A decade ago I read a book written by Waris Dirie, where she describes how they brushed their teeth in the desert with a tooth stick made out of Neem tree (Salvadora persica). Until then I didn’t pay much attention to the toothpaste, except that I wanted as much herbs in there as possible. Later I found out that in Europe people brushed their teeth with mastic tree (Pistacia Lentiscus or Pistacia Therebintus) tooth sticks or with sticks made of Hazelnut bush. Oil made of mastic gum or leaves helps to keep the teeth in place and prevents paradontosis and kills the bacteria Heliobacter Pylori – as some of the studies state. While in India people used the Neem tree (Salvadora persica).
Well, they certainly didn’t have problems with bacteria loaded toothbrushes – we should disinfect them in alcohol solution, I guess.
Just recently I stumbled upon an explanation that Chinese traditional medicine considers teeth as the endpoints of the meridians.
Here is a Meridian Tooth Chart: http://www.meridiantoothchart.com/tooth_charts.html
What I did notice though is that after using very natural toothpaste (bought or self-made) for some years it also had a healing and soothing effect on my intestines. Actually it worked like daily medicine for my alimentary canal, while the ordinary toothpastes work just the opposite.
Together with the explanation of teeth in TCM I also found an interesting German Tooth gel with 35 various etheric oils to activate each meridian of the teeth. I haven’t tried it, so don’t consider this as an advertisement. It is maybe worth considering this thing called daily mouth hygiene – do we help our intestines with it?
