Can clove oil be used for a toothache?
A labeled dental-use clove product may provide brief temporary comfort, but it does not treat the cause or replace dental care.
The short answer
Traditional and regulatory contexts describe short-term local clove-oil use as a provisional measure. Do not put undiluted essential oil broadly on gums, do not swallow it, and do not use it for children or adolescents. Fever, facial swelling, drainage, trauma, worsening pain or trouble swallowing or breathing requires prompt care.
