Toothaches are often the result of dental cavities or an oral infection, according to the University of Maryland Medical Center. Toothaches also can be a symptom of other medical problems, such as a sinus infection or earache. Over-the-counter products are available to quickly but temporarily relieve toothaches, and you also can try some home remedies. In either case, you will need to see your dentist to address the underlying cause.
Apply an over-the-counter toothache pain relief gel to the affected tooth. The gel, sold under a variety of brand names at drug stores and pharmacies, should contain benzocaine, which is a local anesthetic.
Rub ice on the area that is giving you pain. This should reduce the pain for a while. Repeat as necessary.
Combine bayberry bark with vinegar to create a paste. Rub the paste on the affected tooth to ease the pain. Bayberry bark is sold at health and natural foods stores.
Add a few teaspoons of salt to a glass of cold water. Rinse your mouth with the salt water for several minutes. Repeat every hour or so to help reduce pain.
Rub some garlic with a little rock salt on the affected tooth.
