Understanding the Metallic Taste After Tooth Extraction

Common Causes

  • Amalgam fillings: Dental amalgam contains silver, tin, copper, zinc. When a tooth is extracted, these metals can contact saliva, producing a metallic taste.
  • Blood: Bleeding from the socket—blood has a metallic (iron) taste.
  • Medications: Local anesthetics, antibiotics, or other drugs used during the procedure.

Duration

The taste usually resolves within a few days as the socket heals. If it persists beyond a week or is accompanied by worsening pain, swelling, or fever, contact your dentist.
