Tooth extraction is the removal of a tooth from its socket in the bone, typically performed when a tooth is damaged beyond repair due to decay, infection, or trauma. It may also be necessary for impacted wisdom teeth, overcrowded teeth, or to prepare the mouth for orthodontic treatment. The procedure can be simple, involving the loosening and pulling of the tooth, or surgical, requiring an incision in the gum if the tooth is not fully visible. After extraction, care is taken to manage pain, promote healing, and preserve the surrounding teeth and bone. Tooth extraction is often a last resort when saving the tooth is not possible.
