Wisdom teeth, or third molars, are typically the last adult teeth to emerge, usually between the ages of 17 and 25. Because they come in after the rest of your teeth have developed, there is often not enough room at the back of the mouth to accommodate them. As a result, they may grow at an angle, push against neighbouring teeth, or remain trapped beneath the gums or jawbone. This condition is known as impaction.
Impacted or partially erupted wisdom teeth can lead to a range of problems. These may include pain, swelling, difficulty cleaning the area, and increased risk of decay or gum disease. In some cases, cysts can form, or the surrounding bone and nerves may be affected. Even if you are not experiencing any discomfort now, wisdom teeth can still cause complications in the future.
