Toothpaste made with keratin may protect and repair damaged teeth: study

I don't know what this new hairpaste does, but Novamin promotes re-enamelization of teeth, which is where mineral ions like calcium bond themselves to the tooth and fill in small pits and fissures. It's not regrowing actual enamel, it's probably not going to fill in any pits you can see with the naked eye, but it's a real and beneficial effect. Actually any fluoride toothpaste also does this, but Novamin may be a bit more effective at it.

Never heard of Novamin but doesn't look promising?

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.

I use novamin but I can't feel a chemical reaction.

Have you noticed something more promising ? I am not sure, because I typically do not eat carbs.

Try biomin F, newer novamin

The image with the cross section looks convincing. I don’t really know what I’m looking at.

> marketing leaves a bad taste in the mouth.

Hard to brush that one off!

[that was brilliant, you missed your calling. I am completely enamled :D]

Sensodyne toothpaste has two lines: one that contains a mild painkiller (Rapid Relief) and one that [claims to] repair small cracks in teeth (Repair & Protect).

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.

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 relation between X and Y ("moon shot", "crapshoot", "greenhouse"), and so on. Not to mention multi-word compounds, like "greenhouse gas"--but I'm sure you've seen lots of those in Germany :).

“Toothpaste” is the commonly accepted English word (in most English dialects, as far as I’m aware) for that paste which we use to clean our teeth with a brush. So I expect we’ll call it “toothpaste” regardless of the exact chemical composition.

If keratin is the active ingredient, I would suspect the exact source doesn’t really matter.

Indeed.

We expect olive oil to be made from real olives, but not baby oil…

There was some joke where they showed a sign saying “Kinder Kebab, €2”

Thanks for this, I'll be calling it toothhairpaste regardless of what the marketing department comes up with.

Is Baby Oil made from...?

Isn’t it Zahnpasta in German too?

I only clean my teeth with a dentifrice. I do not want to have to risk turning my teeth into paste!

nHA is prohibitively expensive to produce and the most effective process that produces the smallest particles is patent-protected by Sangi, and therefore many nHA toothpaste brands only contain a fraction of the concentration used to produce the effective results reported in academic studies (1-2% instead of 10%).

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.

That's pretty unbelievably fast, actually.

Why do you think he ran out of hair?

Perhaps he had hair before the harvesting

As you can see, he has a beard, so…

Or tested too much..

[flagged]

I'd appreciate that too. My dentist recommended me to use Duraphat, a 9 euro per 50 gram toothpaste.

“The root of the problem” is a more usual usage, but is just as readily applied (ha get it) as “the root of the solution”, especially when a dental pun can be bonded (puns are swell) to the headline (I can’t think of a way to pun on gumline here).

I found the phrasing really difficult to read and understand, even though I got the pun, so you’re not alone in that.

Root as in seed [crystal], as in nucleation point is what I would surmise.

Dentistry pun? Root as in the root of a tooth?

To everyone reading this you should still use flouride! Flouride and nanohydroxyapetite together both strengthen the outside layer of your teeth while strengthening the inside of them. Either alone is good, both together are great.

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 10 minutes, twice a day, so whenever I go to the dentist, I'm the healthiest mouth of the day (not the case pre-hydroxyapatite tooth paste/powder).

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 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.
