Leukoplakia is a condition in which thickened, white patches are formed on gums, inner portion of the cheeks, bottom of the mouth and sometimes on the tongue. These patches cannot be easily scraped off. Sometimes this disease is precancerous.

Leukoplakia is primarily caused by the use of tobacco. Other agents that causes leukoplakia are Candida albicans (a form of yeast which causes oral and genital infections in humans), long term use of alcohol and other chronic irritants ”smokeless tobacco” products. Smoking is also responsible for most cases of leukoplakia.  

Leukoplakia can be prevented by avoiding all tobacco products and is one of the best steps for prevention. Avoiding or limiting alcohol consumption prevents this disease. Eating plenty of fresh fruits and vegetables which are rich in antioxidants such as beta carotene, reduces the risk of leukoplakia by deactivating harmful oxygen molecules before they can damage tissues.
