What is oral thrush?
Oral thrush, also known as oral candidiasis, is a common fungal infection caused by the fungus Candida albicans. This fungus naturally exists in the mouth, skin, and intestines of healthy individuals, but when the natural microbial balance in the mouth is disrupted, its excessive growth leads to the development of thrush.
A prominent feature of oral thrush is the presence of white patches or coating on the tongue, gums, the roof of the mouth, or the inside of the cheeks, which is sometimes accompanied by burning, pain, a bitter taste, or a dry sensation in the mouth. In severe cases, even swallowing food or drinking liquids can cause pain and discomfort.
Although oral thrush usually appears to be a superficial problem, it can be a sign of a weakened immune system, prolonged antibiotic use, or underlying health conditions. For this reason, early detection and proper treatment are very important to prevent more serious complications and to maintain oral health.

What are the symptoms of oral thrush?
Timely diagnosis of oral thrush is the first step for quick and effective treatment. This fungal infection comes with a set of identifiable symptoms that can significantly affect an individual’s experience.
- White patches or coating
One of the most distinctive signs of oral thrush is the presence of creamy white patches or coating on the tongue, gums, the roof of the mouth, or the inside of the cheeks. These patches may be smooth or slightly raised, and when scraped, they can sometimes reveal a red and inflamed surface underneath. - Burning and mouth pain
Affected individuals often experience a burning sensation, pain, or tenderness in the areas impacted by the fungus. This discomfort can intensify when eating spicy or sour foods or drinking warm liquids. - Bitter taste or altered mouth taste
Oral thrush may cause a bitter or unusual taste in the mouth, affecting the eating experience and sometimes leading to a decreased appetite. - Dryness and oral inflammation
The fungus causes inflammation of the gums and oral mucosa, and in some cases, individuals may experience a dry mouth or minor bleeding when brushing their teeth. - Severe or chronic symptoms
In advanced cases or in individuals with a weakened immune system, the patches may spread, cause intense pain, and even interfere with swallowing food or drinking liquids.
Can oral thrush cause fever?
Oral thrush is usually a superficial fungal infection and, in most healthy individuals, does not cause fever. The infection is primarily limited to the oral mucosa and tongue, with symptoms including white patches, burning, pain, and altered taste, but it is not systemic.
However, in people with weakened immune systems—such as those with HIV, undergoing chemotherapy, or on long-term immunosuppressive medications—Candida can spread beyond the mouth and cause systemic infections, which may include fever and other general symptoms. Therefore, if someone experiences fever, general weakness, or other severe symptoms along with oral thrush, they should promptly see a doctor or dentist for proper evaluation and treatment.
What causes oral thrush?
Oral thrush usually occurs due to the overgrowth of the fungus Candida albicans in the mouth, a fungus that naturally exists in the human mouth, skin, and intestines. Under normal conditions, the population of this fungus is controlled by the immune system and the oral microbiome, but when this balance is disrupted, abnormal fungal growth leads to the development of thrush.
Several factors can disrupt this balance. Prolonged use of antibiotics, which reduce the beneficial bacteria in the mouth, is one of the most common causes. A weakened immune system due to conditions such as diabetes, HIV, or chemotherapy, the use of immunosuppressive medications, dry mouth, long-term use of dental prostheses, and even poor nutrition can all create conditions that promote excessive fungal growth.
How is oral thrush transmitted?
Although oral thrush is a common fungal infection, it usually does not spread through direct contact or from person to person except under certain conditions. Candida albicans, the main cause of thrush, naturally exists in the bodies of many people, and the disease occurs when the microbial balance and immune system are disrupted. However, in specific cases, transmission of thrush is possible.
Sharing oral items such as toothbrushes, straws, or spoons can provide a way for the fungus to enter another person’s mouth, especially if the recipient has a weakened immune system. Direct mouth-to-mouth contact can also transmit the fungus, particularly in infants or individuals with compromised immunity. Additionally, transmission from mother to infant during breastfeeding or through contaminated dental prostheses is another recognized route.
How is oral thrush diagnosed?
Accurate diagnosis of oral thrush is particularly important to enable effective treatment and prevent the infection from progressing. A dentist or doctor typically uses the following methods for diagnosis:
Clinical examination
The most basic and common method for diagnosing oral thrush is a direct oral examination. The dentist checks for white patches or creamy coating on the tongue, gums, the roof of the mouth, and the inside of the cheeks. Gently touching or scraping these patches can reveal the red and inflamed surface underneath, which is a classic sign of fungal infection.
Microscopic examination and fungal culture
In cases where the clinical diagnosis is not definitive or the infection is chronic, a sample of the white patch is taken and examined under a microscope to confirm the presence of Candida albicans. Additionally, culturing the fungus on specialized media can identify the type of fungus and the extent of its growth, helping in selecting the appropriate medication.
Evaluation of underlying factors
A complete diagnosis includes evaluating underlying conditions such as immune system status, chronic diseases (like diabetes), or the use of specific medications. This assessment helps the dentist identify the cause of oral thrush and provide comprehensive and preventive treatment.
Treatment of oral and dental fungal infections
Treatment of throat fungus, and more broadly of oral fungal infections, usually varies depending on the severity of the infection and the patient’s symptoms. Common treatments include the use of oral antifungal medications and maintaining good oral hygiene, such as regular brushing, flossing, and rinsing the mouth with salt water, which can help reduce the number of fungi and prevent the infection from recurring. Below, we will review the different treatment methods in detail.
Topical antifungal medications
- These medications are prescribed as mouthwash, lozenges, or ointments.
- Common topical antifungal medications include nystatin, miconazole, and clotrimazole.
Oral antifungal medications
- These are prescribed for individuals with severe or recurrent oral thrush.
- Common oral antifungal medications include fluconazole and itraconazole.
Home remedies
- Some home remedies that may help relieve the symptoms of oral thrush include:
- Salt water: Mix ½ teaspoon of salt in 1 cup of warm water and rinse your mouth several times a day.
- Yogurt: Yogurt contains probiotics that can help fight Candida fungus. Consume a tablespoon of yogurt several times a day or apply it to your mouth, leave it for 10–15 minutes, and then rinse.
- Coconut oil: Coconut oil has antifungal properties. Swish 1 tablespoon of coconut oil in your mouth, hold it for 10–15 minutes before swallowing, and then spit it out.
Conclusion
Oral thrush, or candidiasis, is a common fungal infection in the mouth characterized by white patches, burning, pain, and altered taste. While it is usually superficial and treatable in healthy individuals, it can be more severe in those with weakened immune systems and may require specialized treatment. Recognizing the symptoms, causes, and risk factors, maintaining proper oral hygiene, and timely diagnosis are key to successful treatment and preventing recurrence. Treatment methods include antifungal medications, lifestyle adjustments, and daily oral care, all of which help achieve quick recovery and maintain oral health.
