Angular cheilitis is a condition characterized by inflammation, redness, cracking, and soreness at the corners of the mouth. It is often caused by a fungal infection (commonly Candida), though bacteria such as Staphylococcus aureus can also be responsible. People with diabetes, weakened immune systems, or those who wear dentures are more prone to developing it.
The soreness occurs because the skin in this area is delicate and constantly moving. Moisture from saliva can collect in the corners, creating an environment where fungi and bacteria thrive.
2. When Is It Safe to Self-Treat and When Should You See a Doctor?
In many cases, angular cheilitis can be managed at home. However, seek medical attention if:
- The pain becomes severe
- Redness spreads beyond the corners
- Symptoms last longer than two weeks despite treatment
- You develop fever or signs of a broader infection
If you have diabetes or a weakened immune system, it is wise to consult a healthcare provider sooner.
3. First Step: Gentle Cleansing
Gently clean the area twice daily with lukewarm water and a mild, fragrance-free cleanser. Avoid hot water, as it can dry and irritate the skin further.
Pat the area dry with a soft towel instead of rubbing. Keeping the area clean and dry helps prevent infection and supports healing.
4. Use a Protective Barrier
Applying a thick protective barrier such as petroleum jelly, lanolin ointment, or zinc oxide cream can protect the skin from saliva and irritation.
Reapply after eating or drinking, as moisture can remove the protective layer. Consistent use helps maintain hydration and speeds recovery.
