Wisdom teeth are third molars in the back of the mouth, usually appearing during adolescence or early adulthood. These teeth are required for us to grind mostly solid food.

Every human has four wisdom teeth. In some cases, wisdom teeth are properly aligned and grow functionally, but in many cases, they grow incorrectly, causing problems such as discomfort, pain, infection, etc. If there are more problems, sometimes wisdom teeth need to be removed.
