What is the quickest way to get rid of a tooth ache?

See Your Dentist: See your dentist to see what the problem is. There are several possiblities with several solutions based on the problem.

See the dentist!: It sounds too obvious, but toothaches are not treated definitively anywhere other than at the dentist's office. Medications do not cure the problem, they only mask or delay the pain. See your dentist as soon as possible!

See a dentist.: There is no better way to get rid of a toothache than to see a dentist and fix whatever is causing the pain. Medications cannot fix toothaches. They only mask the problem which comes back when you stop the medication.

See a dentist ASAP: Even though the tooth ache may be related to sinus or another source, i would start first by seeing a dentist whom can x-ray and evaluate the tooth and surrounding gingival tissue and bone.
