New Research Confirms SLS in Toothpaste can Aggravate Cold Sores

When we do the daily routine of brushing, rinsing and flossing at least twice a day, we all have a common goal: a healthy mouth and teeth. However, one specific ingredient in your oral care products may actually be hurting your oral health rather than helping it.

Do you suffer from cold or canker sores? Then you may want to check the ingredients in your toothpaste. Research done by clinical professor of oral biology at the University of California, Los Angeles, Fariba Younai recently gave a talk that discussed sodium lauryl sulfate (SLS) – a common ingredient in many toothpastes.  Dr. Younai’s research shows that SLS can increase the chances of chronic aphthous ulcers (cold sores) for people with less than perfect immune systems.

What is SLS? It’s a surfactant which is a type of foaming or wetting agent found in many of your common toothpastes. It creates the foaming action while you brush with the toothpaste. However, this foam is only to make the user think that the product is more effective, it actually doesn’t have any added benefit – actually the converse. Past studies have noted that SLS can irritate the walls of the inner cheeks, gums and underside of lips where the toothpaste has the most contact with skin.

Dr. Younai suggested the use of TheraBreath toothpaste amongst the recommended brands that are SLS-free. TheraBreath toothpaste does not contain SLS and will not have the same risk of sores developing in the interior of the mouth – just another benefit of using TheraBreath products. Not only do they keep your breath fresh, you also won’t have to worry about dealing with constant and reoccurring painful cold sores.
