Oral Thrush

Overview

Oral thrush is a condition in which the fungus Candida albicans accumulates on the lining of your mouth. It causes creamy white lesions usually on the tongue or inner cheeks. Oral thrush can occur in anyone, but it's more likely in babies, older adults, people with suppressed immune systems, or those taking certain medications. If you have a healthy immune system, oral thrush is typically a minor issue, but it can be more severe for those with weakened immune systems. Symptoms may include creamy white lesions, redness, burning, soreness, difficulty eating or swallowing, denture stomatitis, and loss of taste.

Understanding the disease

Symptoms

Symptoms of oral thrush in children and adults may include creamy white lesions on the tongue, inner cheeks, or roof of the mouth, slightly raised lesions with a cottage cheese-like appearance, redness, burning, or soreness, slight bleeding if the lesions are rubbed or scraped, cracking and redness at the corners of the mouth, a cottony feeling in the mouth, loss of taste, and redness, irritation, and pain under dentures. Infants may experience difficulty feeding or being fussy and irritable. If you or your child develops white lesions inside the mouth, it's important to consult a doctor or dentist.

Risk Factors

The risk factors for developing oral thrush include:

1. Weakened immunity: Oral thrush is more likely to occur in infants and older adults due to reduced immunity. Medical conditions and treatments that can suppress the immune system, such as cancer, organ transplantation, required immune-suppressing drugs, and HIV/AIDS can increase the risk.
2. Diabetes: When blood sugar levels are uncontrolled, it encourages the growth of candida.
3. Vaginal yeast infections: The same fungus that causes oral thrush can also cause vaginal yeast infections. Transmission from mother to baby can occur during birth or through breastfeeding.
4. Medications: Certain drugs, such as prednisone, inhaled corticosteroids, and certain antibiotics, can disturb the natural balance of microorganisms in your body, increasing the risk of oral thrush.
5. Other oral conditions: Wearing dentures, particularly upper dentures, or having conditions that cause dry mouth can increase the risk of oral thrush.

Development

Oral thrush is caused by an overgrowth of the fungus Candida albicans in the mouth. The fungus is normally present in the mouth, but under certain conditions, it can multiply excessively and cause symptoms. Risk factors that contribute to the development of oral thrush include a weakened immune system, diabetes, vaginal yeast infections, certain medications, and other oral conditions such as wearing dentures or having dry mouth. In healthy individuals, oral thrush is usually a minor issue, but for those with a weakened immune system, symptoms may be more severe and difficult to control.

Assessment and Diagnosis

Triage

You should see a doctor if oral thrush is suspected, especially if the symptoms are severe, persistent, or accompanied by other symptoms. Symptoms that warrant a doctor's visit include difficulty swallowing, severe pain or discomfort, bleeding, and a cottony feeling in the mouth. It's also important to consult a doctor if you or your child develops white lesions inside the mouth and you are unsure about the cause. In cases where oral thrush is suspected in an infant, it's crucial to consult a doctor for proper diagnosis and treatment, as the infection can affect feeding and cause discomfort. If the infant is breastfeeding and the mother has a nipple infection, both mother and baby should be evaluated by a doctor to manage the infection effectively.

Diagnosis

To diagnose oral thrush, your doctor or dentist may examine your mouth to look at the lesions, take a small scraping of the lesions to examine under a microscope, and perform a physical exam and certain blood tests to identify any possible underlying medical condition that may be the cause of oral thrush.

Management and Treatment

Complications

If left untreated, oral thrush can lead to more-serious systemic candida infections in people with weakened immune systems or certain health conditions. In such cases, thrush may spread to other parts of the body. For example, in people with HIV/AIDS, thrush can spread to the esophagus or other parts of the gastrointestinal tract, causing more severe infections. In severe cases, usually related to cancer or a weakened immune system from HIV/AIDS, the lesions may spread downward into your esophagus - the long, muscular tube stretching from the back of your mouth to your stomach (Candida esophagitis). If this occurs, you may experience difficulty swallowing and pain or feel as if food is getting stuck in your throat.

Prevention

There are several measures that can help reduce the risk of developing oral thrush:

1. Rinse your mouth: If you need to use a corticosteroid inhaler, be sure to rinse your mouth with water or brush your teeth after taking your medication.
2. Brush your teeth: Brush your teeth at least twice a day and floss daily or as often as your dentist recommends.
3. Check your dentures: Remove your dentures at night. Make sure dentures fit properly and don't cause irritation. Clean your dentures daily. Ask your dentist for the best way to clean your type of dentures.
4. Manage diabetes: If you have untreated diabetes or the disease isn't well-controlled, work with your healthcare provider to manage your condition effectively.
5. Practice good hygiene: Maintain good oral and personal hygiene to prevent the overgrowth of Candida fungus. Remember that oral thrush is more likely to occur in people with suppressed immune systems, certain health conditions, or those taking certain medications. If you have concerns or suspect you have oral thrush, consult your healthcare provider or dentist for appropriate evaluation and treatment.

Home Remedies

Home remedies for oral thrush may include:

1. Rinse your mouth with saltwater: Mix a half teaspoon of salt in a cup of warm water and swish it in your mouth several times a day. This can help relieve pain and reduce fungal growth.
2. Use a soft toothbrush: Avoid using a toothbrush with hard bristles, as it may cause irritation. Opt for a soft-bristled toothbrush and be gentle while brushing your teeth.
3. Practice good oral hygiene: Brush your teeth at least twice a day, floss daily, and use mouthwash to maintain good oral hygiene. This can help prevent the overgrowth of Candida fungus.
4. Gargle with a mixture of oil and vinegar: Mix equal parts of olive oil and apple cider vinegar and gargle with it for several seconds, then spit it out. This can help alleviate symptoms and reduce fungal growth.
5. Avoid using antibacterial mouthwashes: Antibacterial mouthwashes can disrupt the balance of bacteria in your mouth, allowing the Candida fungus to grow. Stick to a plain, alcohol-free mouthwash or use water to rinse your mouth.
6. Maintain proper denture care: If you wear dentures, remove them at night, clean them thoroughly every day, and ensure they fit properly to prevent irritation.
7. Avoid using flavored oral products: Flavored lip balms, toothpaste, and mouthwashes may encourage fungal growth. Stick to plain, unflavored products.
8. Eat yogurt or take probiotics: Consuming probiotic-rich yogurt or taking probiotic supplements can help restore the balance of bacteria in your mouth and reduce fungal growth. Please note that while these home remedies may provide some relief, they may not always be effective in treating oral thrush. If your symptoms persist or worsen, it's essential to consult a healthcare professional for proper diagnosis and treatment.

Treatment

Treatments for oral thrush include antifungal medications and addressing any underlying conditions or practices that may have contributed to the infection. For healthy individuals, oral thrush is often self-resolving and may not require treatment, especially if it's mild. However, if the infection is severe, causes discomfort, or if you have a weakened immune system, you may need medical treatment. Your doctor or dentist may prescribe an antifungal medication, usually in the form of lozenges, tablets, or liquid that you swish and swallow. Follow their instructions for use and complete the full course of treatment, even if your symptoms improve. Additionally, address any underlying risk factors or conditions, such as poor oral hygiene, dentures that don't fit properly, or a suppressed immune system.

Preparing for medical consultation

To prepare for an appointment for oral thrush, you can follow similar steps as mentioned above for the general mouth discomfort appointment preparation. Here's a summary of what you can do:

1. Ask if there's anything you need to do before the appointment, such as avoiding certain foods or rinses.
2. Make a list of your symptoms, including any that may seem unrelated to your oral discomfort.
3. Make a list of key personal information, including any major stresses or recent life changes.
4. Make a list of all medicines, vitamins, herbs, or other supplements that you're taking, including the doses.
5. Bring a copy of any medical or dental records, including test results, that are related to this problem.
6. Take a family member or friend with you, if possible, for support and to help you remember everything.
7. Prepare questions ahead of time to ask your health care provider or dentist. Some basic questions to ask include:
   • What's likely causing my symptoms?
   • What are other possible causes?
   • What kinds of tests do I need?
   • What's the best course of action?
   • Are there any restrictions that I need to follow?
   • Should I see a specialist?
   • Are there any printed materials or websites you can recommend? Prepare for your appointment by gathering relevant information and asking questions to ensure you receive the best possible care. Remember to tailor your questions and concerns to your specific situation.
