Can i get a headache from a toothache ?

Yes: Yes, it's possible to get a headache from a toothache. The headache can also be independent of a dental problem. If you have a toothache, see a dentist to get it evaluated and treated before it gets worse.

Yes: Especially if the offending tooth is in the upper arch. The swelling associated with an infected tooth can cause regional pain. Plus, the teeth are all connected to the trigeminal nerve...It is one of the cranial nerves (it comes directly out of the brain-not out of the spinal column). There is a lot of 'referred' pain from teeth (pain sent to another location).

Yes: A toothache can cause many symptoms including fever, headache, neck ache, radiating pain, etc...

Absolutely: Tend to that problematic tooth and feel better soon...

Of course: In people who have headaches, a continuous, sustained toothache can easily trigger one of the episodic headaches such as migraines or any other primary headache. See a dentist ASAP.
