Ah, the corners of the mouth (also called angular cheilitis) can be more than just a dryness issue. Here’s a clear explanation of why persistent sores or cracks might appear and what they could indicate:
Common Causes of Non-Healing Mouth Corners
1. Fungal or Bacterial Infection
- Candida (yeast) or Staphylococcus bacteria can cause red, cracked, and painful corners.
- Often worsens with saliva accumulation in the corners.
2. Nutritional Deficiencies
- Vitamin B2 (riboflavin), B3, B6, B12, iron, or zinc deficiencies can lead to cracks that won’t heal.
- Vegans, vegetarians, or those with absorption issues may be at higher risk.
3. Chronic Dryness or Lip Licking
- Constant moisture from saliva and exposure to wind or cold can prevent healing.
- Creates a cycle of irritation.
4. Immune System Issues
- Conditions like diabetes or other immune disorders can slow healing and make infections more likely.
5. Allergic Reactions
- Toothpaste, lip balm, or foods can sometimes trigger contact dermatitis at the mouth corners.
Signs You Should See a Doctor
- Persistent sores > 2 weeks
- Severe pain or bleeding
- Spreading redness or swelling
- Recurrent episodes
Home Remedies (Supportive)
- Keep the area clean and dry.
- Apply petroleum jelly or barrier cream to protect skin.
- Avoid licking or picking the corners.
- Use a mild antifungal cream if Candida is suspected (after consulting a doctor).
- Address nutritional gaps with a balanced diet or supplements.
✅ Bottom Line
If the corners of your mouth won’t heal, it may be more than dryness—infection, nutritional deficiency, or underlying health issues could be at play. Proper diagnosis and treatment are important to prevent recurring problems.
