Does tooth ache cause headache?
Patient: For the past few years, I have had a headache in my right side, which only comes when I have a tingling in the same right molar.  I have recently been to the dentist and they told me that I have no cavities or need for a root canal on that tooth.  I am wondering if it could possibly be a really old filling that needs to be replaced, that is possibly triggering a nerve and causing a headache. Doctor: HiWith your query, as you mentioned you already had a filling did your dentist checked for any secondary caries or lesion under the already filled tooth? Moreover you have mentioned you are having headaches from years did you ever consulted your general physician for this problem? Yes sometimes toothache refers to headache especially when the upper teeth are affected. Whatsoever it would be to get it chracked by your dentist fir secondary caries and go to your physician as well to eliminate the cause. Hope thus helps you
