Angular cheilitis

Angular cheilitis (also called perlèche, cheilosis, or stomatitis) is a condition with deep cracks and splits at the corners of the mouth. If severe, the splits or cracks may bleed when the mouth is opened and a shallow ulcer or a crust may form.

Possible causes of angular cheilitis include:

  • Infection. Fungal infections are the most common, but viral or bacterial infections can also occur.
  • Nutritional deficiency of vitamin B.
  • Over-closure of the mouth in someone who has been without teeth or dentures for some time.

In young children, the cracks and splits often begin with lip-licking, biting the corners of the mouth, or thumb-sucking.

Treatment depends on the cause and can include lip lubrication, antifungal and antibiotic medicine, vitamins, and dentures for a person without teeth.

Due to the threat of the COVID-19 (Coronavirus), we are taking precautionary measures to protect our staff and patients. We are implementing a temporary NO VISITOR policy at this time. Only patients or patients and their guardians will be allowed into the office. Please note, this is not to inconvenience anyone! The virus is a very real threat and it is essential that we stay healthy in order to provide needed care for our patients. If you are sick, we ask that you CALL the office to speak with a nurse before you come in. The nurse will provide specific instructions for you. Please DO NOT enter the office if you are sick (upper respiratory symptoms, fever, cough, or flu like symptoms). We are closely monitoring the situation and will update you as circumstances change. Thank you for your understanding!!
