Oral Thrush: Causes, Symptoms and Treatment
Noticing white patches inside your cheeks, on your tongue, or a persistent burning feeling in your mouth can be worrying. One common cause behind these symptoms is oral thrush, a fungal infection that affects both adults and children. It is usually manageable once identified correctly, but understanding what triggers it helps prevent it from coming back.
What Is Oral Thrush?
Oral thrush, also called oral candidiasis, happens when a naturally occurring fungus called Candida albicans grows out of control inside the mouth. Small amounts of this fungus live in most people's mouths without causing any problems. Thrush develops when something disrupts the natural balance of bacteria and fungi, allowing Candida to multiply and form visible patches.
Common Causes in Adults and Children
Several factors can allow Candida to overgrow. Some of the most frequent causes we see at our Chhatarpur Enclave clinic include:
- Weakened immunity: Conditions like diabetes, HIV, or cancer treatment can lower the body's ability to keep fungal growth in check.
- Antibiotic use: Antibiotics can kill helpful bacteria that normally keep Candida under control.
- Inhaled steroids: Asthma inhalers, if the mouth is not rinsed after use, can encourage fungal growth.
- Dry mouth: Reduced saliva flow, from certain medications or medical conditions, removes a natural defence against infection.
- Dentures: Ill-fitting or poorly cleaned dentures create a warm, moist environment where Candida thrives.
- Infancy and old age: Babies and elderly individuals often have less mature or weaker immune responses, making them more susceptible.
- High sugar diet: Sugar feeds Candida, so diets high in refined sugar can contribute to overgrowth.
In babies, oral thrush is fairly common and often linked to an immature immune system or transfer during breastfeeding if the mother has a yeast infection.
Symptoms to Watch For
Oral thrush can look and feel different depending on severity, but typical signs include:
- Creamy white or slightly yellow patches on the tongue, inner cheeks, gums, tonsils, or roof of the mouth
- Patches that may bleed slightly if scraped
- A burning or sore sensation, especially while eating or swallowing
- A cottony feeling in the mouth
- Loss of taste
- Redness or cracking at the corners of the mouth
- In infants, fussiness during feeding and visible white patches on the tongue or cheeks
If patches are wiped away and leave a red, sometimes bleeding surface underneath, this is a fairly classic sign of thrush rather than milk residue or normal coating.
How Oral Thrush Is Diagnosed
A dentist or doctor can usually identify oral thrush by examining the mouth. In some cases, a small scraping of the patch may be examined under a microscope or sent for testing to confirm the diagnosis, especially if the infection is severe, recurrent, or not responding to initial treatment.
Treatment Options
Treatment depends on the person's age, overall health, and how widespread the infection is.
Antifungal Medication
The main treatment is antifungal medicine, available as:
- Oral gels or liquids applied directly to the affected areas
- Lozenges that dissolve slowly in the mouth
- Antifungal tablets for more widespread or persistent infections
Most mild cases clear up within one to two weeks of consistent treatment.
Addressing the Underlying Cause
Since thrush often signals an underlying issue, we also look at contributing factors such as denture hygiene, diabetes control, or inhaler technique. Correcting these reduces the chance of recurrence.
Supportive Care
- Rinsing the mouth with warm salt water
- Maintaining good oral hygiene, including cleaning dentures thoroughly every day
- Reducing sugary foods and drinks
- Staying hydrated to support saliva flow
Typical Cost Range for Treatment
Costs for managing oral thrush in Chhatarpur, New Delhi vary based on the medication prescribed and whether further tests are needed. As a general guide, the typical range for a consultation along with basic antifungal treatment is modest, while additional diagnostic tests or management of an underlying condition may add to the cost. Your dentist can give you a clearer estimate after an examination.
When to See a Dentist
It is worth getting a professional opinion if white patches do not clear within a week, keep coming back, spread, or are accompanied by fever, difficulty swallowing, or significant pain. Early treatment usually resolves thrush quickly and comfortably.

Frequently asked questions
Is oral thrush contagious?
Candida is naturally present in most mouths, so thrush itself is not typically considered contagious in the way a cold is. However, it can pass between a breastfeeding mother and baby if one has an active infection, so both may need treatment together.
Can I treat oral thrush at home?
Mild cases sometimes improve with better oral hygiene, reduced sugar intake, and salt water rinses, but persistent or spreading white patches need antifungal medication from a doctor or dentist. Home care alone rarely clears an established infection.
Why do I keep getting oral thrush repeatedly?
Recurrent thrush often points to an underlying cause such as uncontrolled diabetes, dentures that are not cleaned properly, prolonged inhaler use without rinsing, or a weakened immune system. It is worth getting checked to identify and address the root cause.
Does oral thrush hurt?
It can cause a burning or sore sensation, especially when eating spicy, salty, or acidic foods, and some people notice a cottony feeling or loss of taste. Severity varies from mild irritation to significant discomfort.
