A dental infection, or abscessed tooth, causes an ongoing toothache, swollen neck glands, fever, tooth sensitivity or foul-smelling breath, explains WebMD. Other symptoms include swelling gums or jaw, painful chewing, general discomfort, a bitter taste in the mouth, and an open, draining sore in the gums.
A dentist determines if an abscessed tooth is causing the symptoms, as well as the best route for treatment, according to WebMD. Treatment focuses on getting rid of the infection, protecting the affected tooth and preventing further complications. The toothache caused by the infection may subside if the tooth’s pulp dies, yet the infection continues to spread. Consult a dentist if any symptoms are experienced, regardless of existing tooth pain.
Abscessed teeth are usually caused by severe tooth decay, explains WebMD. Other possible causes include gingivitis, gum disease and trauma to the tooth.
