what causes canker sores in toothpaste
Some people suffer from apthous ulcers, commonly known as fever blisters or canker sores, inside the mouth. There is a possibility that recurrent canker sores may be due to an allergic reaction to Sodium Lauryl Sulfate (SLS). You can find brands of toothpaste made without SLS. So, if you suffer from painful recurring canker sores, it may be worthwhile to invest in toothpaste products that do not contain it.
