The fungus commonly found on the corner of your mouth is typically a candidal infection, which is often associated with a condition known as angular cheilitis.
Understanding Angular Cheilitis
Angular cheilitis, sometimes referred to as perlèche, is a long-term inflammation that affects the corners of the mouth. It's a common condition characterized by redness, cracking, and discomfort at the labial commissures (where the upper and lower lips meet).
The Fungal Culprit: Candida
When a fungal infection is present, it's most frequently caused by Candida species, a type of yeast. This makes it a candidal infection. Those experiencing angular cheilitis due to Candida may also have oral candidiasis, commonly known as thrush, inside their mouth.
Associated Causes
While fungal (candidal) infections are a common cause for angular cheilitis, it's important to note that the condition can also be linked to:
- Bacterial infections: Specifically, staphylococcal bacteria can be a contributing factor.
- Other underlying issues: Factors such as prolonged moisture, lip licking, nutritional deficiencies, or ill-fitting dentures can create an environment conducive to these infections.
Common Symptoms
Recognizing the signs of inflammation at the mouth corners can help in understanding the condition. The symptoms often include:
| Symptom | Description |
|---|---|
| Redness | Inflamed, irritated skin at the mouth corners |
| Cracking | Fissures, splits, or deep lines in the skin |
| Soreness | Discomfort or pain, especially when opening the mouth wide |
| Scaling | Dry, flaky skin patches |
Why Professional Diagnosis Matters
Identifying the exact cause of the inflammation, whether it's fungal, bacterial, or a combination, is crucial for effective treatment. A healthcare professional can accurately diagnose the condition and recommend the appropriate course of action, which may include antifungal or antibacterial treatments, or addressing underlying factors.
