Around 35% of people never grow wisdom teeth in their entire lifetimes. Various factors like genetics and race can be responsible. If you do have them, you’re likely to see the third set of molars erupting between the ages of 17 to 25. That’s when the dental arch becomes big enough for the teeth to develop.
Depending on the skeletal structure of your face, you may grow the extra set of molars only in the lower jaw. While 20 baby teeth are present in the gums when you’re born, wisdom teeth develop only in adulthood. Many people choose to go in for the extraction procedure just to avoid any problems in the future.
