Most of our mouths do not have room for all our teeth, which can lead to overcrowding and bad teeth. Just 200-300 years ago, our ancestors had sharper teeth and larger jaws than we do. They need large, strong jaws to chew the raw vegetables, meat, and hard foods that often make up their diet.
After the Industrial Revolution there was a huge change in food as we moved from farms to cities and started eating softer foods and cooked foods such as legumes and grains that needed to be digested and less consumed. You do not need to use energy and mouth pressure. Over time, as these changes in nutrition occur, the jaw will become smaller, but the teeth will not replace each other and will remain the same. This situation can lead to lower jaw problems that are common today.
Today, more than 80% of people have impacted wisdom teeth, but wisdom teeth no longer produce teeth. Today, our food has become softer and easier to digest, our jaws and teeth have become shorter, leaving no room for teeth to grow. This is why the jaw is often affected or not well when teeth break in the mouth. This impact on wisdom teeth often leads to infection, pain, and other dental problems. Wisdom teeth have become a degenerated body like an appendix.
