Call your dentist: Does your dentist have an answering service or a machine to relay messages to him/her? Most dentists take emergency calls. If not try another dentist...Get a referral from a friend, neighbor, or family member. Or, call your family doctor for a prescription for an antibiotic.

Oil of cloves: Go to the dental section of a pharmacy and look for a temporay filling material that among its ingredients is ":oil of cloves" or eugenol. If you can get it into the hole it will provide some relief.

Hospital: Go to hospital or emergency care and ask for pain and antibiotic for your toothache until you can get in to see your dentist.

Dental society: Your local dental society may have a dentist on call. You may have to get to an emergency depart. At a hospital.
