There are two useful aromatherapy remedies you can use to treat toothache as first aid before you visit the dentist.
• Put a drop of clove oil on a cotton wool bud and apply it to the affected tooth. Clove is analgesic, helping to relieve pain, and is also a powerful disinfectant that can help prevent infection. If there is a large hole where a filling has fallen out, pour a drop or two of clove essential oil onto a small wad of cotton wool and insert it into the cavity.
• Apply hot compresses to the outside of the face near the affected area. Use german chamomile or roman chamomile as they relieve pain and inflammation.
