If you think about it, human teeth are an anomaly, especially when you compare our teeth to those of other omnivore mammals. For example, what other species deal with impacted wisdom teeth? Why do other animals have perfectly aligned teeth, yet many humans do not? Why are human teeth so messed up? Interestingly enough, messed up teeth are primarily caused by evolutionary development.
Small Human Jaw
Evidence tells us that our distant hominid ancestors had a much larger jaw than modern-day humans. They also had approximately the same number of teeth, meaning that our modern human jaws are simply too small to contain all dentition. The biggest reason for impacted wisdom teeth is that there is just nowhere for them to grow. Additionally, human teeth typically take up the whole jaw space, unlike other animals. As a result, there is no room for new teeth, such as wisdom teeth, to grow.
Humans Do Not Rely on Perfect Teeth for Survival
Over time, humans have developed the ability to use our hands and to craft tools to deal with food we cannot tear apart with our teeth. As a result, we no longer rely on them for survival as much as other animals. Consequently, further evolutionary development was not needed. As the shape of our faces and jaws changed, our teeth remained the same.
Age is Against Us
Nature only requires human teeth to last about 30 years, giving people enough time to reproduce and to raise children from a biological standpoint. As a result, most people notice that their oral health significantly declines after 30. Even if you managed to escape the need for orthodontics as a teen, you might find that you suddenly have an increase in cavities, chipped teeth, and jaw pain. Additionally, since good teeth are no longer a crucial evolutionary feature, genetic errors, like having crooked teeth, are not selected against.
