🍞 Oral Yeast Infection (Thrush): Causes, Symptoms & Treatment

Oral yeast infection, commonly known as oral thrush or oral candidiasis, is a fungal infection in the mouth caused by an overgrowth of Candida species, particularly Candida albicans. 

While Candida naturally resides in the oral cavity, certain factors can lead to its overgrowth, resulting in infection.

🧠 Causes of Oral Yeast Infection

Several factors can contribute to the development of oral thrush:

  • Weakened immune system 🛡️
    Conditions like HIV/AIDS, cancer treatments, or organ transplants can compromise immunity.
  • Diabetes 🍬
    High blood sugar levels can promote fungal growth.
  • Antibiotic use 💊
    Broad-spectrum antibiotics can disrupt the balance of microorganisms in the mouth.
  • Dentures 🦷
    Especially if ill-fitting or not cleaned properly.
  • Dry mouth 💧
    Reduced saliva flow can create an environment conducive to Candida overgrowth.
  • Smoking 🚬
    Tobacco use can increase the risk of oral infections.

🔍 Symptoms of Oral Thrush

Be alert for the following signs:

  • White, creamy lesions 🦠
    Often on the tongue, inner cheeks, roof of the mouth, gums, or tonsils.
  • Redness or soreness 🔴
    Especially under dentures or at the corners of the mouth.
  • Cracking and redness 😖
    At the corners of the mouth (angular cheilitis).
  • Loss of taste 👅
    Or a cottony feeling in the mouth.
  • Pain during eating or swallowing 🍽️
    Particularly if the infection spreads to the throat.

🧪 Diagnosis

Diagnosis typically involves:

  • Clinical examination 👨‍⚕️
    Visual inspection of the mouth for characteristic lesions.
  • Microscopic analysis 🔬
    Scraping of lesions examined under a microscope.
  • Culture tests 🧫
    To identify the specific Candida species involved.

💊 Treatment Options

Treatment depends on the severity and underlying causes:

  • Antifungal medications 💊
    Such as nystatin, clotrimazole, or fluconazole, administered orally or topically.
  • Addressing underlying conditions 🩺
    Managing diabetes or adjusting medications that may contribute to infection.
  • Proper denture care 🦷
    Cleaning and, if necessary, adjusting dentures to ensure proper fit.

🛡️ Prevention Tips

Reduce your risk of oral thrush with these practices:

  • Maintain good oral hygiene 🪥
    Brush twice daily and floss regularly.
  • Clean dentures daily 🧼
    Remove at night and soak in a denture-cleaning solution.
  • Limit sugar intake 🍭
    High-sugar diets can promote fungal growth.
  • Quit smoking 🚭
    Tobacco use increases the risk of oral infections.
  • Regular dental check-ups 🗓️
    Routine visits can help detect and manage early signs of infection.

❓ Frequently Asked Questions (FAQs)

Q: Is oral thrush contagious?
