While Clove Bud essential oil helps relieve pain and swelling, it should not be ingested or used orally. If you have a toothache, dilute Clove Bud oil with a carrier oil and gently massage it into your cheek or along the jawline, but avoid getting it in your mouth and do not apply directly to the teeth or gums. If pain worsens or persists, contact your dentist right away.
