If wisdom teeth are causing pain or cannot fully erupt, they are removed. However, many people have their wisdom teeth removed even when not experiencing symptoms. Dentists often suggest removing them to avoid potential problems in the future.
Complications such as impaction, infection, and crooked teeth are common because the human jawbone no longer has the room to accommodate the wisdom teeth. Having the wisdom teeth extracted when you are a teen or in your twenties is easier because the roots of the teeth have not fully developed.
