What is the role and purpose of having wisdom teeth?

Wisdom teeth comprise a kind of backup plan, a safety net, a backup system to ensure there will be teeth to use for the duration of the lifetime. It is the molars that are the workhorses of dentition because much of eating is grinding food down into manageable pieces that can be swallowed easily, and will aid digestion, and that is why the wisdom teeth are the back teeth. In earlier eras, the jaw anatomy was more forgiving and there was usually no problem accommodating the wisdom teeth as an extra reinforcement that would be beneficial and help to compensate if there were a mishap causing a tooth loss. We have commented previously that humans have been manipulated genetically, and that is the reason why so many these days have problems with their wisdom teeth that lead to removal because there is not room. That imbalance was imposed by the interlopers, not as a specific aim but through their inadvertent tinkering with human genetics, experimenting on you as lab rats to see what will happen. Anything deleterious they would typically retain, if not outright lethal, because they simply do not care if it causes suffering and, in fact, enjoy that when it happens and take pride in their prowess in manipulating things for the worst.
