Angular Cheilitis: Symptoms, Risks & Treatment

Angular cheilitis (also called perlèche, angular stomatitis or cheilosis) often begins when the corners of the mouth stay moist for a long period of time. When the saliva dissipates, dryness and irritation move in. When a person repeatedly licks their lips to alleviate the dryness, the mouth area can dry out even more and crack, allowing germs to enter and cause an infection. The moist environment can also allow for fungal growth, resulting in a candida or yeast infection that itches and burns. Mouth patches may also appear scaly, white in colour, swollen or blistered.

This condition can affect patients of any age, from babies to the elderly. People with weakened immune systems from a condition such as diabetes or HIV are especially vulnerable. Other risk factors, include:

• Excess saliva pooling in the corners of the mouth
• Thumb sucking
• Ill-fitting dentures
• Certain genetic conditions, such as Down syndrome and Sjögren's syndrome
• Nutritional issues, especially a lack of B vitamins or an iron deficiency.

Depending on the cause, your doctor or dentist may prescribe dietary changes, vitamin supplements or an antibiotic to treat the condition, notes Dermatology Advisor. Don't just apply lip balm and ignore it. Your health care professional will be able to tell whether your issues are caused by a fungus, germs or a more dangerous underlying condition, such as an immune disorder.

Angular cheilitis caused by candida is often treated with a steroid or antibiotic cream, the same way as other fungal infections. If you regularly have non-food objects in or near your mouth (such as dentures, cigarettes or braces), good oral hygiene can help keep your lips and mouth clean and free from infection. Try to keep your lower face dry and wear lip balm with SPF protection in especially cold, dry or sunny weather.

It is best to visit a doctor or dentist as soon as possible to get this type of infection treated properly. Early treatment can help clear up an infection or symptoms in as little as a few days, so don't waste time waiting to smile again!
