Desensitizing Toothpaste Tips

  • Don't rinse after brushing for at least 30 minutes. Pro-Argin Sensitive Pro-Relief These toothpastes need time to work like they should. By spitting thoroughly instead of rinsing your mouth with water after brushing, you'll allow the thin coating of toothpaste remaining on your teeth to get to work providing the relief it is designed give you.
  • Start experimenting with Calcium Based Desensitizing products first. Not all these toothpastes work best for everyone, and it is best to try out different types. Since the Calcium Based Desensitizing Toothpastes are designed for more immediate relief, it is best to try them first. I prefer beginning with Colgate's Pro-Argin Sensitive Pro-Relief Toothpaste based on the available literature. Make sure you don't forget out tips regarding your diet for sensitive teeth, and oral hygiene tricks for sensitive teeth.

Potassium Desensitizing Toothpastes

How They Work:

  • High concentrations of potassium ions depolarize nerve endings in the pores of exposed dentin, and keep them from sending pain signals.

Potassium Nitrate Toothpastes


  • Can work in spite of acid erosion and abrasive events during the day, which open pores on exposed dentin causing tooth sensitivity.


  • Can take up to 2-4 weeks for maximal effect, so stick with it.


  • Sensodyne and the vast majority of desensitizing toothpastes you'll find on the market.

  • Elmex Sensitive Professional Toothpaste (owned by Colgate)

How to Buy:

  • If you live in the US, Pro-Argin toothpastes can be hard to find. Although you can purchase Colgate Sensitive Pro-Relief with Pro-Argin from Canada, the US version has the exact same label with different ingredients, which makes it confusing to purchase. All the same ingredients are present in Elmex Sensitive Professional toothpaste (not in other formulations of Elmex), and you can find this toothpaste online without all the confusion. Until the FDA approval process is completed, buying Elmex Sensitive Professional online is the best way to get Pro-Argin toothpaste if you live in the US.
