Occlusal surfaces of the right and left cheek teeth arcades

The occlusal surfaces of the cheek teeth show the enamel ridges forming blade like structures across the occlusal surfaces of the teeth. The indentation between each enamel ridge corresponds to the shape of the occlusal surface of the opposing tooth. Each enamel ridge occludes with the enamel edges of the opposing teeth, which makes the cheek effective in shearing through vegetation.
