What causes the little cuts on each side of my mouth? They won't heal!
There are lots of causes for little cuts on each side of my mouth. It can be caused by an infection by yeast or strep infection, dry lips and skin specially during winter, vitamin B deficiency and anemia.
Your mouth gets little split in both sides of mouth, right. I sometimes get this. I think it might be a vitamin deficiency.
That happens.. Use chapstick. Sometimes it cuts because your lips are dry..
I have had this also, and for me it was indeed a vitamin deficiency. Not eating right at a time I was under stress.
