Oral thrush (also known as “oral candidiasis”) is a condition in which the fungus Candida albicans accumulates in your mouth. It appears as white lesions, commonly on the tongue and inner cheeks. Although Candida is normally found within the mouth, thrush is when it will overgrow and cause symptoms. People may notice a burning or soreness that can cause difficulty eating or swallowing. It is more likely to happen in babies and older adults due to decreased immunity. Risk factors include weakened immunity, diabetes, medications, dentures, and dry mouth. An anti-fungal medication will most likely be prescribed for thrush. However, recurrence can occur if the underlying cause is not addressed.
