Rinsing the mouth several times a day with warm salt water is an effective home treatment for thrush, according to WebMD. Gentian violet, which is available without a prescription, can also be effective. This natural dye works by killing bacteria and fungi in the mouth.
Patients can also minimize the symptoms of thrush at home by drinking cold liquids or eating frozen ice treats and sticking with soft foods that are easy to swallow, such as pudding, applesauce and ice cream, explains WebMD. If the white patches caused by thrush are painful, using a straw to drink can minimize contact with the mouth.
