Something I did not include at the time was the fact that I have always suffered from mouth ulcers, and that the incidence of those has markedly decreased since I started using the tooth soap to brush my teeth. Well, recently I got a sample of new toothpaste in the mail and, by golly, I tried it. Yum, it tasted good and foamed up nicely. After a couple of brushings, though, I began to notice a couple of swollen areas on my lips, one on the top and one on the bottom. I recognized the beginnings of those old, too-familiar aphthous mouth ulcers and immediately stopped using the toothpaste. The swollen bump on my lower lip went away within a couple of days; the one on my upper lip is now a tiny aphthous ulcer. (Sigh.) When will I learn.
I happened to hear a doctor on a radio talk show recently mention that an ingredient in toothpaste called sodium lauryl sulfate has been linked to mouth ulcers and I decided I would do some google searching. I’m reprinting an article below from mouthulcers.org that explains that connection. I thought it was an important article and wanted to share.
It’s back to the tooth soap for me and I am happier – and healthier – for it. If you suffer from mouth ulcers as I have, you may want to consider reading about and trying The Perfect Prescription, tooth soap.Toothpaste and SLS
Sodium Lauryl Sulfate (SLS) is found in almost all readily available toothpastes, and mouth washes. It is what makes the toothpaste go all nice and foamy when you brush your teeth, however, there is nothing else nice at all about putting this chemical in your mouth!
Also known as: Sodium dodecyl sulfate, Dodecyl sodium sulfate, Lauryl Sodium Sulfate, Sodium Laurylsulfate, Sulfuric acid monododecyl ester sodium salt.
Sodium Lauryl Sulfate is a cheap anionic surfactant used in cosmetics and industrial chemicals as a cleansing agent (it is a detergent).
In absorption, metabolism and excretion studies Sodium Lauryl Sulfate has had a degenerative effect on the cell membranes because of its protein denaturing properties. High levels of skin penetration may occur at even low use concentration. Residual levels are maintained in the heart, the liver, the lungs and the brain from skin contact.
It is momentarily comforting to know that SLS is used routinely in clinical studies - until you realise that SLS is used as the "Standard Dermatological Irritant" by which others irritants are measured! Thus, despite being the number one active ingredient in virtually all soaps, shampoos and cleansers, the sole purpose of using SLS in clinical studies is to cause skin irritation that can then be used to identify the properties of other chemicals!
Still other research has indicated SLS may be damaging to the immune system, especially within the skin. Skin layers may separate and inflame due to its protein denaturing properties.
SLS is a contributory factor in the occurrence of mouth ulcers for a lot of people, avoiding it has definitely reduced the frequency and severity for me. For some people, eliminating SLS has completely eliminated their ulcers. If you suffer from recurrent mouth ulcers, it is certainly worth switching to an SLS-free toothpaste - use it exclusively for a couple of months and see if it helps.
To read more simply type "SLS irritant" into the Google search box.
SLS is not the only irritant, some toothpaste manufacturers use other detergents which can also cause problems, make sure yours doesn't have any other horrid ingredients in it, Protect Your Mouth.
