The short answer
Oral candidiasis is an overgrowth of Candida yeast on the mouth lining, often causing removable white patches, soreness, or burning and requiring an examination for confirmation.
Why can Candida multiply in the mouth?
Candida can live in the mouth without symptoms, but antibiotics, inhaled steroid residue, dry mouth, dentures, diabetes, or reduced immune function can allow it to multiply. White material that wipes away may leave a red surface, while other white lesions do not wipe away.
How can you help prevent oral candidiasis returning?
Follow the prescribed antifungal plan, rinse and spit after inhaled corticosteroids, clean dentures as directed, and remove them at night if your dental professional advises it. Do not share medicines or assume every white patch is thrush.
When do oral candidiasis symptoms need dental care?
Seek care when patches are painful, swallowing is difficult, symptoms recur, or the person has immune suppression, uncontrolled diabetes, or a very young or frail age. A persistent non-wipeable patch needs assessment.
What should you ask about recurring oral candidiasis?
Ask whether the appearance is consistent with candidiasis and what may be allowing it to recur. Ask how to use the antifungal medicine, clean appliances, and review dry mouth or inhaler factors.
