Sinus vs Dental Toothache: How to Tell the Difference

October 17, 2025

Tooth pain can be confusing because it might come from dental problems or sinus issues. How to know if your toothache is sinus-related or dental-related? Understanding the signs helps you get the right treatment fast.



Signs of Sinus-Related Toothache

Sinus infections can cause pressure and pain in upper teeth, especially the back molars. This pain often feels like a dull, aching pressure and may affect several teeth at once. You might also notice nasal congestion, facial pressure around your cheeks or forehead, runny nose, or headaches. Sinus pain often worsens when bending over or changing position.


Signs of Dental-Related Toothache

A dental toothache usually comes from a specific tooth affected by cavities, infection, cracks, or gum disease. The pain is often sharp, throbbing, or localized to one area. You may experience sensitivity when biting, chewing, or with hot and cold food. Dental pain lasts longer and is not typically linked to nasal symptoms.

How to Check

Try pressing gently on the affected tooth or gums. Increased pain suggests a dental cause. Sinus pain tends to be deeper and more spread out. If nasal symptoms coexist with upper tooth pain, sinusitis is likely involved.
