What Is Thrush?
Thrush is a common yeast infection of the mouth or throat caused by overgrowth of the fungus Candida albicans. Normally present in small amounts, Candida can multiply rapidly under certain conditions, leading to creamy white patches, redness, and discomfort.
Common Causes and Risk Factors
Antibiotic use - kills healthy bacteria and allows yeast to overgrow
Weakened immune system - HIV, diabetes, cancer treatments, or other immunosuppressive conditions
Inhaled corticosteroids - can leave residue that encourages fungal growth
Poor denture hygiene - ill-fitting or unclean dentures create a breeding ground for yeast
Babies and infants - underdeveloped oral immunity makes them more susceptible
Signs and Symptoms
White or yellowish patches on the tongue, inner cheeks, roof of mouth, or throat
Red, inflamed areas that may bleed if rubbed or scraped
Burning, itching, or “cottony” sensation in the mouth
Difficulty eating, swallowing, or speaking
How Dr. Scott Diagnoses Thrush?
Dr. Scott uses a step-by-step approach:
Medical History and Exam
He reviews your symptoms, recent antibiotic or inhaler use, immune status, and other risk factors before examining your mouth and throat.
Oral Inspection
Using a gentle tongue depressor or scope, Dr. Scott looks for the classic creamy white patches, redness, and soreness that indicate thrush.
Microscopy & Culture
If the diagnosis isn't clear or the infection is severe, he'll swab a small sample of the lesions for microscopic evaluation and Candida culture.
Advanced Evaluation (if needed)
In rare or recurrent cases, additional lab tests or an endoscopic throat exam may be performed to rule out other conditions.

Frequently Asked Questions
How do babies get thrush?
Babies can develop thrush when Candida albicans passes during birth or is transferred from a caregiver's mouth. A warm, moist environment and an immature immune system allow the fungus to overgrow.
What causes thrush in babies?
Thrush in infants is often triggered by underdeveloped oral defenses, antibiotic exposure, or residual milk on the tongue that feeds yeast.
How do I remove thrush from my baby's mouth?
Gently wipe your baby's mouth and tongue with a clean, damp cloth after feedings. Your pediatrician may also prescribe diluted gentian violet or nystatin drops for stubborn cases.
Is gentian violet for thrush safe?
When used sparingly and under medical supervision, gentian violet can be effective against infant thrush. Be aware it may stain surfaces and irritate delicate tissues.
How long does thrush last?
With proper treatment, most thrush infections clear up within 7-14 days. Severe or recurrent cases may take longer and require follow-up care.
Can thrush spread to adults?
Yes. Candida can spread through kissing or sharing utensils. Good oral hygiene and avoiding shared personal items help prevent transmission.
When should I see a specialist?
Schedule an appointment with Dr. Scott if you experience persistent oral pain, difficulty swallowing, or recurring thrush despite home remedies.
