What is oral candidiasis?
Oral candidiasis, or thrush, is a fungal infection that affects the inside of your mouth.
What causes oral candidiasis?
Oral candidiasis is caused by a type of fungus called Candida. Fungi are normally found in your mouth. When there are too many fungi, it can cause an infection. Babies and the elderly are at higher risk because their immune systems are not as strong. Newborn babies may get thrush if the mother had vaginal candidiasis during delivery. The following may increase your risk of oral candidiasis:
- Medical conditions that suppress your immune system, such as diabetes, cancer, or HIV and AIDS
- Medicines, such as antibiotics, steroids, or chemotherapy
- Radiation therapy to the head and neck
- Dry mouth
What are the signs and symptoms of oral candidiasis?
- White or whitish-yellow patches in the mouth that look like milk curds
- Redness or bleeding under the patches
- Sore and painful mouth, with cracking or tearing on the corners
- Bright red tongue that may feel like it is burning
- Trouble swallowing and tasting
- Swelling under dentures
How is oral candidiasis diagnosed?
Your healthcare provider will ask about your medical history. Tell your provider when your signs and symptoms started. Your provider will examine the inside of your mouth and the area around your mouth. Your provider will also rub a cotton swab on one of the patches and check it under a microscope.
How is oral candidiasis treated?
Antifungal medicine helps kill the fungus that caused your oral candidiasis. This medicine may be a pill or a solution that you gargle. Remove dentures before you gargle.

How can I help to prevent oral candidiasis?
