Migraine headache causing 1 tooth to ache?

your question should've been : tooth ache causing migraine? Not the other way around.

So yes, tooth ache can cause migraine, go to see a dentist to treat the tooth and hopefully the headache is gone..

The most likely thing is that the tooth is abscessed and is causing the migraine. One way to know is to fill a glass with hot water and then hold it in your mouth 30 seconds. if the tooth starts"throbbing" it's the tooth. When I get a migraine, which is seldom now, my tooth hurts and it is not infected. To control migraines or eliminate them, take 2 feverfew capsules daily. I had migraines twice monthly and they were bad. After I started taking feverfew daily, the migraines only came once a year, or less. Get better fast.

ps I get Solaray excipient free feverfew online(excipient free means no pesticides used in growing)

Yes sometimes I feel as if I could pull my teeth out. My son has had migraines since he was three and has just finished going to a chiropractor to adjust his spine. He has not had a migraine now for over two months. Its worth ago!
