What is the condition known as candidiasis in the mouth, particularly in children?

Candidiasis in the mouth, particularly in children, is known as oral thrush. This condition is caused by an overgrowth of the Candida yeast, which is a type of fungus that normally exists in small amounts in the mouth. In infants and young children, their immune systems are still developing, making them more susceptible to this type of infection.

Oral thrush presents as white patches on the tongue, inner cheeks, and sometimes the gums and tonsils. These patches may resemble cottage cheese and can be painful, leading to difficulty eating or swallowing. It's essential to diagnose and treat oral thrush promptly to prevent further discomfort and complications.

The other conditions listed have different characteristics and causes. Angular cheilitis affects the corners of the mouth and is usually associated with cracks or sores, often due to a fungal or bacterial infection. Canker sores are painful ulcers that can occur in the mouth but are not related to fungal infections. Oral herpes, caused by the herpes simplex virus, manifests as cold sores or blisters around the mouth and is distinct from candidiasis. Understanding these differences helps in identifying and treating oral conditions appropriately.
