What causes tooth pain in both upper and lower teeth?

Clenching?: Teeth work as a team. If you have pain on both top and bottom, you likely bit down too hard, too long, or both. This can happen with food, and it happens even more often due to clenching & grinding teeth; most of us do it, if you're unaware, it's probably while you sleep. See your dentist to discuss the best solution ;).

Toothpain: There can be pain in the opposite jaw- like a bad tooth in the upper and it feels like both upper and lower teeth hurt- it is called referred pain and most dentist's see it occasionally. Bruxism or clenching can cause it also and many infections either a gum infection or tooth centered infection.

Grinding: Usually stressed patient that grind teeth have those symptoms. It can be muscular/articular.

Disease: Some form of dental disease. Could be caries, periodontal disease, trauma, thermal pain, bruxism. See dentist for assessment.

See DDS: Need to see a radiograph to determine. The pain can be referred or there may be two separate issues. Contact your dentist to take x-rays of the area in question and treat.

Examination: Require complete clinical and radiographic imaging examination to accurately diagnose the problem. However in the absence of obvious decay or abscess or periodontal (gum) disease, the most likely cause is clenching / grinding. Typically this is caused by stress and is termed a parafunctional habit. Important to see your Dentist for evaluation , diagnosis and appropriate treatment. Good Luck.

Many possibilities: As explained here it could be related to your occlusion (bite) that might actually cause pain in both locations or it could be referred pain, with an actual cause in one location and the other pain a ghost that will disappear once the root cause is identified and fixed. It could even be of non-dental origin. You will need an exam and diagnosis to get to the bottom of this..

Night Bruxism: also called night time clenching, may cause pain in the both upper and lower teeth, tooth wear, teeth movement and even damage or break teeth. Currently, no therapy has been proven effective in treating sleep bruxism. See your dentist for night guard fabrication for teeth protection. Good luck.

Broad Question: Many possibilities. Best bet is to be examined by a local dentist. Call for an appointment.
