Radiating pain can be there because of gum infection or can occur because of impacted wisdom tooth present. In case of severe gum infection, periodontitis, pain is usually localized but can radiate deep into the jaw. If wisdom tooth is impacted that is there is not enough space for wisdom tooth to erupt, then severe pain occurs which may also be radiating to head and neck. TMJ pain, infected tooth and systemic problems like heart disorders can also lead to radiating pain in teeth. Without clinical examination, it is difficult to give definite diagnosis. You can visit your dentist for definite diagnosis and treatment. If there is gum infection present, then dental cleaning, root planning and periodontal surgery can be done for the tooth. If impacted wisdom tooth is reason of radiating pain, then surgical extraction of wisdom tooth can be done. If tooth is infected, then treatment is done for infected tooth. If there is TMJ dysfunction present, then physical therapy, muscle relaxants and splints can be given.
