All of my teeth hurt.  I have trigeminal neuralgia on one side but it has been under control with medication.  This pain is different from that pain and now includes the upper and lower teeth on both sides.   I have been to the dentist and an endodontis and had xrays and nothing is wrong with my teeth.
Hi. Thanks for the query. The symptoms of pain in upper and lower teeth with no signs of any tooth decay can be probably due to Identical hypersensitivity that is due to opening of the terminal nerve endings on teeth. So my advice is to start using anti sensitivity toothpaste for at least 15 days and see if the symptoms improve. Also avoid taking very hot and cold foods, take your food only after cooling it to room temperature. If the pain is annoying you can take anti-inflammatory painkillers like Ibuprofen but only if needed. Hope this helps. Regards.
