One less common, but significant cause of tooth pain is a sinus infection. If only your upper teeth on both sides of your face are in pain, sinusitis could be the culprit. This sort of toothache is usually accompanied or preceded by nasal congestion and tenderness around your sinuses.
Toothache occurs from inflammation of the central portion of the tooth called pulp. The pulp contains nerve endings that are very sensitive to pain. Inflammation to the pulp or pulpitis may be caused by dental cavities, trauma, and infection. Referred pain from the jaw may cause you to have symptoms of a toothache.
