24 male....enlarged submental and submandibular node on both side....molar tooth on both side hurts and infected reason?

Infection: Infections of teeth can be due to endodontic or periodontal causes. Infections can cause the swelling. They need to be treated by a dentist, so the sooner you are seen the better you will feel. Submandibular swellings can rapidly expand, closing off your airway and causing a life threatening situation. Could be your wisdom teeth.

See a dentist ASAP: A tooth infection won't go away without treatment and the infection may spread to your jaw, cheeks, sinus and to other areas of your body. Dentist will treat a tooth abscess by treating the cause and getting rid of the infection. See your dentist ASAP for tooth infection treatment.

Enlarged nodes: Infections spread to other parts of the body and can lead to serious complications including death. An infected tooth can spread infection to adjacent lymph nodes which are the body's attempt to try to contain the infection. Get a dental evaluation and treatment asap. This will not go away; it will only get worse. Even in the absence of pain, there is hidden danger.
