4. Be Careful With Toothpaste
Toothpaste residue sitting in the corners of your mouth can irritate sensitive skin. After brushing, gently rinse and wipe the corners dry.
If irritation continues, consider switching temporarily to a mild, non-whitening toothpaste without strong flavoring.
5. Consider an Over-the-Counter Antifungal Cream
If the cracks are:
-
Red
-
Slightly swollen
-
Burning
-
Not improving after several days
A mild fungal overgrowth could be contributing.
In that case, you can use an over-the-counter antifungal cream containing clotrimazole 1%. Apply a thin layer twice daily for 1ā2 weeks. Allow it to absorb, then apply a protective barrier on top.
Avoid using steroid creams without medical advice, as they can sometimes worsen fungal-related irritation.
