ear and toothache

i have been suffering with this problem for over a year now. have been going to the doctors and dentist but this has not helped
the pain alternates from my left ear to the back teeth on my left side, sometimes they both hurt together

i seem to notice it more at night. it is very on and off as in i will suffer for a few months and then it will stop by itself, i have just started suffering again after a few months, i do not get pain anywhere else.

when i went to the doctor on the last oocasion they told me it was tmj and that i should take tablets like quiet life or calms, i took these for a while but they did not help, the pain just went itself (i think).
the doctor thinks i am biting or grinding my teeth at night but my partner says he never hears anything so i dont know what to believe

i keep getting worried that i have an ear infection because the first time i went to the doctors they told me it was, but everytime after this they said nothing was wrong - it will just take time to heal

i really would like a remedy that will ease the pain, even though it is not a sharp pain, it is just dull and annoying

any advice would bemuch appreciated

thanks in advance
