Seeing your dentist would be the only way to really know what's going on with your teeth. Toothaches can sometimes cause ear pain. Toothaches can be causes by numerous things such as infection, abscess, cavity, etc. The nerve is irritated and an exam is needed to know for sure why you're experiencing pain and to determine the best solution.
When I was 8 weeks pregnant I had an awful headache that only went away when I would stand up. I needed a root canal and once I had it done no more headache. You should see your dentist.
@mrsclarksonlee, any advice?
