Clove oil is applied directly to the gums (used topically) for toothache, for pain control during dental work. It is also applied to the skin as a counter irritant for pain and for mouth and throat inflammation. via MedlinePlus
You can use clove oil directly on the gum to relieve pain but frequent and repeated application of clove oil in the mouth or on the gums can sometimes cause damage to the gums, tooth pulp, skin, and mucous membranes.
To be on the safe side, use an all-natural clove oil toothpaste every 2-3 days.
