Angular cheilitis is a common condition affecting the corners of the mouth. Many people wonder about its causes, particularly whether close contact like kissing can lead to its development or spread. This discussion aims to clarify what angular cheilitis is and address common concerns about its transmission.
What is Angular Cheilitis?
Angular cheilitis is an inflammatory skin condition that affects one or both corners of the mouth. It is characterized by redness, cracking, and soreness at the angles where the upper and lower lips meet. The affected areas can also show signs of bleeding, blistering, crusting, or maceration, where the skin appears soggy and lighter in color. While often painful, angular cheilitis is not considered a serious condition.
This condition is also known by other names such as angular stomatitis, cheilosis, or perleche. The symptoms are primarily localized to the mouth corners, though inflammation may slightly extend to adjacent facial skin or lips.
Is Kissing a Cause or Transmission Route?
Angular cheilitis is not caused by kissing, nor is it considered contagious like a cold or flu. The condition is an inflammation of the skin at the mouth corners, which can be triggered by various factors, rather than being directly transmitted through casual contact.
However, an underlying infection that contributes to angular cheilitis, such as a yeast infection or a bacterial infection, could potentially be transmitted through close contact. For example, oral yeast (Candida) or certain bacteria like Staphylococcus can thrive in the moist environment that often precedes angular cheilitis. While the angular cheilitis itself is not transmitted, the microorganisms that can complicate it might be exchanged.
Common Factors Leading to Angular Cheilitis
Angular cheilitis develops when saliva collects at the corners of the mouth, leading to dryness and cracking of the skin. This moist environment can become a breeding ground for microorganisms. Fungal infections, particularly Candida albicans, are a common cause, often leading to a yeast infection. Bacterial infections, such as those caused by Staphylococcus species, can also contribute to or superinfect the condition.
Several other factors can create an environment conducive to angular cheilitis. Nutritional deficiencies, especially low levels of iron and B vitamins like riboflavin (B2), cyanocobalamin (B12), and folate, are associated with the condition. Mechanical irritation plays a role, including habits like lip licking, which can keep the area moist and prone to cracking. Ill-fitting dentures or other dental issues that alter lip approximation and increase salivary pooling can contribute. Excessive drooling, certain medical conditions like diabetes, inflammatory bowel disease, or immune system disorders, and some medications can increase susceptibility.
Relief and Prevention
Managing angular cheilitis involves addressing the underlying causes to promote healing and prevent recurrence. Maintaining good oral hygiene is important, as is keeping the corners of the mouth as dry as possible. Applying emollients or barrier creams, such as petroleum jelly, can help protect the skin from moisture and aid healing.
For cases linked to nutritional deficiencies, dietary adjustments or supplements rich in iron and B vitamins may be recommended. If an infection is present, a healthcare professional may prescribe antifungal creams or oral antibiotics, depending on the specific microorganism identified. Consulting a doctor or dentist is advisable for persistent cases, especially to rule out or treat underlying medical or dental issues.
