Treatment of tongue fungus involves the use of antifungal medications, which are available in liquid, tablets or lozenges, states WebMD. Dentists recommend proper dental hygiene to prevent fungal infections. A good example of a tongue fungus is oral thrush, which causes distinctive white lesions on the tongue, cheeks or mouth.
Antifungal medications are effective in treating fungal infections in healthy children and adults, but those with a weak immune system may have a slow response to medication, says WebMD. Patients take the medications for 10 to 14 days depending on an individual's condition and age. The dentist may refer patients with a fungal infection to a medical doctor because it can be a symptom of an underlying condition.
