Oral Thrush Causes, Symptoms, Diagnosis and Treatment

What is Oral Thrush?

Oral thrush is candidiasis that occurs in the mouth. That is, oral candidiasis is a mycosis (yeast/fungal infection) of Candida species on the mucous membranes of the mouth.

Oral thrush causes creamy white lesions, usually on one’s tongue or inner cheeks.

Sometimes oral thrush may spread to the roof of the mouth, the gums or tonsils, or the back of the throat.

Causes of Oral Thrush:

Small amounts of the candida fungus are present in the mouth, digestive tract, and skin of most healthy people. They are normally kept in check by other bacteria and microorganisms in the body.

However, certain illnesses, stress, or medications can disturb the delicate balance, causing the fungus candida to grow out of control and causing thrush.

Medications that upset the balance of microorganisms in the mouth and may cause thrush include:

  • Corticosteroids
  • Antibiotics
  • Birth control pills

Illnesses or medical situations that make candida infection more likely include:
