What does the research say?
Traditional use
These are traditional uses, not proven treatments.
Based on long-standing use, the European Medicines Agency recognizes clove oil as a traditional herbal medicine for adults:
- Minor inflammation in the mouth or throat (as a 1% to 5% mouthwash)
- Temporary relief of toothache from a cavity (applied to the tooth)
Cloves are a kitchen spice also used in medicine and cosmetics. Clove oil is a popular natural remedy for toothache and gum pain.[2]
Laboratory & animal research
Lab and animal results show what might be worth studying in people. They don't show that the herb has these effects in humans.
In lab tests, clove essential oil, which is rich in eugenol, killed bacteria and fungi, reduced inflammation and relieved pain. It hasn't been tested for immunity in people.[2]
In short
Clove oil can irritate the mouth and gums and cause allergies.
