Why do you have a metal taste after having teeth pulled?

The metallic taste after having a tooth pulled is likely caused by the amalgam fillings that are used to fill cavities. Dental amalgam is a mixture of metals, including silver, tin, copper, and zinc. When the tooth is pulled, the metals in the amalgam filling can come into contact with your saliva, causing a metallic taste in your mouth. Additionally, the damage caused by the tooth extraction can lead to bleeding, and blood has a metallic taste. The taste can also be due to the medication used during the procedure.
