Oral fungi are microorganisms living with the human cells and bacteria existing on the mouth. These organisms are called candida fungus, also known as yeast. Candidainfection is not limited to the mouth; it can occur in other parts of the body.
What Causes Thrush?
Small amounts of the candida fungus are present in the mouth, digestive tract, and skin of most healthy people and 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, causing thrush.
Medications that upset the balance of microorganisms in the mouth and may cause thrush include
Illnesses or medical situations that make candida infection more likely to develop include
People who smoke or wear dentures that don't fit properly also are at increased risk for thrush. In addition, babies can pass the infection to their mothers during breast-feeding.
What Are the Symptoms of Thrush?
Thrush usually develops suddenly, but it may become chronic, persisting over a long period of time. A common sign of thrush is the presence of creamy white, slightly raised lesions in your mouth - usually on your tongue or inner cheeks - but also sometimes on the roof of your mouth, gums, tonsils, or back of your throat. The lesions, which may have a "cottage cheese" appearance, can be painful and may bleed slightly when you scrape them or brush your teeth. In severe cases, the lesions may spread into your esophagus, or swallowing tube, causing:
Thrush can spread to other parts of the body, including the lungs, liver, and skin. This happens more often in people with cancer, HIV, or other conditions that weaken the immune system.
How Is Thrush Diagnosed?
*in case of oral infection :
Your dentist can diagnose thrush by examining your mouth. He or she looks for the distinctive white lesions on your mouth, tongue, or cheeks. Lightly brushing the lesions away reveals a reddened, tender area that may bleed slightly. A microscopic examination of tissue from a lesion can confirm the diagnosis.
*in case of esophagus infection :
Thrush that extends into your esophagus may require other tests to make the diagnosis. Such tests might include taking a throat culture (swabbing the back of your throat with sterile cotton and studying the microorganisms under a microscope), performing an endoscopy of your esophagus, stomach, and small intestine (examining the lining of these body areas with a lighted camera mounted on the tip of a tube passed through these areas), or taking X-rays of your esophagus.
How Is Thrush Treated?
Antifungal medications, which are generally taken for 10 to 14 days, are often prescribed to treat thrush. These medicines are available in tablets, lozenges, or liquids. Your dentist will have a specific treatment approach designed for you based on your age and the cause of the infection. Because the presence of candida infection can be a symptom of other medical problems, your dentist may suggest you seek care from a medical doctor as well so that any underlying health problems you may have can be treated.
