Final answer:
An adult's permanent dentition consists of 32 teeth, including incisors, canines, premolars, and molars, used for specialized functions in mastication. the correct option is 32.
Step-by-step explanation:
Adult human normal dentition includes 32 permanent teeth. The permanent teeth replace deciduous (baby) teeth after they are lost and consist of 8 incisors, 4 canines, 8 premolars, and 12 molars.
An adult's mouths will typically feature 16 permanent teeth in each jaw, with identical numbers and types of teeth on both the right and left sides. These teeth have specialised shapes to perform various functions in the mastication process.
For example, incisors are used for biting, while canines are employed to tear food. The permanent teeth generally emerge after the deciduous teeth, with the last to appear being the wisdom teeth during late adolescence or early adulthood.
