Clove Oil
Dab some clove oil directly on your bad tooth. Clove oil has remarkable bacteria-slaying properties — and it also has a numbing effect, which is why it’s a longtime folk remedy for toothache. In the 1800s, when toothpaste was scant and dentists employed tools of torture, every doctor carried a good supply of clove oil. Today we know that this extract from the clove bud contains eugenol, which acts as a local anesthetic. The oil may sting at first, but then blissful relief sets in.

Whole Cloves
You can get the same numbing effect from whole cloves. Put a few in your mouth, let them moisten until they soften, bruise them a bit between your non-hurting molars to release their oil, then hold the softened cloves against your painful tooth for up to half an hour.

No Cloves? No Problem.
If you don’t have any cloves, make a paste of powdered ginger and red (cayenne) pepper. Pour the powdered ingredients in the bottom of a cup, then add a drop or two of water to make the paste. Roll a small ball of cotton into enough paste to saturate it, and place it on your painful tooth. (This can irritate the gums, so keep the cotton on the tooth.) In addition to using the spices together, you can try them separately. Either one can help relieve tooth pain.
