Tooth brush and tooth paste were still unknown. The health of teeth in Germany in Stone Age was quite well; mostly without dental caries. However, the abrasion of the teeth, determined by the grinding of corn which contained sand was very high.
Fir cleaning teeth one would take – like in Africa still in modern times – small branches, like from grazing land, with the end full of loose fibres.
The condition of the teeth is first degrading from the iron Age onwards, probably due to the larger intake of honey and honey wine.
