Eugenol oil dental
Eugenol is used in some dental materials, but concentrated clove oil cannot treat decay or infection and can injure oral tissues.
The short answer
Eugenol is a clove-derived compound used in some dental materials, but concentrated oil is not a treatment for decay or infection and can injure oral tissues.

What is the direct answer?
What does this question mean?
Eugenol is an aromatic compound found in clove oil and used in materials such as zinc oxide eugenol temporary cement. Dental use involves controlled formulation and placement, not applying undiluted oil to a tooth or gum.
What can you do next?
Do not place concentrated clove oil in a cavity or on a sore gum. Rinse away accidental contact, avoid swallowing it, and arrange an examination so the cause of pain, ulceration, or swelling can be identified.
When should you seek dental care?
Seek prompt care for chemical burning, worsening pain, facial swelling, fever, or trouble swallowing. A persistent ulcer or sore area also needs examination rather than repeated home applications.
What should you ask the dentist?
Ask whether a eugenol-containing material is planned, what it will do, and how it will be removed or replaced. Ask what to use for pain while the tooth or gum problem is being treated.
Frequently asked questions
Can clove oil cure a tooth infection?
No. It may temporarily numb a sensation, but infection requires diagnosis and treatment of the tooth and surrounding tissues.
Why is eugenol used by dentists?
In a formulated cement, it can help create a temporary seal and provide material properties selected for a specific procedure.
