Leukoplakia causes thick, white patches inside the mouth. They may cause pain and make it hard to eat some foods. Over time, some of the patches may turn into cancer.

It is treated with changes to lifestyle habits, such as stopping smoking and dental care. Some people may need surgery to remove patches that do not go away or show signs of cancer. Sometimes, people turn to natural therapies to help control the patches.
