SLS isn&#8217;t automatically a bad ingredient. Millions of people use toothpaste containing it without developing ulcers. The issue is that it can irritate the delicate lining inside the mouth, particularly when you&#8217;re already prone to aphthous ulcers, also known as canker sores.<\/p>\r\n<h3>What the Ulcer Usually Feels Like<\/h3>\r\n<p>It may start as a tender spot. Then you notice a small round or oval sore with a pale center and a red edge. Eating something spicy suddenly feels like a terrible idea.<\/p>\r\n<p>SLS may irritate an existing sore rather than being the sole reason it appeared. Mouth ulcers have several possible triggers, so blaming every ulcer on toothpaste is a stretch.<\/p>\r\n<h2>Switching Toothpaste Is Worth Trying<\/h2>\r\n<p>\u2022 SLS-free is the key detail, not simply a toothpaste that says &#8220;gentle&#8221; on the front.<\/p>\r\n<p>\u2022 Keep fluoride in the picture. You still want a toothpaste that protects against tooth decay.<\/p>\r\n<p>\u2022 A soft-bristled toothbrush makes sense while the sore is healing, especially if brushing currently feels rough.<\/p>\r\n<h3>Give Your Mouth a Break<\/h3>\r\n<p>Once an ulcer appears, don&#8217;t keep poking at it with spicy food or very hot drinks. Soft foods and cooler drinks are easier while it heals. A soft toothbrush helps too.<\/p>\r\n<h2>When It Isn&#8217;t Just the Toothpaste<\/h2>\r\n<p>If you keep getting ulcers despite switching toothpaste, there may be another reason behind them. Stress, irritation from biting the cheek, nutritional problems, or other health issues can play a role.<\/p>\r\n<h2>So, Should You Go SLS-Free?<\/h2>\r\n<p>If toothpaste seems to make your mouth sting or your ulcers keep returning, yes, I&#8217;d try it. It&#8217;s a simple change, and there is enough evidence behind SLS-free toothpaste to make the experiment worthwhile, even though it isn&#8217;t a cure for every mouth ulcer.<\/p>\r\n<p>Visit our page on <a class=\"decorated-link\" href=\"https:\/\/www.envysmile.co.uk\/composite-bonding-london\" rel=\"noopener\" data-start=\"536\" data-end=\"569\"><strong data-start=\"537\" data-end=\"565\">composite bonding London<\/strong><\/a> to explore treatment options, costs, and expert advice.<\/p>","protected":false},"excerpt":{"rendered":"<p>Why SLS Can Be a Problem Here&#8217;s the thing.
