Thrush (oral candidiasis) is a common yeast infection caused by the fungus Candida albicans. It affects the mouth and throat, producing white or yellowish patches that may be sore or inflamed. While anyone can develop thrush, infants, older adults, and people with weakened immune systems are most at risk.
Symptoms can vary by age but often include:
Thrush develops when Candida overgrows. Common triggers include:

With appropriate antifungal treatment, mild cases of oral thrush often clear within 7-14 days. More severe or persistent infections may require longer therapy and follow-up care.
While over-the-counter antifungal rinses or lozenges can help mild thrush, it's best to consult a healthcare provider for an accurate diagnosis and prescription-strength medication if needed.
Oral thrush itself isn't highly contagious, but the Candida yeast can spread through direct contact such as kissing or sharing utensils, especially among people with weakened immune systems.
Infants can acquire Candida albicans from the mother's birth canal or when breast milk alters the mouth's pH. Sterilizing bottles, pacifiers, and maintaining good oral hygiene reduces the risk.
In infants, thrush appears as creamy white or yellowish patches on the tongue, inner cheeks, or roof of the mouth. These patches resist gentle scraping and may cause feeding discomfort.
Some mild cases may resolve without treatment, but untreated thrush can worsen or spread to other areas. Medical intervention ensures quicker relief and prevents complications.
Reducing sugar, refined carbohydrates, and yeast-containing foods can help control Candida overgrowth. Incorporating probiotics and a balanced diet supports healthy oral flora.
Yes-most antifungal treatments are safe during breastfeeding. Treating both mother and baby simultaneously and using prescribed topical creams or oral medications helps prevent reinfection.
Recurrence is possible if underlying factors like antibiotic use, diabetes, or immune suppression remain unaddressed. Managing these risk factors lowers the chance of thrush returning.
The ICD-10 code for oral thrush is B37.0, which healthcare providers use for accurate diagnosis documentation and insurance billing purposes.
