Cloves have long been used in home remedies to treat for toothache pain. The eugenol that provides the flavor of cloves is also a pain-reliever and can help relieve inflammation. Look for clove oil (or oil of cloves) in the tooth care section of a drug store. Be aware that it can be toxic for children, so keep any clove oil out of reach and use only child-safe, diluted preparations on children. Read the directions carefully and consult your dentist or pediatrician if you have any doubt as to the safety.
