Final answer:
Third molars emerge between late adolescence and early adulthood, around 17 to 25 years of age, or they may not emerge at all.
Step-by-step explanation:
The third molars, commonly known as wisdom teeth, generally emerge between the ages of late adolescence and early adulthood, which can typically be somewhere around 17 to 25 years of age or, in some cases, they may not emerge at all. During middle childhood, most of the permanent teeth replace the deciduous teeth. Incisors and premolars are typically lost and replaced earliest, followed by canines and then second molars. It is after these stages that third molars will emerge if they are going to. There is a chance that third molars will remain impacted within the jaw and require orthodontic surgery to remove them if they pose any problems.
