Wisdom teeth often cause pain, crowding, and infection, but why do they need to be removed? Kevin Molldrem DDS breaks down the reasons behind wisdom tooth extractions. Many people's jaws don’t have enough space for these extra molars, leading to impaction or misalignment. If left untreated, impacted wisdom teeth can damage neighboring teeth, cause cysts, or increase the risk of gum disease. While not everyone needs removal, early evaluation helps determine the best course of action. If you experience discomfort or swelling, consulting a dentist can prevent future complications.
