Why does your sinus hurt weeks after back tooth pulled?

It is unlikely that your sinus would be hurting weeks after having a back tooth pulled. Your sinuses are located near the bridge of your nose and cheeks, while your back teeth are located in the upper or lower jaw. However, here are some possible explanations for pain in the sinus area:

- Referred Pain: sometimes pain in the sinus can be referred pain from the tooth extraction site. When a nerve around the tooth becomes irritated or inflamed during the extraction, it can lead to pain that feels like it's in the sinuses.

- Sinusitis: Sinusitis is inflammation or infection of the sinuses, causing congestion nasal discharge, and pressure in the face and around the eyes. While it is not usually associated with having a tooth pulled, it is possible for the changes in pressure within the sinuses caused by the extraction to trigger or worsen an underlying sinus condition.

- Dental Infection: If the tooth that was extracted was infected, the infection could have spread to the surrounding area, including the sinuses. In this case, you would likely have additional symptoms such as swelling, fever, and difficulty breathing.

- Dry socket: Dry socket is a painful condition that can occur when the blood clot at the extraction site dissolves prematurely, exposing the bone and nerves. This can cause severe pain that may be perceived in the jaw, sinus, or other parts of the face.

If the pain in your sinus persists or becomes worse, it's important to consult with your doctor or a dentist for proper evaluation and treatment.
