What do cracks in the corners of my mouth indicate?

Cracks in the corners of the mouth may be caused by a condition called angular cheilitis. It's usually associated with a bacterial or fungal infection. Angular cheilitis can affect anyone, but is more likely to occur if you:

  • have undergone head or neck radiation
  • have diabetes
  • are deficient in iron or certain vitamins (folate and vitamin B12)
  • have poor-fitting dentures

Talk to your doctor if you develop cracks or breaks in the skin, other sores, or tenderness at the corner of the mouth.

Cracks in the corner of your mouth are a symptom of B Vitamin deficiency. Additionally, this condition could lead to a sore tongue and sores in your mouth.
