A filling is a material that your dentist uses to fill a cavity after he or she removes any tooth decay. To fill a tooth, your dentist will: 1  Numb your teeth, gums, tongue, and surrounding skin. 2  Sometimes use a small sheet of rubber on a metal frame (rubber dam) to target the decayed tooth and to stop liquid and tooth chips from entering your mouth and throat. 3  Drill out all the decay and replace it with a filling.

The unrestricted mode is often called kernel mode, but many other designations exist (master mode, supervisor mode, privileged mode, supervisor state, etc.). Restricted modes are usually referred to as user modes, but are also known by many other names (slave mode, problem state, etc.). In kernel mode, the CPU may perform any operation allowed by its architecture; any instruction may be executed, any I/O operation initiated, any area of memory accessed, and so on. In the other CPU modes, certain restrictions on CPU operations are enforced by the hardware.
