Oral Thrush (Candida Infection): Causes, Symptoms and Treatment
If you or your baby have noticed creamy white patches inside the mouth, along with soreness or a burning feeling, it could be oral thrush. This is a fairly common fungal infection that affects people of all ages, from newborns to older adults. It usually looks worse than it is and responds well to the right treatment, but it should not be ignored.
What Is Oral Thrush?
Oral thrush, also called oral candidiasis, is an infection caused by an overgrowth of a yeast called Candida albicans. This yeast lives naturally in small amounts in most people's mouths, digestive tracts, and skin without causing any problems. Thrush develops when something disturbs the natural balance in the mouth, allowing the yeast to multiply and form visible patches on the tongue, inner cheeks, gums, or roof of the mouth.
Common Causes of Oral Thrush
Several factors can allow candida to grow out of control:
- Weakened immunity: Conditions like diabetes, HIV, or cancer treatment can lower the body's ability to keep yeast in check.
- Antibiotic use: Antibiotics can kill helpful bacteria that normally keep candida under control.
- Inhaled steroids: People using steroid inhalers for asthma without rinsing their mouth afterward are more prone to thrush.
- Dry mouth: Reduced saliva flow, from medications or certain health conditions, creates an environment where yeast thrives.
- Ill-fitting dentures: Dentures that trap moisture and are not cleaned regularly can harbour yeast.
- Infancy: Babies can develop thrush due to an immature immune system or exposure during breastfeeding or bottle feeding.
- Uncontrolled blood sugar: High sugar levels in saliva can encourage yeast growth in people with diabetes.
Signs and Symptoms to Watch For
Oral thrush has some fairly distinctive signs, though severity can vary from mild to more noticeable discomfort.
In Adults
- Creamy white or slightly yellow patches on the tongue, inner cheeks, or roof of the mouth
- Patches that may bleed slightly or reveal red, raw tissue when wiped or scraped
- A cottony feeling in the mouth
- Soreness or burning, sometimes affecting taste
- Redness and cracking at the corners of the mouth
- Difficulty swallowing in more advanced cases
In Infants
- White patches on the tongue or inside the cheeks that look like curdled milk but do not wipe away easily
- Fussiness during feeding, as the mouth may feel sore
- In some cases, a diaper rash caused by the same yeast passing through the digestive system
How Oral Thrush Is Diagnosed
A dentist can usually identify oral thrush through a visual examination. The characteristic appearance of the patches, along with a review of your medical history and any recent medications, is often enough for a diagnosis. Occasionally, a small sample may be taken to confirm the yeast under a microscope, especially if the infection keeps returning or does not respond to initial treatment.
Treatment Options for Oral Thrush
Treatment focuses on reducing the yeast overgrowth and addressing any underlying cause.
For Infants
Doctors typically prescribe a mild antifungal gel or liquid applied directly to the mouth for a set number of days. Sterilising feeding bottles, pacifiers, and toys helps prevent reinfection. If breastfeeding, both mother and baby may need treatment to fully clear the infection.
For Adults
Treatment may include antifungal lozenges, gels, or mouth rinses used over one to two weeks. In more persistent or widespread cases, oral antifungal tablets may be recommended. Alongside medication, it helps to:
- Maintain good oral hygiene, including gentle tongue cleaning
- Rinse the mouth after using steroid inhalers
- Clean and soak dentures properly each night
- Manage blood sugar levels if diabetic
- Stay hydrated to support saliva flow
When to See a Dentist in Gurugram
While mild thrush can sometimes be managed with home care, it is best to have any persistent white patches checked, especially if soreness, feeding difficulty, or spreading occurs. Patients across Gurugram visit Dr. Shrey Suri's clinic for an accurate diagnosis, since some other mouth conditions can mimic thrush symptoms. Getting it examined early helps rule out anything more serious and ensures the right antifungal treatment is started quickly.
| Age Group | Typical Treatment Duration |
|---|---|
| Infants | 7 to 10 days with antifungal drops or gel |
| Adults (mild cases) | 7 to 14 days with lozenges or rinses |
| Adults (recurrent or severe) | 2 to 4 weeks, sometimes with oral tablets |
Recovery time can vary depending on overall health, so following the full course of treatment as advised is important even if symptoms improve early.
Frequently asked questions
Is oral thrush contagious?
Oral thrush itself is caused by an overgrowth of yeast that normally lives in the mouth, so it is not typically considered contagious in the way a cold is. However, it can sometimes pass between a breastfeeding mother and baby if one has an active infection.
Can oral thrush go away on its own?
Mild cases in healthy adults sometimes clear up when the underlying cause, such as antibiotic use, is addressed. However, most cases need antifungal treatment to fully resolve and to prevent spreading, so it is best to get it checked.
Is oral thrush the same as leukoplakia or oral cancer?
No, but the white patches can look similar. Thrush patches usually wipe away partially to reveal red or raw tissue underneath, while leukoplakia patches do not. If patches persist despite treatment, a dental check-up is important to rule out other causes.
Why do babies get oral thrush so often?
Infants have developing immune systems and their mouths can pick up candida yeast during birth, from bottle nipples, pacifiers, or breastfeeding. It is common and usually not a sign of anything serious, but it should still be treated.
