How to Heal a Sore in the Corner of Your Mouth

The corner of the mouth is an area we often overlook until something goes wrong. Pain, redness, or a frustrating sore can quickly turn daily activities like eating or talking into painful chores. This condition, known as angular cheilitis, is common but can be treated with the right care. Let’s dive deep into understanding, preventing, and treating these sores.

Understanding Angular Cheilitis

Angular cheilitis presents as a dry, inflamed, sometimes crusty sore that can occur on one or both corners of the mouth. The discomfort it causes can range from mild to intense.


    • Fungal or bacterial infections
    • Nutritional deficiencies
    • Environmental factors, like cold and windy conditions
    • Saliva buildup, possibly due to lip-licking or drooling

Immediate Relief Measures

  • Lip Balms and Moisturizers: Use a protective lip balm to prevent further irritation and to keep the area moisturized.
  • Cold Compress: Applying a cold compress can reduce inflammation and provide relief from itching.

Long-Term Treatment Options

  1. Topical Antifungals: If the sore is caused by a fungal infection, antifungal creams like clotrimazole can help.
  2. Antibacterial Creams: Useful if bacteria is the cause, though a prescription might be required.
  3. Steroidal Creams: These can reduce inflammation, but should be used under supervision as they can exacerbate fungal infections.
  4. Supplementation: If the cause is nutritional deficiency, supplementing with B vitamins, iron, or zinc might be advised.

Home Remedies to Try

  • Coconut Oil: Its antifungal properties can combat fungal causes of angular cheilitis.
  • Honey: This natural antibacterial can help fight against infection.
  • Aloe Vera: It provides soothing relief from pain and inflammation.
  • Cucumber: Placing a slice on the affected area can offer cool relief.

Prevention is Better than Cure

  1. Stay Hydrated: Keeping your body hydrated can prevent dryness around the lips.
  2. Avoid Lip Licking: Constant moisture can create a conducive environment for bacterial and fungal growth.
  3. Use Lip Protectants: Especially in harsh weather conditions.
  4. Maintain Oral Hygiene: This minimizes the chances of infections.


Q: How long does angular cheilitis take to heal?

    • A: With appropriate treatment, it can take a week to ten days. Severe cases might take longer.

Q: Is the condition contagious?

    • A: While angular cheilitis itself isn’t contagious, the bacterial or fungal agents causing it might be.

Q: Can toothpaste worsen the condition?

    • A: Yes, certain toothpaste ingredients can irritate the sore. Switching to a milder toothpaste can help.

Consulting a Professional

Persistent or frequently recurring sores should be a signal to consult with a dermatologist or healthcare professional. They can provide a precise diagnosis and guide you towards the most effective treatments.

In Conclusion

Angular cheilitis, while common, can be a major discomfort. Recognizing the symptoms early on and implementing effective treatments can go a long way in managing and overcoming this condition. With proper care, you can ensure your lips remain pain-free and healthy.
