The whitish coating that can be seen on the top of the tongue will vary from person to person and in different times of the day and can be caused by small particles of food that is trapped within the protrusions on the tongue which is called the papillae which provides the tongue a rough surface. The tongue is composed of three parts, namely the apex which is found at the tip of the tongue, the body which is the visible part of the tongue that extends until the back of the throat and the root which connects the tongue to the base of the mouth.

The blackish discoloration is usually permanent and cannot be removed.
