' (= person) who does atomic science. Likewise Nuclear Physicist, Artificial Intelligence Researcher (at least for now, since AI systems aren't researchers :)).
That's really great I hope to use this some day.
I use the latter. I do not know if it works, but I use it. I have never suffered from tooth pain before or after.
IIRC, it's not allowed in the states because it's not economical to prove that it actually repairs teeth, but I think my understanding is based on some internet comments and nothing else. The studies I've seen haven't proven to effectively repair enamel, I think, but I'm also not scientifically literate enough to understand the p values they report.
I used to buy repair and protect from Canada back in 2017 but haven't used it since then. I periodically check if there is any solid evidence but I haven't seen much or I'm too stupid to understand it.
Regular Sensodyne in other countries has novamin though, and does not have SLS. I've brought home a few tubes from traveling and it seems to work just as well as the US version - I don't get sensitivity back when using it.
What the article doesn't mention is the salivation that Neem twigs cause! Neem trees also produce a biocide called azadirachtin and although the concentration is low in twigs maybe it helps clean the teeth when used a lot?

But I think the more common prehistoric tooth problem was severe wear from using the teeth to process things like fibers and hides.
I think it was fairly rare in Europe, but IDK how well those numbers capture what was common for the majority of the human population living elsewhere.
The first English king to be definitely alive on their 70th birthday (though no longer "in office") was Philip of Spain (jure uxoris) in 1597, so not a medieval king. That is Early Modern Age.
Elizabeth I. didn't make it, though barely, and so the next to reach 70 was George II. in November 1753! Only since the second half of the 18th century is it common for British monarchs to reach their seventies.
Richard Cromwell lived to be 85, but he was never a king, only Lord Protector.
Edgar Aetheling lived to be 73, but he was never king either, due to certain William arriving en force from Normandy.
Assassination definitely brings down the average. But a fair number of English monarchs managed to die in bed. (I was gonna write British, but no: the Scottish kings practically never died in bed. Unless they were stabbed in their sleep.)
As for the common folk, if you look at actual medieval cemeteries that were excavated and studied, the peasants didn't live long either. The age of death can be assessed by looking at the bones, and already the above 50 cohort is somewhat thin, while the above 60 is infrequent.
You underestimate the effects of hunger on mortality. Prior to introduction of potatoes (e.g., ~ 18th century in much of Europe), failed crops would be a common occurrence, happening ~5-6 times during life of a normal rural person. If two of them happened back-to-back, the resulting mortality was already serious, and older people would often be victims. It made sense to use whatever food was left for the younger, stronger generation which was still able to work.
Famine was basically never a concern for the royalty. We have a record of the English king going dinner-less once, but that is not a threat to your life.
BTW If you really want to find a relatively long-lived sector of the society, it would be the high clergy, which had all the upsides of noble life (food, warmth in winter) and almost none of the downsides (most wouldn't fight, murder was less common). This is the only "job" which saw some 70 y.o.s still alive and active, mostly as cardinals.
I did not dispute that this was likely rare in medieval Europe (for the same reason you cite).
This is absolutely untrue. What is your reference?
Never in history have so many people had such "good" looking teeth, but they involve an enormous amount of prosthesis and amalgam. Veneers aren't good teeth, they're intentionally destroyed teeth used to root false teeth.
And brushing, although it keeps teeth clean and not stinky, deepens the gum pockets around teeth that host the microorganisms that will eventually uproot them.
Check out Nutrition and physical degeneration book by Weston Price.
All you need to do is to look at the pictures in the book, you don't even need to read it.
You could chew on your fingernails...
This is about tooth paste, not a supplement
The question is one of optimization. What size (mechanical) or what type of keratin is most suitable, or do we depolymerize (chemical) it first or let oral enzymes do it..? Is brushing as-is sufficient or do we need a longer dwell time..?

Suitable chemical methods:
https://www.sciencedirect.com/science/article/abs/pii/S01418...
IDK how to tell what brand uses what type without independent testing or taking their word for it. Several makers have come out and said needle-shaped is cheaper to buy so if a brand has 10% formulation as opposed to 1 or 3 or 5%, it is more likely to be using needle-shaped. (And there is a separate conversation to be had whether 10% is needed/ideal concentration anyway)
My dentist says that NHAP is great if you have lots of cavities or drink lots of acidic drinks like soda, but once your enamel is repaired too much of NHAP can actually cause weird growths.
Dave's toothpaste has both NHAP and flouride (and the sensitivity agent used in Sensyodyne) if you're looking for the best of all worlds in the U.S.
And has an RDA of 101. Why on earth would a toothpaste meant for sensitivity have this high of an RDA? (Non-whitening sensodyne is around the 40s)
SuperMouth also looked like a great option with an RDA of 67 (particularly for kids who like crazy flavors), and Elims also looked good for anyone who doesn't mind the 92.71 RDA. Ollie stood out for its minimal ingredients list, but turned out to have a relatively high RDA of 143.
I currently use BioMin C in the morning and F at night, but based on everything I'm learning right now about nHAP, I figure it can't hurt to stack Dr. Jen with those. Maybe in a few years I'll get some keratin in the mix too.
It always seemed very interesting in a cynical way that Sensodyne Repair and Protect has a European version with hydroxyapatite but doesn't offer it in the US. The only reputable US brand I'm aware of is Dr Collins Biomin, which is excellent but weak on the hydroxyapatite.
I'll be abused for it here, but I'm intractably convinced the ADA and generally despicable US health industry prefer to avoid it due to its efficacy and how much revenue would be lost if it were more common. Say what you will against this, and I'll remain convinced.
Biomin is cleaner, but weaker.
I generally choose Apagard though. If you do too, the Premio is a good version with a substantial hydroxyapatite content.
Try to buy from a reputable seller if Apagard. I'd not worry about Biomin much.
Edit: also note that these are rinseless pastes, intended to remain on the teeth for as long as they linger. This is where Biomin has an advantage, being cleaner. Spitting is fine, but rinsing will reduce efficacy.
Edit II: Some will wail in disagreement. I think a waterjet can literally add years to the average lifespan while helping with oral health. Maybe consider one, with simple design and minimal features.

That said, I'm not surprised people argue against it. But my teeth haven't "crumbled" after more than a decade of regular apatite use, and that's under various impacts and hard use. If there's any validity to her concerns about it, she should actually discuss them, instead of talking about charcoal and her friend.
While not sold directly in the US, Sensadyne with Novamin is available from Amazon (usually from India).

Have you noticed something more promising ? I am not sure, because I typically do not eat carbs.
Hard to brush that one off!
[that was brilliant, you missed your calling. I am completely enamled :D]
Use the mouthwash once a week and you're good. If your dentist doesn't tell you about it and you don't have great teeth, its ONLY because they want to make more money off of you.

Conclusion Review shows that Novamin has significantly less clinical evidence to prove its effectiveness as a remineralization agent in treating both carious and non-carious lesion. Hence, better designed clinical trials should be carried out in the future before definitive recommendations can be made.
For Novamin alone, I've seen and understood the claims of sensitivity protection with hydroxyl-carbonate apatite (HCA). The paper explains it in 4.3. The layer is temporary and protects from acids, conserving the teeth tissue below.
But F is essential and my paste has it together with Novamin. It seems they may work well together. But the paper also explains that F works with saliva rich in minerals to repair the enamel. So if Novamin creates a strong layer, it may block access of F + saliva to enamel (my speculation, as in 4.2 they say "A clean tooth surface is required to access the mineral-deficient spot.").
So maybe a classical Ca+F paste is better overnight when no acid exposure is expected, but Novamin is nice in the morning before breakfast.
I typically brush after meals, not before, but however you do it is better than not doing so at all.
EDIT: Technically plaque forms faster but only hardens into "tartar" after about 24 hours or more.
EDIT2: There is another reason to avoid brushing you teeth immediately after a meal. Supposedly they're softer due to higher acidity or something along those lines. It's recommended to wait 30-60 minutes after a meal before brushing.
Long story short, it didn’t work out in military applications and ended up being purchased by a toothpaste maker. They couldn’t bother getting it FDA approved for toothpaste so it is not available in the USA. Que conspiracy theories.
I dunno, but I also feel some heat when I chew on cinnamon.
> The treatment could be delivered through a toothpaste for daily use or as a professionally applied gel
Could. In other words, they haven’t even tested if a toothpaste is viable, yet the title is written as if this is a ready-made and proven product.
I wonder how they got the idea to put some in it
Hey Siri, remind me in three years to look for keratin based toothpaste.
https://www.theguardian.com/science/2017/jan/09/decline-of-t...
This simply isn't true. I've chipped two teeth at separate times. Both healed up over the years. I still have all my teeth, including wisdom teeth. No dental work in my lifetime.
They….did not. Maybe the sharp edges eroded into smoother curves, and the nerve acclimated so any sensitivity resolved, but your teeth did not “heal” as in “replace the lost portion”.
I can assure you that is exactly what happened, because one was a vertical chip out of the front of my tooth, like a small rice grain. For my tooth to "wear down" to hide it, I would have had to lose all the enamel on the front of that tooth, which did not happen.
As for the other, where I lost the corner of a front tooth, I suspect my old dentist in my hometown still has an xray, because my parents took me in. He offered to crown it and I declined, choosing to live with the chip. Good thing I did that, since it healed up.
If keratin toothpastes can be produced more economically they could be a better option for mass adoption. For anyone who wants to try nHA toothpaste for remineralization, I can only recommend Sangi Apagard Royal toothpaste ($$$) but it does work quite well when used as directed.
Thats... substantially more expensive than regular toothpaste. Which costs ₹100-₹200 or $2-3.

Is this mechanism different?
If this were effective, our bodies would probably be doing it already.
Just to clarify: even if 2 people had the exact same genetic coding for proteins, but different coding of promoter regions, then these will have different binding affinities, modulating when proteins will or wont be expressed and at what rate. So when considering a population's genome statistics, there is already a spectrum of promotor region codes in the population, if this keratin presence on teeth had significant advantage, selection pressure would already have increased that level towards optimum.
The only caveat for my reasoning would be if it were discovered that this is exactly what happens in a healthy mouth, and that we recently discovered that conventional toothpastes have been stripping such layer of keratin by abrasion.
Naaah, this is not how evolution works. Tooth decay was not as big of a problem for our ancestors than it is for us (more sugar and acidic soft drinks) and tooth decay becomes more of a problem for older people that already reproduced making good teeth above a certain age uninteresting from an evolutionary standpoint. (And mayebe instead of better teeth we learnded to feed grandparents soft porridge to keep them around longer for babysitting duties ;-) (see the usefulness of aunts in elephants). Just because you like to keep your teeth, doesn‘t mean that nature cares.
Gums and Collagen - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7570157/
* As far as I understood, calcium needs a scaffold to attach to bones and teeth - collagen, as in gelatine, can seemingly support the regeneration of the gums, as well as some limited regeneration of the teeth
* Personal Note: I used to have knee pain in my twenties when I still ate a standard diet, when I took collagen it took about a month until the knee pain went away
* Teaspoon in the morning was enough
* Overdosing on Collagen might create some problems - might wanna read up on this
