Potassium Nitrate in Toothpaste


Being a natural product loving mommy, I tend to use natural toothpaste bought from my local health food store.  The other day I was given a new toothpaste to try from my dentist. He just said that is was excellent.  I examined the ingredients and saw potassium nitrate listed as an active ingredient.  
According to wikipedia  potassium nitrate is commonly used in toothpastes such as Sensodyne or Crest Sensitive as a remedy for Dentine Hypersensitivity and is approved as a monographed drug by the FDA.


What is potassium nitrate?
Major uses of potassium nitrate are in fertilizers, food additiverocket propellants and fireworks; it is one of the constituents of gunpowder.  It's also used for food preservation and food additive in the USA.


The problem is when sodium nitrate and potassium nitrate convert to nitrites in your body creating nitrosamines. Nitrosamines are well known carcinogens.

My take?


It has been shown to help people with sensitive teeth issues. It's also a very small amount and you aren't swallowing it (hopefully). However, if you don't have sensitive teeth, then I really wouldn't want to be brushing with nitrates. I think I will stick to my Tropical Traditions tooth cleaner.
