Oral thrush treatment and safety
Oral thrush is an overgrowth of Candida yeast on mouth tissues that can cause removable white patches, soreness, altered taste, or burning.
What are the signs and causes of oral thrush?
Oral thrush is an overgrowth of Candida yeast on mouth tissues that can cause removable white patches, soreness, altered taste, or burning.
Why can Candida overgrow in the mouth?
Candida may live in the mouth without symptoms, but antibiotics, inhaled corticosteroids, dry mouth, dentures, diabetes, or reduced immunity can permit overgrowth. Other white lesions can look similar, so examination matters.
How should oral thrush be diagnosed and treated?
Arrange diagnosis before using an antifungal. Treatment may involve a prescribed topical or systemic medicine, plus denture cleaning, removing dentures at night when advised, rinsing after inhaled steroids, and addressing dry mouth or another trigger.
When do mouth patches need dental assessment?
Seek care for persistent or recurrent patches, bleeding, difficulty swallowing, fever, or poor general health. Prompt assessment is important for infants and people with reduced immunity.
What should you ask about suspected oral thrush?
Are the patches Candida or another lesion, what trigger is present, and do my dentures, inhaler, medicines, or medical conditions need review?
Frequently asked questions
Can symptoms alone confirm the cause?
No. Several dental conditions overlap, so diagnosis uses the history, examination, and imaging when indicated.
What treatment might be needed?
Arrange diagnosis before using an antifungal. Treatment may involve a prescribed topical or systemic medicine, plus denture cleaning, removing dentures at night when advised, rinsing after inhaled steroids, and addressing dry mouth or another trigger.
