Linea alba buccalis  

Linea alba buccalis is a horizontal white ridge seen on the buccal mucosa at the level of the occlusal plane of the teeth. This is a hyperkeratotic lesion caused by friction from the teeth. This is found in almost every individual at varying degrees and may be mistaken for leukoplakia.
