Wisdom tooth
Wisdom tooth was used by ancient humans to chew plants to have complete nutrition when there was no concept of cooking. Such big teeth were used to cut through and chew big pieces of food but today we have evolved because our way of living has changed, we use fork and knives to cut our food instead of directly chewing it with teeth. Only a few percent of the population bears the pain of the extraction of wisdom tooth and many don’t even extract this tooth. Many go through this painful process because we as humans don’t have enough space in our jaw to make free space inside our mouth.
