Hey Siri, remind me in three years to look for keratin based toothpaste.

Re: Toothpaste made with keratin may protect and repair damaged teeth: study
#93Was thinking about oddities of language recently (happens a lot since moving to Germany), specifically how "toothpaste" isn't made from teeth and "tomato paste" isn't something you rub onto a tomato. So anyway, should we be calling this "hairpaste for teeth", or "toothpaste from hair"?
This semantic variability in the relation between the two nouns of a compound is pretty common in compound nouns: "Y made of X", like "tomato paste", "Y used (somehow) for X" (like "toothpaste", "paintbrush", "electrical outlet"--here an adjective, but still a lexicalized phrase), "Y in X" ("treehouse"), "Y for X" ("doghouse"), "Y containing X" ("paint can"), not to mention metaphorical uses, with some etymological r…
“Windows Subsystem for Linux” is probably the most confusing example of this (an environment subsystem which provides a Linux userspace to a Windows NT kernel). more intuitive would be to call it a Linux Subsystem for Windows, but presumably for branding purposes they wanted Windows in front.

#95So, chewing on beetle exoskeletons would repair teeth enamel? Wonder if there is archaeological evidence of humans doing that. Edit: there seems to be plenty of evidence of eating insects but any dental association is probably incidental (pun not intended). Maybe we just haven’t been looking into the enamel for these structures.
Did past humans have the dental problems we have? I imagine a lot of our problems are caused by our diet and access to sugar.

#96I recently started using a nano-hydroxyapatite based toothpaste. It can't restore enamel but does better at remineralization than fluoride, hopefully it will be a good intermediate for me until something regenerative is available.
Hydroxyapatite based paste is incredible, and has astonished a few of my incredulous friends dealing with dental problems. 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 h…
I pick up a couple tubes of that Sensodyne every time I’m in Europe.

It seems to me the two are effectively the same unless you have significantly misshaped teeth (remineralizing vs regenerating). I also use hydroxyapatite, just to reduce my fluoride exposure, although I believe fluoride is supposed to be a more potent remineralizer (and fluorapatite is allegedly stronger than natural hydroxyapatite). But the upside is that I don't mind swishing hydroxyapatite around in my mouth for 1…
NHAP particles are smaller than fluoride particles, so they're able to penetrate farther into the porous surface of the teeth; flouride basically can only coat the surface. There is some research indicating that NHAP is more effective than flouride at remineralizing (e.g. https://pmc.ncbi.nlm.nih.gov/articles/PMC4252862/ ) but that flouride is more protective than NHAP because NHAP isn't protective at all. (The flour…
>Dave's toothpaste has both NHAP and flouride
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)

average, yes, but living to 70 was reasonably common if you made it past childhood.
I was under the impression living to 70 would have been very rare in, say, 1100 CE
Not deeply knowledgeable here but imagine this depended quite a bit on where you were living in 1100 CE.
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.
Re: Toothpaste made with keratin may protect and repair damaged teeth: study
#100The picture says "enamel-mimicking" and the text says "protective coating that mimics the structure and function of natural enamel", so it looks like a protective layer, not true repair. I've been using a paste with novamin lately, it also creates a protective layer and is also marketed as "repair". I like it and feel some heat when it contacts with teeth, so the chemical reaction must be working. But the marketing l…
The image with the cross section looks convincing. I don’t really know what I’m looking at.
