Wisdom teeth are one of the most consistently problematic parts of your mouth, which is why wisdom tooth extraction is so common.
As the teeth begin to push through the gums, an infection can start around the opening causing pain, swollen gums and jaw stiffness.
There are sacks of fluid called cysts that can form around the tooth before it has erupted and can destroy bone, damage other teeth or cause displacement.
When a wisdom tooth does not grow straight, it can push against neighbouring teeth, causing them to move out of position and the front teeth to crowd, or even cause major damage to the other teeth.
