Oral thrush overview
Oral thrush is a yeast infection that causes removable white patches, soreness, or burning in the mouth and needs cause-based care.
The short answer
Oral thrush is an overgrowth of Candida yeast on the mouth’s lining, causing creamy white patches, soreness, or a burning feeling. The patches may wipe away and leave a red, tender surface, although not every white patch is thrush.
What does suspected thrush mean inside the mouth?
The question describes a possible fungal infection of the tongue, cheeks, palate, or other oral tissues. It can follow antibiotics, inhaled steroid use, a dry mouth, dentures, or reduced immune protection, but a clinician must distinguish it from trauma, leukoplakia, and other white lesions.
How can you care for your mouth during suspected thrush?
Gently brush the teeth and tongue, clean dentures as directed, rinse after an inhaled steroid, and avoid smoking while the mouth is irritated. A dentist or doctor can inspect the tissue and prescribe an antifungal treatment when the findings fit thrush, while also addressing dryness, medication effects, or an underlying illness.
When should persistent white patches be examined?
Arrange an examination if white patches persist, recur, bleed when disturbed, or make eating and swallowing painful. Seek urgent medical help for difficulty swallowing, breathing trouble, dehydration, or rapidly worsening symptoms.
What should you ask about possible oral thrush?
Ask whether the appearance is consistent with thrush, whether a swab or other test is needed, and which medicines or health conditions may be contributing. Also ask how to use any antifungal medicine and what should happen if the patches return.
Frequently asked questions
Can oral thrush come back?
Yes. Recurrence can reflect continuing dryness, medicines, denture hygiene problems, or an underlying health issue, so the cause should be reviewed.
Can I scrape oral thrush off?
Some patches wipe away, but scraping can injure the underlying mucosa and does not treat the yeast overgrowth.
