Cracks or sores in the corner of the mouth, also known as angular cheilitis, angular stomatitis, or perleche, can be rather annoying, like a paper cut â small, and irritating. Angular cheilitis is actually an inflammatory condition, and can cause bleeding and ulceration in addition to the painful cracks or sores.
Excess saliva on the lips or corners of the mouth can cause cracking and chapping. This could occur from licking the lips too much, or from ill-fitting dentures or missing teeth. Saliva contains enzymes which can damage the skin, and the moisture leaves an inviting environment for an angular cheilitis infection.
