The story behind wisdom tooth

The wisdom tooth was more helpful to our early ancestors who ate roots and food which was not soft. So, they needed an extra chewing tooth. Human jaw used to be larger, so these third molars were used for tearing food. Over time jawbone started getting smaller and all 32 teeth could not fit properly. And with time our eating habits too changed as man began to cook food and use spoons and knives to cut food. So, the role of wisdom teeth is no longer significant. Due to less space, wisdom teeth can push up against other teeth causing dental concerns. They can grow sideways or never erupt at all, increasing the risk of cavities. Not everyone has these teeth. Most people get it extracted to avoid future dental complications.
