Wisdom Teeth Removal: When and Why It’s Necessary Wisdom teeth tend to cause more trouble than they're worth. While some people have no issues, others deal with pain, swelling, and even infections. If your wisdom teeth are making their presence known in all the wrong ways, removal might be the best option. But you might be wondering is extraction necessary. Well, not in all cases. That said, most dental professionals prefer removing them to save the healthy teeth. Keep reading to find out why and when it's necessary. Do Wisdom Teeth Always Need to Be Removed? Not necessarily. If they come through properly aligned and don't cause discomfort, they can stay. But for many Australians, wisdom teeth are a source of ongoing dental problems. Impacted teeth—those that don't have enough space to grow—are common. They can press against neighbouring teeth, cause pain, and increase the risk of infections or cysts. Dentists often recommend removing wisdom teeth before they start causing trouble.
