clove oil: clinical use

Prescribing considerations

• Limit use to temporary symptomatic relief pending dental assessment.
• Confirm application will be confined to the affected tooth cavity and counsel against repeated gum exposure.
• Consider accidental-ingestion risk, particularly with young children in the household.
• Review anticoagulant therapy and possible bleeding risk.

Contraindications and cautions

• Hypersensitivity to clove oil, eugenol or Peru balsam.
• Teething.
• The selected product is not recommended for children under 2 years because adequate data are lacking.

Monitoring

• Check for mucosal irritation, ulceration, dermatitis or sensitisation.
• Ensure persistent toothache, swelling, fever or other signs of dental infection receive dental assessment.
• After ingestion, urgently assess neurological status, glucose, acid–base balance, coagulation and liver function.

Clinical pharmacology

Clove oil acts at the application site. Eugenol contributes local analgesic and anaesthetic effects, including through inhibition of voltage-gated ion channels. Human pharmacokinetic data are unavailable.

Formulation and product differences

• The selected licensed product is a clove oil 100% v/v dental solution with no excipients.
