Oral Thrush (Candidiasis): Causes, Symptoms and Treatment
If you have spotted white patches on your tongue, cheeks, or the roof of your mouth, or noticed your tongue looks unusually coated, you may be dealing with oral thrush. This is a common and treatable fungal infection. Here is what causes it, how to recognise it, and what treatment usually involves.
What Is Oral Thrush?
Oral thrush, also called oral candidiasis, is an infection caused by an overgrowth of a yeast called Candida. Small amounts of this yeast live naturally in most people's mouths without causing any problems. Thrush develops when something disrupts the normal balance, allowing the yeast to multiply and cause visible symptoms.
Common Causes
Several factors can make the mouth more welcoming to yeast overgrowth. These include:
- Weakened immunity, from illness, certain medications, or conditions like uncontrolled diabetes
- Recent antibiotic use, which can reduce the good bacteria that normally keep yeast in check
- Ill-fitting dentures or poor denture hygiene
- Dry mouth, whether from medication side effects, dehydration, or certain health conditions
- Inhaled steroid use for asthma or COPD without rinsing the mouth afterwards
- Smoking
- Poor oral hygiene in general
Infants and older adults tend to be more prone to thrush, as are people undergoing chemotherapy or those with weakened immune systems.
Symptoms to Watch For
Oral thrush has some fairly recognisable signs, though they can vary in severity:
- Creamy white or slightly yellow patches on the tongue, inner cheeks, gums, tonsils, or roof of the mouth
- Patches that may look like cottage cheese and can sometimes be gently wiped away, revealing a red or raw area underneath
- A cottony feeling in the mouth
- Loss of taste or an unpleasant taste
- Redness or soreness that can make eating or swallowing uncomfortable
- Cracking and redness at the corners of the mouth
- In more severe cases, mild bleeding if the patches are disturbed
When a Coated Tongue Is Not Thrush
Not every coated or white tongue is thrush. A simple whitish coating that comes from food debris, dehydration, or reduced tongue cleaning often looks patchy but uniform, and it usually improves with better brushing and tongue cleaning. Thrush tends to appear in raised, distinct patches and does not resolve with hygiene alone. If you are unsure, a dental check is the simplest way to tell the difference.
Is It Serious?
In most healthy adults, oral thrush is uncomfortable but not dangerous, and it responds well to treatment. That said, it should not be ignored, particularly if it keeps coming back, spreads to the throat, or occurs alongside other symptoms like unexplained weight loss or persistent fatigue. These can sometimes point to an underlying condition that needs attention, such as poorly controlled diabetes or an immune-related issue.
Treatment Options
Treatment depends on how mild or extensive the infection is, but generally includes:
- Antifungal medication, such as an oral gel, lozenge, or liquid rinse prescribed for a set number of days
- For more widespread or persistent cases, an antifungal tablet may be recommended
- Addressing the underlying cause, such as adjusting denture fit, improving denture cleaning routines, or rinsing the mouth after using an inhaler
- Improving daily oral hygiene, including gentle tongue cleaning
- Managing dry mouth with adequate hydration or products recommended by your dentist
Most cases improve within one to two weeks of appropriate treatment. If thrush keeps returning, further evaluation may be needed to understand why.
| Situation | What Usually Helps |
|---|---|
| Denture-related thrush | Denture cleaning routine, refitting if loose, antifungal gel |
| Post-antibiotic thrush | Short course of antifungal treatment |
| Dry mouth related thrush | Hydration, saliva support, antifungal treatment |
| Recurrent thrush | Antifungal treatment plus checking for underlying health causes |
Cost of Treatment
Treatment cost depends on the medication prescribed and whether any dental adjustments, such as denture refitting, are needed. As a general guide for patients in Sector 39, Gurugram, a typical range for a dental consultation and basic antifungal treatment plan is modest, while additional procedures like denture adjustments would add to this. Your dentist can give you a clearer estimate after an examination.
When to See a Dentist
If you notice white patches that do not go away within a few days, spreading soreness, or discomfort while eating and swallowing, it is a good idea to get it checked rather than wait it out. Early treatment tends to clear thrush faster and more comfortably.

Frequently asked questions
Is oral thrush contagious?
Oral thrush itself is generally not easily passed between adults through casual contact, but it can spread from a mother to a baby during breastfeeding, or between partners in some cases. Good hygiene reduces this risk.
Can I just wipe off the white patches myself?
You can gently check by wiping with a clean, damp gauze. If the patch comes off leaving a red or slightly bleeding area underneath, this is typical of thrush. Avoid repeatedly scraping at home, as it can irritate the tissue.
Will oral thrush go away on its own?
Mild cases in otherwise healthy people sometimes clear up once the underlying trigger is removed, such as stopping an inhaler rinse habit or improving denture hygiene. However, most cases need antifungal treatment to resolve fully and to prevent recurrence.
Does oral thrush mean I have a serious health problem?
Not necessarily. Many cases are linked to simple causes like antibiotic use, dentures, or dry mouth. However, recurring or severe thrush can sometimes point to an underlying condition like diabetes, so it is worth getting checked.
