Thrush is diagnosed by the dentist after examining the mouth, this is normally just a visual oral examination, because of the tell tale signs of the yeast infection. The white inflamed lesions are normally enough for a diagnosis of thrush.
The dental professional will normally take a light brushing of the tongue or cheek lesions and under a microscopic examination the tissues can confirm the diagnosis. If the dentist feels that the yeast infection might have spread to the esophagus other test might be done to arrive at the diagnosis.
These tests could include a throat swab on the back of the throat, which the cotton on the swab will be studied under a microscope to confirm esophagus thrush. |
