Nature
Leukoplakia on the lip is most often due to solar-induced damage from repeated sun exposure. A bad habit of biting the inside lip could also result in a lesion. Leukoplakia is seen in smokers because of chronic heat irritation from the cigarette filter or pipe. Chewing tobacco or snuff is also a cause of leukoplakia inside the cheek.
