Bacteria, viruses and fungi occur naturally in the mouth. The body’s natural defenses and regular oral hygiene generally keep them in check. However, under some situations, they may proliferate and impede or defeat the body’s defenses.
Oral candidiasis, a fungal infection in the mouth, appears to occur more frequently among people with diabetes, including those who wear dentures. If you smoke, have high blood glucose levels or often are required to take antibiotics, you are more likely to have a problem with fungal infections in your mouth.
Diminished salivary flow and an increase in salivary glucose levels create an attractive environment for fungal infections such as thrush. Thrush produces white (or sometimes red) patches in the mouth that may be sore or may become ulcers. It may attack the tongue, causing a painful, burning sensation. It also can cause difficulty in swallowing and compromise your ability to taste.
Your dentist may prescribe antifungal medications to treat this condition. Good oral hygiene is critical.
