Cracked Corners of Lips - Cheilitis
Q. Dr. Brayer, I have cracking and soreness at the corners of my mouth. Someone told me it is Vitamin B deficiency. What can I do about it?
A. You have a common condition called Angular Cheilitis and it is rarely caused by vitamin deficiency. The usual cause is moisture and saliva that builds up from lip licking, poor fitting dentures or drooling at night. The chronic moisture can lead to a bacterial infection or candida (yeast) infection. Cracking and fissuring at the corners of the mouth can be painful and more licking just keeps it going.
Usually it an be cleared up with a combo of an anti-fungal and steroid cream.
