The most common detergent/surfactant in toothpaste is sodium lauryl sulfate (SLS). SLS is the substances that produces the foam when you start brushing and also helps pull food particles and stains away from teeth.
SLS can be derived from coconut or palm kernel oil and has been used in toothpastes for over 50 years.
Despite the scientific research that points to SLS being a safe ingredient; a small percentage of people do seem to be allergic to it.
While there is no conclusive evidence that SLS toothpastes cause mouth ulcers and dry mouths; there is sufficient evidence to support the theory that SLS can inflame an existing mouth ulcer problem.
Lots of consumers who are never troubled with ulcer problems are still on the look out for the safest toothpaste. As SLS is also found in soap, shampoo, lotion, and many other products, some folks shy away from wanting it in a product that you put in your mouth and maybe even swallow.
The are plenty of SLS free toothpaste options out there for those who would prefer to give SLS a miss, but don’t expect the same brushing experience, you won’t be getting a mouthful of foam when you brush.
For those who do suffer from mouth ulcers it has to be worth trying the SLS free option.
Who wouldn’t want to avoid getting anymore mouth ulcers – Ouch!
