Is Angular Cheilitis Contagious?


Angular cheilitis is marked by inflammation of the corners of the mouth. Sensitive, sometimes painful sores appear when the corners get irritated. Without intervention, the corners of the mouth can become dry and lesions can appear. Angular cheilitis is caused by fungal infections, bacterial infections or a combination of the two. Unlike other conditions of the mouth like cold sores, angular cheilitis is not contagious. It can spread from one corner of the mouth to the other, but it cannot move on to other parts of the body.

If you are affected by angular cheilitis, you may find your lips are dry and uncomfortable. They may also feel like they are burning and you may have an unpleasant taste in your mouth. In cases of severe cheilitis, it may be hard for you to eat and you may not receive sufficient nutrients.

What causes angular cheilitis?

Health professionals ascertain the cause of angular cheilitis by swabbing the corners of the mouth and nose and testing for the presence of bacteria and fungi. Doctors also examine your mouth and pay close attention to cracks, redness, swelling and sores. They may also inquire about any regular practices you undertake that could affect your lips.

Angular cheilitis is usually caused by a specific fungal infection – candida, which is a type of yeast. You are more likely to develop angular cheilitis if the corners of your mouth are often moist. Reasons for this include wearing braces or ill-fitting dentures, licking your lips a lot and sucking your thumb. Sagging skin around your mouth, crooked teeth or a lack of vitamin B or iron may also be responsible.
In addition, certain medical conditions like anemia, diabetes, cancers of the blood, immune disorders and Down Syndrome can make angular cheilitis more likely. Diabetics tend to get fungal infections because candida feeds off glucose. Diabetes also weakens the immune system and this makes it harder to fight infections.
