Do you ever wonder why there are things in your body that come out late? Do you think that some parts of your body are not needed anymore in today’s environment?
Scientists today are arguing whether wisdom tooth is still relevant. Wisdom tooth is the third molar that many dentists recommend to be pulled out from their patients. If this is the case, does this mean that wisdom teeth don’t have a role anymore?
Many years ago, our ancestors survived by eating raw foods such as meat, nuts, berries, and leaves. Early man didn’t have the tools like knife and fire to cut their food and make it softer to chew. Chewing was tough hence they also needed a broader jaw and stronger sets of teeth- including wisdom tooth.
Having three molars is important to help our ancestors eat the foods to survive. There larger jaw made it easier for them to grow the third molar normally. When the wisdom tooth erupts, it has space where it can grow without disturbing the teeth near it.
Wisdom tooth typically erupts between ages 17-21 years old, the time when most people already developed critical thinking- hence the term “wisdom”. It doesn’t normally come out with the rest of the teeth during the early days of child development. This fact helps the anthropologists determine the age of the bones they unearthed. For example, the “Turkana Boy” which is now on display at the Smithsonian National Museum of Natural History is believed to be eight to nine years old, as he doesn’t have his third molar yet when he died.
Today, we really don’t need a third molar. Look at the foods we eat- most of them are cooked and tender. We have tools in our kitchen to turn them into bite-size or even smaller pieces. Almost everything we serve doesn’t require too much effort to chew. In fact, we disregard meals that are hard to chew and we complain to the restaurant manager if our meals are not tender.
Because chewing food today has become an easy feat to accomplish, our jawline has evolved over millions of years. If you will compare a picture of a modern man versus its ancestors, you will see the difference in the jawline. Man today has a smaller jawline. This means that there is less space to accommodate the third collar. This is the reason Ontario dentists suggest that wisdom tooth must be extracted.Read More
