PARAGRAPH 1: TYPES OF HUMAN TEETH
Adult humans typically have 32 teeth—16 in the upper jaw and 16 in the lower jaw—that fit together and workin concert to chew food. Teeth on the right side of each jaw are usually identical to the teeth on the left side and matching teeth on opposite sides are referred toas sets, or pairs. Humans are heterodonts—that is, they have teeth of different sizes and shapes that serve different functions, such as tearing and grinding. Incontrast, the homodont teeth found in many animals are all the same size and shape, and perform the same function.

PARAGRAPH 2: EXAMINATION FORORAL CANCER
A major reason why oral cancer has such a high mortality rate is that the disease is often detected in its later stages. Early detection greatly improvesthe prognosis. It is essential that patients be examined for oral cancer as a part of their routine visit to their health care professionals, for example dentalvisits. There is no substitute for a thorough, professional examination but self-examination at home on a regular basis may help detect certain oral cancer lesions in theirearlier stages.
