Full Answer

Oral thrush is a condition that produces white patches throughout the mouth, including the tongue. It is common in infants, people who wear dentures and those who have a weakened immune system because of conditions like HIV/AIDS, chemotherapy or diabetes.

Leukoplakia arises when the cells on the tongue grow too fast. Although it is not a dangerous condition on its own, it can act as a precursor to oral cancer. Therefore, those who experience it should look out for other signs and discuss the matter with their dentist.
