For most people wisdom teeth grow on both sides, as they are our normal teeth, professionally known as 3rd molars. It is only because it erupts last, usually after a person is 18 years old, and it erupts after a person’s mind has matured that it is also known as a wisdom tooth. The reason why so many people are now concerned about whether or not their wisdom teeth are erupting is because as humans have evolved, the food we eat has become softer and more refined. Our jaw development is relatively small, and our smaller jaws do not accommodate the eruption of all the teeth in our mouths. This results in the phenomenon of ectopic eruption of wisdom teeth, which is prone to a series of problems such as wisdom tooth pericoronitis, so many modern people wish they did not have wisdom teeth. Of course this situation is now also very common in the clinic. As people continue to evolve, 1 part of the population has developed congenital absence of wisdom teeth. Some may be missing 1, some may be missing 2, 3 or 4. However, for most people, wisdom teeth grow on both sides, and relatively few people are missing all of them or one side of them.
