Oral Thrush (Mouth Thrush)

Key Points

Overview

Oral thrush, also known as mouth thrush, is a common fungal infection caused by an overgrowth of Candida in the mouth. It's generally harmless and easily treatable with medication. While it can affect anyone, it is particularly common in infants and older adults who wear dentures. Certain health conditions or medications can also increase the risk. Oral thrush is typically managed with antifungal medications prescribed by a doctor, which help to control the fungal growth and relieve symptoms.
