When disc brakes for high performance cars arrived on the scene we began to hear of warped brake discs on road going cars, with the same analyses and diagnoses. Typically, the discs are resurfaced to cure the problem and, equally typically, after a relatively short time the roughness or vibration comes back.
As a result, the cheek teeth, like the incisors, have evolved to continuously grow throughout life. In other rodents, the diet of tubers, seeds, and grain requires little chewing, resulting in little wear of the cheek teeth.
Wisdom teeth are so called because they are the last teeth to come in, at about the time of young adulthood -- the age when a person gains maturity and thus wisdom. The majority of us have most of our permanent (adult) teeth by age 13, followed by our wisdom teeth (third molars), which usually push their way through the gums or become impacted between ages 17-21.
