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 Candida’s growth 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?
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.
Below 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 essential 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 vital for an accurate diagnosis and appropriate oral thrush treatment. They can provide personalised recommendations based on your situation and help manage the condition effectively.
Treatment Options for Oral Thrush
Antifungal medications
Antifungal medications, available in various forms such as oral rinses, lozenges, and topical creams, are the primary treatment for oral thrush.
These medications eliminate the Candida fungus and restore a healthy balance in the mouth. Following the prescribed treatment regimen is essential to eradicate the infection effectively.
Good oral hygiene
Proper oral hygiene is essential in managing and preventing oral thrush. Brush your teeth regularly 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 help manage oral thrush. Minimise 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 the condition, 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 regularly and adequately. 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 antibiotics, discuss possible preventive measures for oral thrush with your healthcare provider. They may recommend probiotic supplements or suggest specific oral hygiene practices during the treatment to minimise 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.
Summary
Oral thrush is a common fungal infection that can cause discomfort and affect oral health. Recognising the symptoms, such as white patches, soreness, and loss of taste, is crucial for early diagnosis and treatment.
Antifungal medications, good oral hygiene practices, and addressing underlying factors can effectively manage and resolve oral thrush.
If you suspect you have oral thrush or your symptoms persist, seek professional guidance from a healthcare provider or the nearest dentist to receive a diagnosis, appropriate treatment, or medical specialist referral and prevent further complications.
