Symptoms of an impacted wisdom tooth include bad breath, jaw pain, and red, swollen gums, according to Mayo Clinic. Impacted wisdom teeth may also cause swelling around the jaw and an unpleasant taste in the mouth.
An impacted tooth may not cause any symptoms, reports Colgate. Symptoms are often due to swelling or infection of the gum on top of the impacted wisdom tooth. Food and plaque can stick to tissue surrounding impacted tooth, causing swelling of the gums and bad breath, reports MedlinePlus.
Impacted wisdom teeth can also cause gingiva, which is tenderness or pain in the gums, according to MedlinePlus. The jaw may become painful, leading to jaw aches and headaches. An impacted tooth may occasionally cause swelling of lymph nodes in the neck.
An unpleasant taste when eating or biting down on the area is another symptom of an impacted wisdom tooth, reports MedlinePlus. There may be a visible gap where the impacted wisdom tooth did not emerge. The gums around the impacted tooth may show signs of infection, such as drainage and redness. Abscess of the gum area or tooth, malocclusion of teeth and chronic mouth discomfort are symptoms of complications caused by an impacted wisdom tooth.
