There may be no indication that the wisdom teeth need to be removed. It will depend on what the dentist or oral surgeon determines from the x-rays. If there is identifiable misalignment or other issues present, removal will be recommended. The incoming wisdom teeth may cause swelling of the gums before they emerge. When this happens a flap of skin may form around the tooth that allows for food and bacteria to be trapped in. The area can become inflamed. It is possible for this to happen before the teeth emerge, as well. Jaw stiffness or pain can also be a sign of a problem. The teeth can push against the jaw bone or the other teeth causing pain. This will create a feeling of stiffness when you open your mouth. Sinus issues are also a possibility. This happens when the top wisdom teeth put pressure on the sinuses which can cause headaches, congestion, and pain. Bad breath and/or an unpleasant taste in the mouth are also signs the wisdom teeth are starting to emerge.
