Does anyone know how to cure toothaches after an extraction?

My mom has been miserable ever since she had a tooth extracted that had a cavity. She has been told to use salt water and motrin to ease the pain, but it only helps her so much and later after it wears off, she will feel terrible. I would like a solution that does not require medication, but something like a home remedy that will last a while and feel great.The first with a good answer will get ten points! I don't want a link, just a straightforward answer. If any doctors or dentists are out there, you help will be greatly appreciated.
