Oral thrush, or candidiasis, is a common fungal infection affecting the mouth and throat. It occurs when the Candida Fungus overgrows in the oral cavity, leading to uncomfortable symptoms.

Symptoms of Oral Thrush

White patches: One of the hallmark symptoms of oral thrush is the presence of white, creamy, or curd-like patches on the tongue, inner cheeks, roof of the mouth, gums, or throat. These patches can be easily scraped off, revealing red and sometimes bleeding tissue underneath.
Soreness and discomfort: The affected areas may become sore, tender, or even painful, making it uncomfortable to eat or swallow. In severe cases, the discomfort can extend beyond the mouth to the throat, leading to difficulty speaking or swallowing.
Loss of taste: Oral thrush can affect the taste buds, resulting in a loss of taste or a persistent metallic taste in the mouth.
Dry mouth: Some individuals with oral thrush may experience dry mouth or increased thirst due to the fungal infection affecting the salivary glands.
Cracking and redness at the corners of the mouth: In some cases, oral thrush can cause cracking and redness at the corners of the mouth, known as angular cheilitis or angular stomatitis.

Causes of Oral Thrush

Candida overgrowth: Oral thrush is primarily caused by an overgrowth of the Candida fungus, specifically Candida albicans, which is naturally present in the mouth, digestive tract, and other body parts. Under normal circumstances, the immune system and beneficial bacteria in the mouth keep the growth of Candida in check. However, certain factors can disrupt this balance and lead to overgrowth, resulting in oral thrush.
Weakened immune system: A weakened immune system is a common risk factor for developing oral thrush. Conditions such as HIV/AIDS, diabetes, cancer, or undergoing chemotherapy or radiation therapy can impair the immune system’s ability to control Candida overgrowth.
Medications: Certain medications can increase the risk of oral thrush. Antibiotics, for example, can disrupt the natural balance of bacteria in the mouth, which may allow Candida to thrive. Corticosteroids, used to treat inflammatory conditions, and immunosuppressive drugs can also contribute to developing oral thrush.
Poor oral hygiene: Inadequate practices can create an environment conducive to Candida overgrowth. Failing to brush and floss regularly, not cleaning the tongue, or using oral products that contain harsh chemicals or alcohol can disrupt the natural balance in the mouth and increase the risk of oral thrush.
Dentures: Wearing ill-fitting or improperly cleaned dentures can contribute to the development of oral thrush. Dentures can create an environment where Candida accumulates and thrives if not cleaned thoroughly.
Dry mouth: Dry mouth, also known as xerostomia, can be caused by various factors such as medications, medical conditions, or breathing through the mouth. Reduced saliva flow can disrupt the natural defence mechanism against Candida, increasing the risk of oral thrush.
Other factors: Certain lifestyle factors such as smoking, excessive alcohol consumption, and poor nutrition can weaken the immune system and contribute to the development of oral thrush.

It’s important to note that while Candida overgrowth is the primary cause of oral thrush, it is essential to identify and address the underlying factors contributing to this overgrowth for effective treatment and prevention of recurrent episodes.

When should I see my doctor about oral thrush, and how is it diagnosed?

It is advisable to consult your doctor or dentist if you suspect you have oral thrush or if you experience persistent symptoms. They can provide a proper diagnosis and recommend appropriate treatment. Here are some indicators of when to seek medical attention for oral thrush:

Persistent symptoms: If you have tried home remedies or over-the-counter treatments for oral thrush, but the symptoms persist or worsen over time, it is recommended to see a healthcare professional.
Severe symptoms: If you experience severe discomfort, pain, difficulty swallowing, or speaking due to oral thrush, it is important to seek medical attention promptly.
Recurrent episodes: If you have a history of recurring oral thrush, it is advisable to consult your doctor or dentist for further evaluation and management. They can assess the underlying causes and recommend preventive measures to reduce the risk of recurrence.
Weakened immune system: If you have a weakened immune system due to conditions such as HIV/AIDS or diabetes or are undergoing immunosuppressive therapy, it is crucial to consult a healthcare professional to diagnose and treat oral thrush properly.

Diagnosing oral thrush typically involves a healthcare professional visually examining the oral cavity. They may scrape off a sample of the white patches using a sterile swab for laboratory analysis to confirm the presence of Candida fungus. In some cases, additional tests may be conducted to identify any underlying factors contributing to the infection. In that case, a dentist may refer you to a medical professional.

Remember, seeking medical advice from a healthcare professional is important for an accurate diagnosis and appropriate oral thrush treatment. They can provide personalized recommendations based on your situation and help manage the condition effectively.

Treatment Options for Oral Thrush

Antifungal medications: The primary treatment for oral thrush is antifungal medications, available in various forms such as oral rinses, lozenges, and topical creams. These medications eliminate the Candida fungus and restore a healthy balance in the mouth. Following the prescribed treatment regimen is important to eradicate the infection effectively.
Good oral hygiene: Proper oral hygiene is essential in managing and preventing oral thrush. Regularly brush your teeth with a soft toothbrush and fluoride toothpaste. Gently clean your tongue and remove any debris. Avoid mouthwashes that contain alcohol, as they can exacerbate the condition.
Address underlying factors: Oral thrush can sometimes result from underlying factors such as a weakened immune system, poorly controlled diabetes, or certain medications like antibiotics or corticosteroids. Treating or managing these underlying factors can help prevent the recurrence of oral thrush.
Dietary adjustments: In some cases, adjusting the diet can aid in managing oral thrush. Minimize the consumption of sugary foods and beverages, as they can contribute to the growth of Candida fungus. Increase the intake of probiotic-rich foods like yogurt, which can help restore a healthy balance of bacteria in the mouth.
Consult a healthcare professional: If the symptoms of oral thrush persist despite home remedies or over-the-counter treatments, it is advisable to consult a healthcare professional. They can thoroughly evaluate, identify underlying causes, and recommend appropriate treatment options.

Prevention of Oral Thrush

Preventing oral thrush involves maintaining good oral hygiene and implementing certain lifestyle practices. Here are some tips to help prevent oral thrush:

Practice proper oral hygiene: Brush your teeth at least twice daily using a soft toothbrush and fluoride toothpaste. Pay attention to brushing along the gumline and the surface of your tongue. Floss daily to remove plaque and debris from between your teeth.
Clean dentures thoroughly: If you wear dentures, ensure they are cleaned properly and regularly. Remove them at night and clean them with a denture cleanser recommended by your dentist. Make sure your dentures fit well to prevent the accumulation of Candida.
Avoid mouthwashes containing alcohol: Alcohol-based mouthwashes can disrupt the natural balance of bacteria in your mouth and promote Candida overgrowth. Opt for alcohol-free mouthwashes or rinse with saltwater instead.
Maintain a healthy lifestyle: Adopting a healthy lifestyle can help prevent oral thrush. This includes eating a balanced diet rich in fruits, vegetables, and whole grains while limiting sugary and processed foods. Stay hydrated and limit your alcohol consumption. Quit smoking or using tobacco products, as they can weaken the immune system and increase the risk of oral thrush.
Manage underlying health conditions: If you have an underlying health condition, such as diabetes or HIV/AIDS, work closely with your healthcare provider to manage the condition effectively. Keeping these conditions under control can help prevent oral thrush.
Be cautious with antibiotics: If you need to take antibiotics, discuss with your healthcare provider about possible preventive measures for oral thrush. They may recommend probiotic supplements or suggest specific oral hygiene practices during the treatment to minimize the risk of Candida overgrowth.
Regular dental check-ups: Visit your dentist for routine dental check-ups and cleans. Regular professional dental examinations help remove plaque and tartar buildup, reducing the chances of oral thrush development.

You can significantly reduce the risk of developing oral thrush by practising good oral hygiene, adopting a healthy lifestyle, and addressing underlying health conditions. If you notice any symptoms or have concerns, consult your dentist or healthcare provider for further guidance and appropriate preventive measures.
