Our ancestors were able to heal tooth decay.
The discovery has beenrecently made by in an ancient cemetery in Sudan where human remains, dating back to 2000 years ago, have been analyzed in laboratory.
The results of the analysis showed that the ancestors had very healthy teeth: less than 1% of them suffered from tooth decay.
All this thanks to the 'Cyperus rotundus', a plant with special antibacterial properties that was used like both toothbrush and toothpaste.
However it is thought that the low percentage of caries is due to the fact that the ancestors, great hunters, ate mainly meat and very few carbohydrates (responsible for tooth decay). With the advent of agriculture everything changed because people started to eat cereals with an increase of tooth decay.
