Have you ever experienced sore, red cracks at the corners of your mouth that just won’t seem to go away? If so, you may be dealing with a condition known as angular cheilitis.

What is Angular Cheilitis?

Angular cheilitis, also referred to as perleche or angular stomatitis, is a common inflammatory condition characterized by painful cracks or fissures at the corners of the mouth. These fissures can cause discomfort, pain, and even bleeding, making simple tasks like eating or speaking a challenge.

Causes of Angular Cheilitis

Angular cheilitis can have various underlying causes, but two primary factors are often associated with its development:

  1. Loss of Vertical Dimension: In some cases, angular cheilitis can be caused by a loss of vertical dimension, where the mouth fails to close properly due to factors such as missing teeth or ill-fitting dentures. This can create an environment conducive to moisture retention and bacterial growth, leading to inflammation and infection at the corners of the mouth.
  2. Nutritional Deficiencies: Deficiencies in certain vitamins, particularly vitamin B2 (riboflavin), vitamin B3 (niacin), and vitamin B12, have been linked to angular cheilitis. These vitamins play essential roles in maintaining healthy skin and mucous membranes, and their deficiency can weaken the skin’s barrier function, making it more susceptible to irritation and infection.

Symptoms of Angular Cheilitis

The symptoms of angular cheilitis can vary from person to person but often include:

  • Pain, tenderness, or burning sensation at the corners of the mouth
  • Redness, swelling, or inflammation
  • Cracks, fissures, or splits in the skin, which may bleed or crust over
  • Itching or discomfort when opening the mouth or eating

Treatment and Prevention

The treatment of angular cheilitis depends on the underlying cause but may include:

  • Addressing Nutritional Deficiencies: If angular cheilitis is associated with vitamin deficiencies, supplementing with vitamin B complex or specific vitamins such as riboflavin, niacin, and B12 may help improve symptoms and prevent recurrence.
  • Maintaining Oral Hygiene: Practicing good oral hygiene, including regular brushing, flossing, and using an antifungal or antibacterial mouthwash, can help reduce the risk of infection and inflammation at the corners of the mouth.
  • Addressing Dental Issues: If angular cheilitis is caused by a loss of vertical dimension or ill-fitting dentures, addressing these dental issues may be necessary to alleviate symptoms and prevent recurrence.

By addressing the underlying causes and taking steps to promote oral and overall health, individuals can effectively manage and prevent angular cheilitis. If you’re experiencing persistent symptoms, it’s essential to consult with a healthcare professional for proper diagnosis and treatment.
