                                The painful condition of dry, cracked corners of the mouth, medically known as angular cheilitis, is a common issue that often signals an underlying nutritional problem. A deficiency causes dry cracked corners of mouth when the body lacks specific vitamins and minerals crucial for skin health, most notably certain B vitamins and iron. Understanding these deficiencies is the first step toward effective treatment and prevention.
