Thrush is a common mouth infection in infants. It is caused by yeast called Candida albicans. Candida is often found in babies’ mouths without causing any problems. But because their immune systems are still developing, sometimes the amount of yeast can overgrow and lead to an infection. Typical symptoms are white, cheesy, or curd-like patches in the mouth. These patches can be wiped off but may lead to minor bleeding, pain, and redness in the mouth. Diagnosis is based on an examination of the mouth. The infection often goes away after treatment with antifungal medication.
