Oral Thrush (Mouth Thrush): Causes, Symptoms, and Treatment
Oral thrush is also known as mouth thrush or Oral Candidiasis. It is a fungal infection that can affect people of all ages. It’s caused by an overgrowth of yeast, specifically Candida albicans, which is naturally present in our mouths. It is not usually a severe condition. However, it can still be uncomfortable. If not treated, it may lead to more serious oral health issues. So, what is oral thrush exactly, and how can you treat it? Let’s dive in!
What Is Oral Thrush?
Simply put, oral thrush is a fungal infection that results in white patches inside the mouth. These patches resemble cottage cheese. They can show up on the tongue, inner cheeks, gums, and the roof of the mouth. In healthy individuals, Candida yeast doesn’t cause any problems. However, it can grow out of control for various reasons. This overgrowth leads to an infection.
You might have heard of it in infants, but adults can get oral thrush too. It’s especially common in people with weakened immune systems. It also occurs in those taking medications that affect the body’s natural balance of bacteria and fungi.

Causes of Oral Thrush
There are several reasons why Candida might overgrow and lead to oral thrush. Some of the most common factors include:
- Weakened Immune System: Conditions like HIV/AIDS, cancer, or diabetes can reduce the body’s ability to fight off infections, making it easier for the yeast to spread.
- Antibiotics: These medications can disrupt the balance of bacteria in your mouth, wiping out the good bacteria that keep Candida in check.
- Corticosteroids: If you use inhalers for asthma, they can increase the risk of thrush by promoting yeast growth in the mouth.
- Diabetes: Uncontrolled blood sugar levels provide a nice food source for the yeast, making it easier for it to thrive.
- Poor Oral Hygiene: Not brushing and flossing regularly can cause food particles and bacteria to accumulate, providing a breeding ground for yeast. For a complete guide on proper brushing and flossing, visit our oral hygiene guide.
- Dentures: Wearing dentures that don’t fit well or aren’t cleaned properly can contribute to the development of thrush.
Symptoms of Oral Thrush
So, how do you know if you’ve got oral thrush? Here are the most common symptoms:
- White Patches: These creamy white lesions are typically found on the tongue, inner cheeks, or gums.
- Soreness or Sensitivity: The affected areas may feel sore, particularly when eating certain foods, like spicy or acidic items.
- Redness or Inflammation: The tissues under the white patches may become inflamed and irritated.
- Dry Mouth: You may feel like your mouth is dry or have a cotton-like feeling in your mouth.
- Cracks at the Corners of Your Mouth: This is a telltale sign of irritation from the infection.
- Difficulty Swallowing: If the infection spreads to your throat, it may make swallowing painful or uncomfortable.
If you’re experiencing symptoms of oral thrush, consult oral health professional for a diagnosis and treatment plan.
How Is Oral Thrush Diagnosed?
A dentist or doctor can easily diagnose oral thrush by looking at the white patches in your mouth. If the condition seems complicated or persistent, they may perform a swab test to confirm the diagnosis or rule out other conditions.
Treatment for Oral Thrush
The good news is that oral thrush is treatable. Depending on how severe the infection is, your dentist or doctor might recommend:
- Antifungal Medications: The most common treatment is antifungal drugs, such as nystatin or fluconazole. These can be prescribed as lozenges, liquid solutions, or oral tablets.
- Topical Antifungal Treatments: For mild cases, topical treatments might be applied directly to the affected areas.
- Managing Underlying Conditions: For individuals with diabetes or other conditions that make them more susceptible to thrush, controlling the underlying health issue is key.
- Probiotics: Taking probiotics may help restore the balance of good bacteria in your mouth, which can reduce the risk of future thrush outbreaks.
Home Remedies for Oral Thrush
While it’s essential to follow your doctor’s or dentist’s advice, there are a few home remedies that might help ease the discomfort of oral thrush:
- Saltwater Rinse: Gargling with warm salt water can reduce swelling and soothe irritated areas.
- Coconut Oil: Swishing coconut oil in your mouth (a practice called oil pulling) may help fight off the infection naturally.
- Baking Soda: Using baking soda as a mouth rinse can help balance yeast levels in the mouth.
Keep in mind, these remedies can provide some relief, but they shouldn’t replace antifungal treatment from a healthcare professional.
Preventing Oral Thrush
Preventing oral thrush boils down to maintaining good oral hygiene and being mindful of certain habits. Here are a few tips to reduce your risk:
- Brush and Floss Regularly: Brush your teeth at least twice a day and floss once a day to remove food particles and bacteria that can lead to thrush. For tips on effective brushing and flossing techniques, visit our oral hygiene tips.
- Clean Your Dentures: If you wear dentures, be sure to clean them daily and remove them at night to give your mouth a chance to rest.
- Limit Sugar Intake: Since yeast feeds on sugar, cutting back on sugary foods can help prevent thrush.
- Rinse After Inhalers: If you use a corticosteroid inhaler, make sure to rinse your mouth afterward to avoid yeast buildup.
- Manage Diabetes: Keep your blood sugar levels in check to reduce the risk of thrush and other oral health issues. Learn more about managing diabetes and oral health on our diabetes and oral care page.
