You sound like you are describing an organelle.
The special normal or proper activity of an organ or part is called its function.
Dictionary.com defines an "organ" as "a grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf or stamen in plants, that performs a specialized task." American Heritage Dictionary defines "organ" as "a differentiated part of an organism, such as an eye, wing, or leaf, that performs a specific function." It would appear that the tooth does qualify as an organ because it is a grouping of tissues (enamel, cementum, dentin, nerve, blood vessels) in a distinct structure (the hardest part of the body) and in concert with the jaws, it performs a specialized function (cutting, ripping, and grinding of food; the initial phase of digestion.)
Yes, an organ system is a group of organs and tissues that work together to perform specific functions in the body. Each organ within the system has a specialized role that contributes to the overall function of the system. Examples of organ systems include the digestive system and the respiratory system.
when cells become specialized, they take up a particular function in the body, and they adapt their shape and function according to it i.e. a white blood cell is specialized as it is full of enzymes that fight off harmful bacteria. another is a nerve cell, designed for transferring "messages" through the body
An organ is a specialized structure in a multicellular organism that performs a specific function or functions. Organs are made up of different tissues that work together to carry out their job within the body. Some examples of organs include the heart, lungs, and kidneys.

It is hard to state the number of different 'Systems'. Each organ system performs a unique function.
An organ is a cluster of different tissues doing the same function. Wheres a tissue is a collection of many cells doing the same function.
An organ is a structure that has a definite form and performs a definite function or functions within the body.
