Before we get too ahead of ourselves, do you know the difference between a cold sore and a canker sore? They are also known as mouth ulcers and cause that unbelievably annoying, pain that can affect your ability to eat, drink and just enjoy your daily life. Canker sores: occur only inside your mouth, they aren’t contagious or caused by a virus. Click here to see a chart display the differences and to learn even more about canker sores in-depth. What causes a canker sore? Canker sores are typically caused by damage to the oral tissue in your mouth. This is often due to sodium lauryl sulfate (SLS) – an all too common foaming agent that is an ingredient in most of the toothpastes that are on the market. But NOT TheraBreath toothpaste! You hopefully already know that here at TheraBreath, we are big believers in only using the best quality ingredients and we refuse to include any unnecessary or potentially harmful chemicals, flavors or detergents. So check the ingredients on you (and your children’s) toothpaste. Do you see sodium lauryl sulfate in it? If so, you may want to consider giving it the boot and getting your very own tube of TheraBreath toothpaste. After all, we have enough to worry about in our busy lives; canker sores shouldn’t be an issue. What is SLS? It’s SOAP. It’s a surfactant that can cause damage to the lining of the interior of your mouth and dry it out, causing dry mouth, which you probably know by now can lead to bad breath. Why would oral care companies include this in your toothpaste? SLS creates that foaming action that develops in your mouth when you’re brushing your teeth. While it isn’t actually doing anything to better clean your teeth, gums and mouth, it gives the user the impression that it does. SLS is also used in many shampoos for the same foam-filled experience. Want to learn even more about canker sores and sodium lauryl sulfate?
