How can i get rid of a headache due to a toothache?

Fix toothache: Most likely your headache is referred pain from the bad tooth. You need to address the toothache. You may have to start with antibiotics for the tooth, then what ever that can be done to fix the tooth such as root canal or pulling the tooth ot other. Hopefully this will take care of the ha. I would not delay treating the tooth. Get antibiotics now and see dentist as soon as possible.

Jaw precautions: Start with an antiinflammatory medication such as alleve, Motrin or advil, (ibuprofen) ice the area that hurts, adopt a soft diet and then make an appointment with a dentist asap.

Ibuprofen: Ibuprofen (brand names include motrin, advil) are very effective for toothaches. If Ibuprofen isn't enough to reduce the pain even temporarily, call a dentist. Most dentists would consider this an emergency and should be able to evaluate you within 24 hours.
