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.

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.

I don't think you can blend hair into a paste you can then spread over your teeth. This is about tooth paste, not a supplement

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..?

You have clearly not dealt with hair and mechanical devices.

Starchy food led to rotten teeth in ancient hunter-gatherers:

But I think the more common prehistoric tooth problem was severe wear from using the teeth to process things like fibers and hides.

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.

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 leaves a bad taste in the mouth.

But why not chew on hair directly?

Because you'll get a bezoar (hairball).

Not if you drink coca cola, which is even listed in medical books as a way to disolve it. You might get IR though :)

average, yes, but living to 70 was reasonably common if you made it past childhood.

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.
