What Is Thrush?
Thrush, or oral candidiasis (ICD-10 B37.0), is a yeast infection in the mouth. It appears as white, creamy patches on the tongue, cheeks, gums or roof of the mouth. While common in infants, it can affect anyone-especially those with a weakened immune system.
Common Causes and Risk Factors
- Antibiotic use, which disrupts the balance of mouth bacteria and yeast
- Weakened immunity from diabetes, illness or certain medical treatments
- Wearing dentures that aren't cleaned daily
- Dry mouth caused by medications or underlying health conditions
- Infants exposed via bottles, pacifiers or antibiotic courses
Signs and Symptoms
- White, creamy patches on the tongue, inner cheeks, gums or roof of the mouth
- Redness or soreness under and around the patches
- Pain or a burning sensation in the mouth
- Cracks or sores at the corners of the mouth
- Difficulty feeding or swallowing-most notable in babies
