A 10-year-old boy with asthma, taking inhaled fluticasone (Flovent), presents for treatment of avulsed teeth. His inhaled corticosteroid medication can predispose him to which oral condition?

Inhaled corticosteroids like fluticasone locally suppress mucosal immune defenses in the oropharynx, predisposing patients to oral candidiasis — this is why patients are advised to rinse their mouth with water (and spit, not swallow) after every use, and ideally use a spacer device to reduce oral deposition.
