A tooth extraction is a dental procedure in which a tooth is removed from its socket in the jawbone. It is typically performed by a dentist or oral surgeon under local anesthesia to numb the area and minimize discomfort during the procedure. 

Tooth extractions may be necessary for various reasons, including severe decay, gum disease, overcrowding, or trauma. During the extraction process, the dentist or oral surgeon will carefully loosen the tooth from its socket using specialized instruments before gently removing it. Following the extraction, the dentist will provide instructions for post-operative care to promote healing and prevent complications.
