Another day another visit to the dentist – today the beginning of a crown and an hour in the chair - what fun. And I am back tomorrow.
I now have to use toothpaste for sensitive teeth – apparently it makes a coasting on the teeth to protect them a bit, as well as containing an ingredient which can get into the teeth as a substitute for calcium. As someone who loves natural, (nasty) chemical free products, this is a bit hard for me.
Did you know modern toothpaste contains these ingredients:.
- sodium monofluorophosphate (not to be confused with MSG)
- flavouring – usually peppermint, spearmint, and wintergreen.
- foaming agents – sodium lauryl sulfate (SLS) that terrible stuff
- Triclosan, an antibacterial agent
- humectants (prevent the paste from hardening)
- Strontium chloride or potassium nitrate for sensitivity
That's why there are warnings on the tube not to eat the stuff.

Arm & Hammer marketed a baking soda-based toothpowder in the United States until about 2000, and Colgate currently markets toothpowder in India and other countries. I still use bi-carb for teeth cleaning now and again – which is also in some modern toothpastes. One hundred years ago I may have used this tooth powder which your poured from a tin, rather than in a glass jar.
