Tooth extraction is a dental procedure in which a tooth is removed from its socket in the bone. This is often necessary when a tooth is severely damaged due to decay, trauma, or infection, and cannot be repaired with other treatments such as fillings, crowns, or root canals. Tooth extraction is also commonly performed for impacted wisdom teeth, overcrowding, or advanced gum disease that compromises the stability of the tooth. Depending on the complexity, the extraction can be simple (for visible teeth) or surgical (for teeth that are broken or below the gum line).
