Some of the common cures for treating a white tongue caused by oral thrush include eating yogurt and taking lozenges, tablets or liquid antifungals. Leukoplakia is common among smokers and also causes a white tongue. A common cure for this is to stop smoking, notes MedicineNet.
A removable layer of food debris or bacterial plaque can cause a white tongue. Other common causes include oral thrush or candidiasis, leukoplakia or hairy leukoplakia, notes MedicineNet.
Candidiasis is a yeast infection that develops inside the mouth. It is more likely to occur after patients take antibiotics that may kill good bacteria in the mouth. Patients should eat plain yogurt with active, live cultures to restore the proper fauna in their mouths. In addition to this, doctors may prescribe medication to fight the infection, states WebMD.
Leukoplakia is related to chronic irritation in the mouth and causes white patches that cannot be scraped off. It is most often caused by tobacco use. Leukoplakia is usually benign, but it can be a precursor to cancer, and doctors sometimes recommend a biopsy, explains MedicineNet.
Hairy leukoplakia is a rough, white patch on the side of the tongue caused by the Epstein-Barr virus. It is common in individuals who have compromised immune systems. Doctors may use antiviral medications to treat hairy leukoplakia, states MedicineNet.
