Oral Thrush (Candidiasis): Causes, Symptoms and Treatment
If you have noticed creamy white patches on your tongue or inner cheeks, or a burning soreness that will not go away, you may be dealing with oral thrush. This is a common fungal infection that many patients in Indirapuram, Ghaziabad come to us about, often feeling worried or embarrassed. The good news is that oral thrush is usually easy to diagnose and treat once the cause is identified.
What Does Oral Thrush Look Like?
Oral thrush, medically known as oral candidiasis, is caused by an overgrowth of a yeast called Candida that naturally lives in small amounts in everyone's mouth. When conditions allow it to multiply, symptoms can appear suddenly.
- Raised, creamy white or yellowish patches on the tongue, inner cheeks, gums, tonsils, or roof of the mouth
- Patches that look a bit like cottage cheese and may bleed slightly if scraped
- Redness, soreness, or a burning sensation underneath or around the patches
- A cottony feeling in the mouth
- Loss of taste or an unpleasant, slightly metallic taste
- Cracking and redness at the corners of the mouth (angular cheilitis)
- Pain while swallowing in more severe cases
In some people, especially denture wearers, thrush can also appear as persistent redness under the denture rather than obvious white patches.
Why Does Oral Thrush Happen?
Candida overgrowth usually has a trigger. Understanding the cause helps prevent it from coming back.
Antibiotics
Antibiotics kill harmful bacteria, but they can also wipe out the good bacteria that normally keep Candida in check. This is one of the most common reasons people develop thrush shortly after finishing a course of antibiotics.
Dentures
Ill-fitting dentures, or dentures that are not cleaned and removed at night, create a warm, moist environment where yeast thrives. This is a frequent cause of thrush in older adults, and we see it often in our Indirapuram patients who wear full or partial dentures.
Diabetes
Higher sugar levels in saliva, common in uncontrolled or undiagnosed diabetes, feed yeast growth. Recurring thrush can sometimes be an early sign that blood sugar levels need checking.
Weakened Immunity
Conditions or treatments that lower immune defences, such as chemotherapy, steroid inhalers, HIV, or chronic illness, make it easier for Candida to overgrow. Steroid inhalers used for asthma are a particularly common, often overlooked, cause.
Other Contributing Factors
- Dry mouth from medication or dehydration
- Smoking
- A diet high in sugar
- Pregnancy, due to hormonal changes
- Infancy, since babies have developing immune systems
How Is Oral Thrush Diagnosed?
In most cases, a dentist or doctor can diagnose oral thrush simply by examining your mouth and asking about your medical history, recent medications, and denture use. If the diagnosis is not clear, or the infection keeps returning, further checks may be suggested.
- A gentle scraping of the white patch examined under a microscope
- A swab sent for lab culture to confirm the type of yeast
- Blood tests to check for diabetes or other underlying conditions if thrush is recurrent
How Is Oral Thrush Treated?
Treatment depends on how mild or severe the infection is and what is causing it.
- Antifungal medication: Prescription antifungal gels, lozenges, or rinses are the standard treatment and usually clear mild to moderate cases within one to two weeks.
- Oral antifungal tablets: For more widespread or stubborn infections, tablets may be prescribed for a short course.
- Denture care: Cleaning dentures daily, removing them at night, and getting an ill-fitting denture adjusted can resolve denture-related thrush.
- Managing underlying conditions: Getting blood sugar under control, switching inhaler technique, or rinsing the mouth after steroid inhaler use can prevent recurrence.
- Good oral hygiene: Brushing twice daily, cleaning the tongue gently, and staying hydrated support recovery and lower the chance of it returning.
When to See a Dentist
You should get your mouth examined if white patches do not go away within a week or two, if soreness is affecting your eating or speaking, or if thrush keeps coming back despite treatment. At Dr Urvashi Verma's Dental Clinic in Indirapuram, we examine the mouth carefully, identify likely causes, and guide you on the right antifungal treatment along with any lifestyle or denture adjustments needed.

Frequently asked questions
Is oral thrush contagious?
Oral thrush itself is generally not easily passed between adults through casual contact, but the fungus can spread from mother to baby during breastfeeding or to a partner in rare cases. People with weak immunity should be more cautious around active infections.
Can I treat oral thrush at home?
Mild cases sometimes improve with better oral hygiene, cleaning dentures properly, and rinsing with warm salt water. However, persistent or painful patches need antifungal medicine prescribed by a dentist or doctor, so it is best to get it checked rather than wait it out.
Why do I keep getting thrush even after treatment?
Recurring thrush often points to an underlying cause that has not been addressed, such as uncontrolled diabetes, ill-fitting dentures, dry mouth, or repeated antibiotic use. Treating the root cause along with the infection helps prevent it from coming back.
Does oral thrush mean I have a serious health problem?
Not necessarily. Many cases happen after a course of antibiotics or with denture use and clear up with simple treatment. But since thrush can sometimes signal diabetes or a weakened immune system, it is worth getting checked, especially if it keeps returning.
