The most frequent clinical problem we see is pericoronitis, (a localized gum infection). Without enough room for total eruption, the gum tissue around the wisdom tooth can become irritated and infected, resulting in recurrent pain, swelling, and problems with chewing and/or swallowing.
Non-infectious diseases may also arise in association with an impacted wisdom tooth. Cysts are fluid-filled “balloons” inside the jaw bone that develop as a result of impacted teeth and slowly expand destroying adjacent jaw bone and occasionally teeth. They can be very difficult to treat if your wisdom teeth are not removed in your teenage years. Although rare, tumors can be associated with the delayed removal of wisdom teeth.
Impacted wisdom teeth may contribute to the crowding of your teeth. This is most noticeable with the front teeth, primarily the lower front teeth, and is most commonly seen after a patient has had braces. There are a number of factors that cause teeth to crowd after braces or in early adulthood. Retained, impacted wisdom teeth may be a contributing factor. Unless you have an active problem, the reason for removal is primarily to prevent long-term damage to your teeth, gums, and jaw bone.
Damage to Adjacent Teeth
If there is inadequate room to clean around the wisdom tooth, the tooth directly in front, the second molar, can be adversely affected resulting in gum disease, bone loss around the tooth, and/or decay.
