What product(s) do you recommend? I'm in the US.
Dave's is available in the U.S. and has NHAP, flouride, and the anti-sensitivity stuff from Sensodyne.

Toothpaste is not a complicated compound to make. 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..?
The article mentioned "extracting keratin". It might be more a chemical than a mechanical process.

So, 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.
Chewing plant twigs to clean teeth is an ancient way of tooth cleaning in many cultures[1]. I wonder if the Lignin or Suberin in plants acts the same was as Keratin in this study. 1. https://en.wikipedia.org/wiki/Teeth-cleaning_twig
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?

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.
Never in History have humans had as good teeth as they do today. Also consider that until we had vaccines and antibiotics in the early 20th century, the average lifespan was very short.

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.
The 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…

Sure. We can also treat cancer better than ever before, but it would still be interesting to know where the rise in cancer cases came from, even if we can patch around the problem and are better off overall. Same for dental health: my understanding is also that people didn't used to need toothpaste to enjoy a comparable dental health
