Hunter-gatherers, acorns and tooth trouble

It has been commonplace to believe that hunter-gatherers had good tooth health and that it was farming what caused dental problems because as cereals became a staple. There was good reason for that: caries were detected only rarely among hunter-gatherer remains (0-14%) while early farmers had much such painful problems much more frequently.
However the Upper Paleolithic people of Taforalt caves (Rif, North Africa), some 14,000 years ago (Oranian culture), had caries in 51% of adult teeth, a frequency comparable to those of early farmers.
This is attributed to the very high levels of nut consumptions, particularly acorns but also pine nuts, juniper berries, pistachios and wild oats. The number of acorn remains found is so large that the archaeologists had to conclude that they were used as year-long staple.

Taforalt people had hand mills, which they used to process some of these nuts, most likely the acorns, whose consumption as bread has been documented since antiquity.
Another finding are esparto grasses, which the authors believe were used in basketry. However I must mention that this versatile fiber has known many uses, being documented in Neolithic clothing of nearby Andalusia, used for some types of shoes even today and, of course, being a prime material for rope-making.

Oranian culture dates to c. 22,000 years ago, with likely (partial?) roots in the Southern Iberian Gravetto-Solutrean (hence the name Iberomaurusian, although the culture as such is not known in Iberia). It was replaced in the Epipaleolithic by Capsian culture, with ultimate roots at the Nile (and hence the most likely vector of Afroasiatic languages leading to Tamazigh, aka Berber).
