What Are the Treatment Options for Thrush in Adults?

Doctors treat oral thrush with an antifungal medication that is administered in the form of lozenges, tablets or mouthwash. Oral thrush occurs when the fungus Candida albicans, which normally lives in the mouth, grows out of control, causing candidiasis. Oral thrush's symptoms include white lesions on the tongue and inner cheeks. These lesions can spread to the tongue, tonsils, roof of the mouth and back of the throat, explains Mayo Clinic.

Candida albicans is a yeast that normally lives in the human body, but certain conditions cause it to grow out of control, especially in the mouth or genitals. Oral thrush is the common name for candidiasis of the mouth, while the common name for genital candidiasis is a yeast infection. Doctors treat genital candidiasis similarly to oral candidiasis, with an oral tablet, topical cream or a suppository, according to WebMD.

A weak immune system or antibiotics that kill certain bacteria can cause candidiasis to develop. Specific risk factors for oral candidiasis include wearing dentures, having conditions that cause dry mouth, and taking certain oral or inhaled medications. To decrease the risk of oral candidiasis, individuals can rinse their mouths after using devices like corticosteroid inhalers, brush and floss daily, see the dentist regularly, clean their dentures, and limit their intake of foods high in yeast and sugar, notes Mayo Clinic.
