Oral Thrush

10 min read

Oral thrush, also known as oropharyngeal candidiasis, is a fungal infection of the mouth caused by the yeast Candida albicans. It is a common condition, especially in infants and young children, and can also affect adults. It is characterized by white patches on the tongue, inner cheeks, and sometimes the roof of the mouth.

Causes of Oral Thrush

Oral thrush is caused by an overgrowth of the yeast Candida albicans. This yeast is normally present in the mouth, but when certain conditions occur, it can multiply and cause an infection. These conditions include:

  • A weakened immune system
  • Certain medications, such as antibiotics and corticosteroids
  • Diabetes
  • Smoking
  • Dry mouth

Diagnosis of Oral Thrush

Oral thrush is usually diagnosed based on the appearance of the lesions. Your doctor may also take a swab of the lesions to test for the presence of the yeast. In some cases, a blood test may be necessary to confirm the diagnosis.

Complications of Oral Thrush

In some cases, oral thrush can spread to other parts of the body, such as the esophagus, lungs, or skin. This can lead to more serious complications, such as pneumonia or systemic candidiasis. In people with weakened immune systems, oral thrush can spread to the blood and cause a potentially life-threatening infection.

Causes

Risk Factors for Oral Thrush

  • Weakened immune system: People with weakened immune systems, such as those with HIV/AIDS, are more likely to develop oral thrush.
  • Antibiotics: Antibiotics can disrupt the balance of bacteria in the mouth, allowing Candida to overgrow.
  • Dry mouth: Saliva helps to keep the mouth moist and free of bacteria. People with dry mouth are more likely to develop oral thrush.

Getting a Diagnosis

Signs and Symptoms of Oral Thrush

The most common symptom of oral thrush is white patches on the tongue, inner cheeks, and sometimes the roof of the mouth. These patches may be painful and may bleed if scraped. Other symptoms include redness, soreness, and difficulty swallowing. In infants, oral thrush may cause a diaper rash.

Diagnostic Tests for Oral Thrush

A doctor or dentist can usually diagnose oral thrush by examining the mouth and looking for the characteristic white patches. In some cases, a sample of the affected tissue may be taken and sent to a laboratory for testing. This is done to confirm the diagnosis and to rule out other conditions, such as leukoplakia or lichen planus.

Treatment for Oral Thrush

Treatment for oral thrush usually involves antifungal medications, such as nystatin or clotrimazole. These medications are available in the form of lozenges, tablets, or liquid suspensions. In some cases, a doctor may prescribe an antifungal cream or ointment to be applied directly to the affected area. In infants, the doctor may recommend a topical antifungal cream or ointment.

Preventing Oral Thrush

The best way to prevent oral thrush is to practice good oral hygiene. This includes brushing your teeth twice a day, flossing daily, and using a mouthwash. It is also important to avoid sharing eating utensils, toothbrushes, and other items that may come into contact with saliva. If you are taking antibiotics, it is important to take probiotics to help restore the balance of bacteria in the mouth.
