Oral thrush is also known as:
- Oral Candidiasis
- Candidiasis of the mouth
- Moniliasis
- Yeast infection of the mouth
1.2. How Common is Oral Thrush?
Oral thrush is relatively common, particularly in infants, young children, older adults, and individuals with weakened immune systems. According to the Centers for Disease Control and Prevention (CDC), oral thrush is one of the most common fungal infections in humans. While it can affect people of all ages, certain populations are more susceptible.
1.3. Who is Most Likely to Get Oral Thrush?
Individuals at higher risk of developing oral thrush include:
- Infants: Their immune systems are still developing.
- Older adults: Their immune systems may be weakened.
- People with weakened immune systems: Such as those with HIV/AIDS, cancer, or undergoing chemotherapy or radiation therapy.

- People taking certain medications: Such as antibiotics or corticosteroids.
- People who wear dentures: Especially if they are not properly cleaned.
1.4. What Part of the Body Does Oral Thrush Affect?
Oral thrush primarily affects the mouth, including:
- Tongue
- Inner cheeks
- Gums
- Roof of the mouth
- Tonsils
- Throat (in severe cases)
2. Symptoms of Oral Thrush: Recognizing the Signs
Recognizing the symptoms of oral thrush is the first step toward seeking appropriate treatment. Symptoms can vary in severity and may differ between children and adults.
2.1. What are the Common Symptoms of Oral Thrush in Adults?
Common symptoms of oral thrush in adults include:
- Creamy white patches or spots on the tongue, inner cheeks, gums, or roof of the mouth.
- Slightly raised lesions that may resemble cottage cheese.
- Redness, burning, or soreness in the mouth.
- Difficulty eating or swallowing.
- Bleeding when the patches are scraped.
- Cracking and redness at the corners of the mouth (angular cheilitis).
- A cottony feeling in the mouth.
- Loss of taste.
2.2. What are the Symptoms of Oral Thrush in Babies?
In babies, symptoms of oral thrush may include:
- White patches on the tongue, inner cheeks, or gums.
- Difficulty feeding or irritability.
- Refusal to nurse or take a bottle.
- Passing the infection to the mother during breastfeeding.
2.3. How Does Oral Thrush Affect Breastfeeding Mothers?

3. Causes of Oral Thrush: Identifying the Root Factors
Understanding the causes of oral thrush can help individuals take preventive measures and manage their risk.
3.1. What Causes Oral Thrush?
Oral thrush is caused by an overgrowth of the Candida albicans fungus. This overgrowth can occur when the balance of microorganisms in the mouth is disrupted.
3.2. How Does Candida Albicans Cause Oral Thrush?
Candida albicans is a type of yeast that is naturally present in the mouth, digestive tract, and skin. Under normal circumstances, it does not cause any harm. However, when the immune system is weakened or the balance of microorganisms is disrupted, Candida can multiply and cause an infection.
