What is Oral Thrush?

Oral thrush—also called oral candidiasis—is a common fungal infection caused by an overgrowth of Candida albicans. This yeast is normally present in the mouth, digestive tract, and skin, but under certain conditions, it can grow out of control and cause visible symptoms. While commonly associated with infants, oral thrush can affect people of all ages, especially those with weakened immune systems or underlying health conditions.

Causes and Risk Factors of Oral Thrush

Oral thrush is most common in babies, older adults, and people with compromised immune systems. It may also result from changes in the mouth’s microbiome or the use of certain medications. Risk factors include:

• Diabetes

• HIV/AIDS

• Cancer or chemotherapy

• Antibiotics, steroids, or birth control pills

• Poor-fitting dentures

• Smoking

• Dry mouth

• Pregnancy-related hormonal shifts

• High stress or weakened immunity

Symptoms of Oral Thrush

Symptoms of oral thrush include:

• White patches or sores on the tongue, inner cheeks, gums, or tonsils

• Pain or burning in the mouth

• Loss of taste or cottony feeling

• Cracking at the corners of the mouth

• In severe cases, the infection may spread to the esophagus

In breastfeeding infants, oral thrush can also be passed to the mother’s nipples, causing soreness, redness, or discomfort during nursing.

Treatment Options for Oral Thrush

If you or your child is showing signs of oral thrush, it’s important to see a doctor or dentist. Oral antifungal medications are typically prescribed. For babies, thrush usually clears on its own within 1–2 weeks, but if symptoms persist, schedule a pediatric visit. Adults should seek treatment promptly to rule out underlying health issues and prevent spread.
