Poorly positioned impacted teeth can cause many problems. Partially erupted through the gums it is difficult to keep the area clean. This results in food getting stuck, and plaque and tartar begin to build up. Discomfort my progress to pain, swelling and jaw stiffness as gum infection develops. Cavities may also form on either wisdom tooth or the second molar in front. People who have wisdom teeth removed when they are younger tend to have a quicker recovery (less pain and swelling) and fewer complications.
More serious problems are rare but can occur when tumours or cysts form around impacted wisdom teeth resulting in the destruction of the jaw bone and healthy teeth.
