One of the biggest culprits believed to bring about canker sores in people with RAS is a chemical called sodium lauryl sulfate. It’s caustic, and it’s in everything, especially toothpastes. Many believe that the abrasiveness in SLS helps to bring about canker sores in people who are susceptible to them. Luckily, there are several manufacturers out there who have created natural and SLS-Free toothpastes just for us.
Here are some that are worth checking out.
Rembrandt has made a name for themselves over the years as a whitening toothpaste, but in the last few years, they have leveraged their good name to address a number of other conditions, including canker sores. Enter Rembrandt C, specially formulated for canker sores. Using Sodium Fluoride instead of SLS, it both whitens and stays gentle for us sensitive types. Comes in mint flavor.
Tom’s has made a name for themselves over the years amongst the… well, let’s just say it, the hippies. Their natural ingredients have always been a draw for those who would rather not put industrial chemicals into their bodies, which made it a natural choice for canker sore sufferers. In their Clean & Gentle version, they use the natural ingredient glycyrrhizin, from the licorice plant. It both creates foaming action to take the place of SLS and is a known ingredient to help soothe canker sores.
If you’ve ever had sensitive teeth, you’re likely very familiar with Sensodyne toothpaste. Their formula has made life liveable for many people who otherwise lived in extreme pain whenever they ate. They more recently introduced their Iso-Active line which is made to foam and reach areas that otherwise weren’t being reached. What most people don’t know is that it is also SLS free. So you can whiten, lessen sensitivity, and avoid canker sores all at the same time.
Biotene’s main reason for being is to cure dry mouth, but it is also SLS free. I’m currently using this toothpaste and will report the results soon. I can say that I haven’t seen a total cessation of canker sores, though they have gotten smaller and less often – it may take some research to see if it’s the toothpaste or the supplements I’m taking right now. I can definitely recommend it for anybody who wants to give it a try.
