The third set of molars near the back of your mouth, wisdom teeth are among the last teeth to develop; they typically appear when you are in your late teens or early twenties. If there’s not enough space for these extra teeth on your jaw, they may come in at an awkward angle or remain stuck between your jawbone and gum tissue, becoming impacted.
Impacted wisdom teeth can lead to a host of problems, including swollen gums, displacement of nearby teeth and infections caused by bits of food lodged in the jaw area behind the tooth. In severe cases, it can even cause cysts or tumors to form in or around your jaw. Experts recommend removing impacted wisdom teeth before you turn 30; your jawbone will still be flexible enough to make extraction easier and the healing process quicker.
