Oral thrush is an overgrowth of Candida, a yeast that normally lives in small amounts in the mouth. When the balance shifts, it can coat the tongue, cheeks and throat.
Thrush is common in babies, older adults, denture wearers and people taking antibiotics or inhaled steroids. In healthy adults without an obvious trigger, it can be a sign of an underlying condition worth checking.

- Creamy white patches on the tongue, inner cheeks or roof of the mouth
- Redness or soreness, sometimes bleeding if patches are scraped
- A cottony feeling in the mouth
