Sodium Lauryl Sulfate and Apthous Ulcers

By Deirdre E. Mueller, editor

Recurrent fever blisters, canker sores, and toothpaste

Some people suffer from recurrent apthous ulcers, commonly known as fever blisters or canker sores, inside the mouth. There is a possibility that recurrent apthous ulcers may be due to an allergic reaction to a common foaming agent in toothpaste known as sodium lauryl sulfate.

There is an all-natural toothpaste that contains no sodium lauryl sulfate that I have recommended to our patients for years: Rembrandt Natural. Since Rembrandt Natural contains no sodium lauryl sulfate, it can be used by those patients who may be suffering from this allergic reaction. Also, containing only natural ingredients, the toothpaste is gentle enough for our patients to use on two-week and six-month bleaching programs.
